Some people think that the internship is a knock on the door of a good job, while the academic performance as long as you can get by. It seems that this argument is quite prevalent in the campus, a wind of impatience, and even in the highest school in the country such as Peking University, there are students in the paper message "I have no time to study because of the internship, please teachers to raise your hand," it is laughable. The following is what I bring to you the internship summary of three secondary students, I hope you can like!
Intermediate students internship summary of a
First, the internship unit
This apprenticeship unit is our Rudong County, a fertilizer plant, Mattang fertilizer plant, near our high school, high school, we can be fed up with it. Often the smell of ammonia. Although the fertilizer plant is not big, but in our area is already considered relatively large. The predecessor of the fertilizer plant is a medium-sized state-owned enterprise in Nantong. The annual output is 40,000 tons of synthetic ammonia, 130,000 tons of ammonium bicarbonate; 3,000 tons of dimethyl hydantoin; 1,000 tons of hydroxymethyl hydantoin; 200 tons of cephalosporin antibiotic intermediate 7-adca (7-amino-3-deacetoxycephalosporanic acid). The company covers an area of 320 acres, with another 303 acres of agricultural land, fixed assets of 120 million RMB, and nearly 400 employees.
II. Internship content, principle and summary
This time we only visited the production of synthetic ammonium bicarbonate, because this factory is mainly the production of this. And the factory people are still not too willing, who do not want to find trouble, and the factory pollution is very serious, everywhere is black, coal dust everywhere in the factory, the staff is also mostly do hard labor. The factory technician talked about the production process, and then I also looked up a little information. The main content of this apprenticeship is the synthesis of ammonium bicarbonate, of which ammonia synthesis is the main stage. H2 and N2 gas in high temperature, high pressure, the presence of catalysts under the conditions of the synthesis of ammonia.
In the gas production process, water gas is generated mainly from water. c+h2O-->co+h2 (collectively known as semi-water gas), of which water vapor is generated by the boiler. n2 is mainly from air, which is fed from the bottom of the tower to the hot charcoal layer. Since the coal contains sulfur, the gas contains H2S and SO2. it should be desulfurized, and after entering the cleaning tower, it enters the compressor to be pressurized, i.e. it enters the conversion process. This process converts CO to CO2. after which oil separation is carried out to protect the catalyst. The operation in the compressor can be called the refining section, removes a small amount of CO and CO2, its pressure is about 120Kg. after that, it enters the synthesis section, N2 + H2 -->NH3, using dilute ammonia and CO2 reaction to produce ammonium bicarbonate, ion dewatering to form ammonium bicarbonate crystals. This reaction is carried out in the carbonization tower. Because ammonium bicarbonate volatility is strong, and low nitrogen content, and now switch to compound fertilizer.
So the main products of the fertilizer plant are also quaternary ammonium alcohol, formaldehyde, dimethyl ether, methanol. In the presence of catalyst alumina, in the tube heat exchanger can be dehydrated to form dimethyl ether. They are all major chemical raw materials and chemicals. In modern life, in order to protect the environment, methanol can be used as a fuel instead of gasoline, and at the same time alleviate the situation of resource constraints.
The carbon dioxide used in the production of ammonium bicarbonate in the carbonation tower is used to absorb carbon dioxide in the conversion gas by using sleeping, which reduces the cost and also reduces the emission of carbon dioxide, a greenhouse effect gas. This is not bad at this time when the greenhouse effect is becoming very serious.
III. Feelings and gains
The visit to the apprenticeship soon came to an end, in this short period of time in the internship, the harvest and a lot of thoughts, I think this form of visit to the internship is very interesting, because it is sitting in the classroom than listening to lectures to a more practical, intuitive. Through the field visit, I feel that I really learned a lot of knowledge related to the profession, but also improve my ability to recognize and analyze problems in production practice. For future practical work to lay a foundation. But at the same time, also realized that their knowledge is so scarce, so in the future, we have to work harder to learn professional knowledge, fill their own blanks, and strive to contribute to the chemical industry in our country!
