Practice is the basis of innovation, leaving the practice, innovation becomes the wood of no origin, the water of no source. Experience tells us that innovation should start from the actuality of everything. The following is my compilation of "accelerate the implementation of innovation-driven development strategy: science and technology innovation theme argumentative essay example", I hope it will help you.
Technology and innovation theme essay sample (a)
Our lives have changed dramatically with the development of science and technology.
In the past, people could only rely on horse-drawn carriages or walking, but now people have cars, trains, airplanes, and transportation in all directions. In the past, people who wanted to say something to their relatives far away from home could only do so by writing letters, and it took a long time for the other party to receive them, and if they wanted to write back, it would take a few more weeks. It was even more difficult for them to see each other. Now, with the development of science and technology, you only need to take out your cell phone and dial the number to speak to your distant relatives, and then wait for a while to speak to them. You can also video chat, it's really "far-flung" ah!
In ancient times, people lived in simple tiled houses, but now in big cities, dozens of high-rise buildings can be seen everywhere. People from the previous fire cooking to the current "automatic rice cooker". From the old days of lighting a fire to keep warm, people now turn on the air conditioner. What is the reason for these changes? It is technology!
Technology not only makes our lives more convenient, but also allows us to protect our health. In the past, people who got a little sick may lose their lives. But now, medical technology is becoming more and more developed, can cure almost all the common diseases in life, greatly extending people's life expectancy, so that people can have more time to enjoy life.
Technology not only allows us to meet our material needs, but also makes our spiritual world more fulfilling. In the past, people did not understand the things of the world, many phenomena are full of incomprehension, can only rely on speculation to judge. And now, with the development of science and technology, people send satellites into space, see a picture of the Earth, know that matter is composed of a variety of molecules, atoms, know ...... that this is the work of science and technology.
The development of science and technology has brought a lot of benefits, but it is also a double-edged sword. Because of the development of science and technology, people invented computers, computers bring convenience to people's lives, but now addicted to the network of students more and more. People invented the automobile, which brings convenience to people's traveling, but the harm caused by car exhaust to the environment is huge. All these phenomena show that the development of science and technology is both favorable and harmful. But as long as we use it wisely, it can create a better tomorrow for us!
Technology and Innovation Theme Essay Sample (2)A large part of the electricity bill that our family pays every year is on air conditioning cooling and heating costs, like air conditioning, heating such items: although it can provide us with a good environment of warmth in winter and coolness in summer, but also consumes a lot of energy. Let's talk about air conditioners: not only do they use a lot of electricity, but they also emit a lot of Freon, which is harmful to the atmosphere (although there are now CFC-free air conditioners). One day, I asked my dad, "Is there anything that doesn't consume energy and keeps people warm in winter and cool in summer?" My dad gave me a strange word: "phase change materials."
So I collected some information from the Internet and found that phase change materials can be used for many purposes. Phase change materials are substances that change form with temperature and provide cold or heat (latent heat). The process of changing a phase change material from a solid to a liquid or from a liquid to a solid is called a phase change process. That is, the phase change material will inhale or release a large amount of cold or hot energy.
Usually the most common phase change material is water, when the temperature to 0 ° C or lower, liquid water into solid ice. When the temperature is above 0°C water changes from solid to liquid. Assuming that in the summer, a large block of ice is placed in the house, the house cools down immediately, and the ice melts in order to maintain a constant temperature with the house. This also proves that in the process of melting will inhale a lot of surrounding heat energy and release cold energy.
Many of China's scientific and technological research organizations have studied this topic and published numerous papers. However, phase change materials have not been widely used for fear of the dangers of producing them. In the past few years, due to significant progress in materials research, the stability of phase-change materials has reached tens of thousands of phase-change cycles without changing their properties, which has also made phase-change materials reach a practical stage.
There is a technical principle is through the absorption of solar energy or absorb a large amount of cold energy in the winter, you can store heat or cold energy in the physical structure of the phase change material, with this material to build the walls of the house, when the outside temperature is lower or higher than the heat storage temperature (heat storage temperature is not fixed, generally in the 20 ~ 25 ℃), the phase change material in order to achieve the equilibrium temperature to produce a release of thermal energy process of the phase change, to achieve the purpose of the wall can also be thermal insulation, and to achieve the purpose of the phase change. To achieve the purpose of the wall can also be insulated.
For example: need to ship a biological sample from China to the United States, the total **** need 13 hours, the temperature requirements are: biological samples to maintain a constant temperature between +2 ℃ to -8 ℃. By making a blanket of phase change material to wrap around the outside and placing it in a small box with a constant temperature between +2°C and -8°C inside, the goal can be achieved.
Knowing that phase-change materials have so many uses, I really hope that Beijing will be the first region to enter the "phase-change materials world". Now Tsinghua University has a separate section on phase change materials. Even some people on the Internet said; "It can be predicted that in the next few years phase change materials will be widely used in our country, especially in Beijing."
Technology and Innovation Theme Essay Sample (3)It's time for the annual Science and Technology Festival, and it's a great day, a special day for all of us in the school.

I took part in the competition of the bamboo dragonfly and the hovering airplane.
The real excitement of the event came during the competition, which was held at noon on Wednesday. Although the sun was beating down, there were still a lot of people in front of the school's information center. I and Prince Chen a group, the competition site in the square on one side, within the limits of this range, within the range of the comparative stagnation time and flight distance, at that time, I felt that I flew is not too far, probably only two meters, but our class Chen Shuaihua students flew out more than six meters, although the results are not yet known, but I believe that our class must be very good.
The most exciting game is Thursday afternoon paper airplane target shooting and levitation, the competition venue in the school's stadium, very lively gathering of the first year, the second year of all students and teachers. I and seven other students than is hovering.

Science and Technology Innovation Theme Essay Sample (5)
I have a dream of science and technology, I hope that the motherland in the future things have become high-tech.
I will produce this idea is because: I went back to the countryside with my mother home, see the grandmother is still riding a very old tricycle, which is nothing, but in the uphill especially strenuous, and not yet ridden up, a head of sweat.
In the summer, the house is hot and stuffy, the electric fan fan out of the hot wind, walking outside, at any time may be baked, hot people can not stand. The water in the river is also burned into hot water, can't even touch it. Even the livestock can not stand, hot straight run.
In winter, the only thing that can keep you warm is a thermos, a hot water bag. You also need to wear heavy clothes. When the wind and snow come, freezing people shivering, face, body like being cut by a knife, hand frozen bleeding, pus, purple, can only take a towel in the water to soak a bubble, bear the pain, little by little wipe. The river freezes ice, adults to wash clothes with the water here, take the stone half a day to smash not open, can only be in the side of the anxious round and round.