IV. Opinions and suggestions on the enterprise
think the enterprise should be more supportive of the students' apprenticeship, including internships, maybe your enterprise will need us in the future, we need to consider the long-term training of talents, and enterprises really need to pay attention to environmental protection, should be for the factory is not far from the middle school, and live a lot of students, a lot of people on the factory has long complained about it. If the economic benefits of the environment to get worse that is not worth the loss.
V. Opinions and suggestions on the course
The school of this apprenticeship is very good, not only to consolidate the knowledge gained, and in practice, the initial understanding of chemical production, to increase the factory insights. At the same time in the process of apprenticeship also learned from the students do not have the knowledge of the textbooks. Workers are enthusiastic, helpful, not afraid of hard work, not afraid of the spirit of tiredness is always worth learning. The school should offer more such courses, from the first year every semester should take us to visit some of the more well-known large enterprises, some high-tech industries, as well as to provide some internships, the curriculum and the work of the content of the link, so that the growth of students will be very helpful.
Summary of the internship for secondary students
Clinical practice is the consolidation and strengthening of the theoretical learning stage, but also the nursing skills operation of the training and exercise, but also the best training before our employment. Although this period of time is very short, it is very important to each of us. We cherish this time, cherish every day of exercise and self-improvement opportunities, and cherish this rare teacher-apprentice relationship with teachers.
Before the practice, it is the teacher of the department of science and education in accordance with our needs and induction requirements to arrange a unified training, including:
I. Understanding of the hospital profile introduction.
ii. Understanding the relevant provisions of student management.
iii. Know the general knowledge of public order management.
IV. Know the education of medical ethics.
V. Understand the writing of medical documents.
VI. Knowledge of nursing.
vii. Understand nosocomial infection.
viii. Understand knowledge of operating room.
In the meantime, the teachers of the Department of Education also interspersed to organize us to the wards to see the medical records, watch the expert lectures on medical disputes and first aid treatment video, so that we have a preliminary understanding of the actual clinical work, for the formal work of the laying of the foundation.
Just entered the ward, there is always a feeling of confusion, for nursing work in a relatively unfamiliar state, but also for their own in such a new environment can do or not a molded concept. Fortunately, we have teachers to introduce us to the structure of the ward, introduce the work, the rich experience of the teachers, so that we can adapt to the hospital nursing work faster. The ability to adapt to the hospital environment as soon as possible, for the practice and work in the hospital to lay a good foundation, which should be counted as the first harvest of the internship phase: learn to adapt, learn to grow and survive in a new environment.
The work of nurses is very heavy and messy, although in the past also have some feelings, but really into the wards, the feeling is deeper. Indeed, the nurse's work is very fragmented, very messy, can also be said to be very low, but through the majority of people do not understand, we find that the nurse has its unique charm. Hospitals cannot do without nurses, which explains the importance of nurses. Doctors can't live without nurses, patients can't live without nurses, and the whole environment can't live without nurses. This trivial work, with a complete system, can be said to be "small sparrow, all the organs", but also because of this, in order to play its unique role, produce an indispensable role. Because of the clinical practice, we have a more comprehensive and deep understanding of nursing, more specific and detailed understanding of the profession. The second gain of entering the clinical: a correct understanding of nursing, set up a correct view of professional ethics, and develop a good working attitude.
The first morning of the practice, I came to the hospital early, when the 8 o'clock shift had not yet begun, I followed the nurses to help the patients change the sheet, help them measure the temperature and so on. At 8 o'clock, the doctors and nurses handed over their shifts on time, and the doctors and nurses on duty last night reported on the situation of the patients, and then the doctors in charge of the beds began to check the rooms, and I followed them, listening carefully to how they checked the patients and how to ask them. Looking at their meticulous work attitude, my heart could not help but be filled with respect. First of all, the doctors questioned the patients, asking them about their illnesses, such as: whether they had fever, whether they had pain, how they ate and drank, whether their excretion was normal, whether they had polyuria and oliguria, etc. Then, the doctors carefully examined the patients and listened to how they examined them and how they worked. Then, the doctors carefully observe the patient's signs and sometimes make percussion, and finally give medical advice. At this time, the nurses began to compare the doctor's orders, and in accordance with the doctor's orders for medication and treatment, the nurse every four hours to check the temperature, and plotted temperature curves for the doctor's reference, in addition, every half an hour for the rounds, to check whether there is any abnormality.
In the afternoon, the doctors held a seminar for the patients in bed 14, and I came there quietly to listen carefully to their discussion and memorized the points. Without realizing it, it was already time to get off work. Back to the dormitory, I summarized today's gains and questions, and felt that today is really a full day!
I think the ward practice, the most contact is the patient, a deep understanding of a variety of diseases, mastered thoroughly is the basic nursing operation. The biggest and ultimate goal of the practice is to develop good operational skills and improve various nursing skills in advance. Therefore, under the principle of "letting go without letting go, letting go without letting go" of the teaching teacher, we actively strive for every opportunity to exercise, such as catheterization, bed shampooing, bed sassafras bath, automatic gastric lavage, intravenous infusion method and other basic nursing operations. At the same time, we continue to enrich our clinical theoretical knowledge, actively think about all kinds of problems, and humbly ask our teachers or other teachers for advice on problems we don't understand, and make good notes on our knowledge. When the teacher is not available to answer, we will look for books after work to better strengthen the combination of theoretical knowledge and clinical. Most of the practice departments in ______ hospitals are whole wards, and the nurses we work with are mostly nurses-in-charge. When we follow the teachers to take care of the patients, we will strengthen the observation of the condition, enhance the understanding of the patient's disease, and at the same time carry out the publicity of various health knowledge on the patients, which can exercise the application of the knowledge we have learned. According to the requirements of the hospital, we actively completed the writing of medical records, teaching room visits, lectures and so on, which cultivated our writing, organization, expression and other aspects of the ability. On the whole, the third harvest during the internship, but also the most huge harvest: nursing operation skills improved, the level of disease awareness rose, the nursing work gradually skilled, in the development of excellent vocational skills level at the same time also cultivated a good habit of learning, through reflection, to learn by example.
During the hospital practice, we do everything to the patient's health, disease regression for the purpose, we strictly abide by the hospital rules and regulations, all operations are strictly follow the principle of asepsis, the strict implementation of the "three checks and seven pairs". In the department, we are serious and careful to do a good job, abide by the principle of asepsis, the implementation of the checking system, and cultivate a good way of working, which should be counted as the fourth harvest, although it can not be said to be very big, but also very important, indispensable harvest.
After n days of internship, I have a preliminary understanding of clinical care, and learned a lot of new knowledge. First of all, medical ethics and medical style education let me actually feel as a doctor's sacred and pragmatic, we must set up a good image, do things adhere to the principle, in order to better safeguard the sacred authority of the white angel, in order to get the respect of patients and colleagues. Secondly, the lectures on specific clinical work, such as writing medical documents, nursing knowledge and nosocomial infections, made us realize how difficult it is to do a good job in clinical work with only theoretical knowledge. At the same time, on the correct treatment of the relationship between doctors and nurses, we have a perceptual understanding of the issue, doctors and nurses are equally important, regardless of who is bigger and who is smaller, our ultimate goal is to cure the patient. I think the nursing staff's work is more important and tedious, and deserves the respect of every medical staff. Also, by watching the video on medical disputes, I fully realize the high risk of medical work, and recognize the high standard requirements of the community on our medical staff, we must master skilled professional knowledge at the same time, learn to better deal with the doctor-patient relationship, the patient comes to us to see a doctor, they are our God, we must establish a sense of self-protection, to increase the knowledge of the law, and better at work! We must establish a sense of self-protection, increase knowledge of the law, and better exercise our duties and rights in the work.
Time flies, in this n days of practice, I not only learned a lot of nursing expertise, but also to a white angel identity into society. Although, in the practice of the time must get up early, the work is also considered more tired, but whenever I see the patient's smile after recovery, my heart really feel immense pride and pride! As a voluntary worker, our duty is to save lives and help the injured. Health depends on, life depends on! This is the oath of our medical students. In these n days, I understand the sanctity of being a medical student, we are the patient's angel. For this reason, we should do everything for the sake of the patients and try to do our best for them. This internship is our first social practice as medical students, but also for our future on the society to lay a solid foundation!
Internship summary of intermediate students
Today, across two semesters for six weeks of gold internship finally ended. Looking back on these six weeks of learning, I have a lot of feelings. I was in the q5 group in the first four weeks of study in fact did not put all kinds of work over again, we contacted the wire cutting, grinder gear, mold sheet metal, milling, turning, plc, rapid prototyping, heat treatment and so on a dozen types of work, some because of the English class or vacation reasons slightly shorter, but overall we are familiar with a variety of machinery during this period of time, the basic principle of work and the processing of the phase of the materials.
This is the first time I've been to the United States.
Looking back on these 6 weeks of learning, I think the most rewarding part of our profession should be the last two weeks of our internship unique "Gold Cup" design competition. The competition is divided into a, b group, a group including spring-powered car, electric direct sailing boat model design, b group including welding (small waist, bird's nest, the Eiffel Tower), surface treatment (Qingming Festival, plum, orchids, bamboo and chrysanthemums, unicorn), disappearance casting (Chinese copper phoenix lamp, China Pavilion), chess processing and so on. All kinds of technology can come together on a lively, if you use a hundred flowers to describe I think it is also said in the past.
I participated in the design of the electric straight ship model, also very powerful, the day of the competition, we have three times successfully sailed through the 10-meter waterway, only the first time to hit the wall once, the results were 19 seconds 94 seconds, 18 seconds 10 seconds, and 19 seconds 22. It is worth mentioning that the other participating teams the best results of 19 seconds 4 or so, that is to say, the top two of the competition results are our The top two times in the race were all run by our extreme airships, and even taking the average of the three times was 19 seconds 08, still much faster than the second place 's best time. Coupled with our windy shape, so the origin of the name of our extreme ship is not unusual "occasionally faster than our ship did not look good, than our good-looking ship did not give us power (of course, than our good-looking actually only organic creation of the catamaran only), so non-extreme ship of the title of the title does not belong to, hehehe."
As an internship report, I will not be like most people to tell you what kind of work I learned on what day, and then mastered what skills, in fact, these are bluffing, you can say that those mechanical operations you learn a day, two days on a complete mastery, will not forget? Impossible, only after practicing really think about it, that is not in vain gold internship one.
So, I would like to share with you some of the experiences and thoughts of our ship modeling phase. If the six weeks are divided into two phases, compared to the first four weeks can actually be described as theoretical learning (learning how to use those mechanical equipment only), and the last two weeks of the "Gold Cup" should be our practical stage, to complete a piece of work, you should how to design your products, what technology processing techniques, how to get the material processed well, these are To be able to process the material well, these are not the first four weeks in which a separate type of work can solve the problem, only to the front of the learning to be integrated, and then supplemented by teamwork, in order to really do a good job of a piece of work.
In these two short weeks, we roughly divided it into three phases: the first three days were the design phase, the next week was the production phase, and the last few days were the debugging phase.
At the beginning of the design of our extreme airship, we didn't really know how our boat should look like, but under the ****some discussion among the team members, we came up with the following three goals:
1. The boat can sail stably and won't capsize;
2. The boat can sail in a straight line, avoiding curve sailing or spinning in place;
3. The boat can minimize drag and try to go fast under the previous two principles.
Because of these guidelines, we spent three days quickly designing our three-dimensional model, of course, that is only the first draft, there are many changes in the production process, but it is these clear goals to make our boat completed on schedule.
When it came to the production stage, we found that it was not easy to make curved surfaces out of aluminum, so we minimized the curved surfaces in the design, and then we made a model out of a4 paper before tracing the dimensions on the aluminum plate and cutting it out. The hardest part of the design was the surfacing of our bottom pontoons. This is the most important part of our hull design. The two inner pontoons are vertical surfaces, sticking straight into the water to stabilize the flow, reduce the resistance, and also serve as a rudder, while the outer side is the only curved surface in our overall design, and it is also the most difficult to make, and at first we had to scrap two pontoons because of poor consideration. However, because of the pontoon design, our hull will not tilt even if it is placed on the ground, not to mention the water surface, and it is the most stable one among all the competing models when sailing without any tilt. And because of the design of the inner vertical side of the pontoon, our boat is the straightest one, three times sailing, only the first time because of the water into the slightly put ___ before hitting the wall once.
After the upper, middle and lower parts of the hull were done and assembled, we followed with the design of the drive train and the installation of the power system. At first we envisioned a double screw, so we thought of using a gear disk, but the energy loss in the transmission would be huge. So we accepted the suggestion of our instructor, Mr. Zheng, to use a single propeller, with the shaft and the motor connected by plastic tubes, which greatly reduced the loss of any intermediate links. In the meantime, we also encountered some difficulties, but they were all overcome by our team one by one. First of all, our shaft is made of 3mm round steel, which is a very good material for the shaft because of its smooth surface and high hardness. But also because of the round steel hardness is too big, so we manually can not make threads, even if we ask the teacher is also unable to help, but not far away from the drilling machine gave us inspiration, we will take down the drill bit, put the shaft into the vise is clamped sheet metal wire, so the shaft in the rotation of the sheet metal wire slowly pressed into a circle of threads so out. Similarly, we had a similar problem with our bushings, which were 6mm in diameter and had to be drilled out to a 3.3mm diameter. At first, the teacher also thought it was impossible, fearing that the sleeve would be deformed and bent due to excessive force during the drilling process. But we didn't compromise because although the bushing is a small part, without it our power system would not work. So we decided to try it anyway. I didn't think it would work at first try.
Well, after the main parts of the power system were machined and assembled, it was time for debugging, and initially we tried many propellers, and even the same propeller was sometimes unstable. So, it's also hard for our propeller designers and ship debugger, if it wasn't for them, we wouldn't be able to get such a good result from our very best ship, again, I salute them.
In fact, I have learned a lot from these little things: often, there is always a voice around us that says, 'This is going to be difficult, you can't do it, you can't do it.' Then we start to doubt, and we start to retreat. Then we begin to doubt, begin to retreat, so we really can not, really can not do it.
In fact, there are only two kinds of people who make this noise, the losers, who never succeeded when they were in the same situation as you, so they themselves feel it's very, very hard, so unfortunately, when you meet them and ask them for advice they tell you about their own inner fears, and once you're not determined enough, you become one of them. For example, if you ask a person who often fails in math, ask him if math is difficult, he will tell you that math is very difficult, sometimes really want to die on the wall; but if you ask a person who often get a hundred points, he will say that those math problems are very simple to death, can do it with their eyes closed. This time you will think?
The second kind of people, they have not tried, but do not want to try, and do not want you to try, so he told you that it is impossible, told you not to waste effort. This kind of person is actually more hateful, because the former kind of person he said is sincere, he really think it is very difficult very difficult; but this latter kind of person is not so, he did not try, how will know the difficult is not difficult, can not work? Einstein once said: "to promote the development of the world only two words, that is, 'thought', and make the world stagnation is only these two words. And these are the very type of people who ruthlessly stifle your thoughts. Just a few words from these people can kill your thoughts, drive away your curiosity, and make you gradually lose yourself, completely at their beck and call, and from then on your mind will begin to think according to his way of thinking, and you will no longer be you because you no longer have a mind of your own.
So I would like to say is: maybe life on the road there are too many voices tell us not, impossible, but we can let go of the courage to do, to reap the success of our own; maybe life on the road there are a lot of failures, but please believe that as long as you insist on a little while longer, the success of the front of you; do not let others, so that the failure of the left and right of your mind, and always do the most most real! Don't let others and failures sway your mind, always be the most true to yourself. It is said that confident women are the most beautiful, I think I have to add: confident men are the most successful.
Of course, I do not blame our teachers mean, I just from this little thing inside got some more profound things, I hope the teacher saw the first two paragraphs do not misunderstand it.
