Visitors, now we are in the Museum's Science and Technology Park, which is a science and technology theme park characterized by natural garden style, the park *** is divided into three scenic areas, namely, outdoor recreation area, outdoor recreation area and scenic excursion area.
In the outdoor recreation area we first saw these large-scale exhibits, is very popular with teenagers and friends of the expansion of the rock climbing training program. Teenagers and children can exercise their physical coordination and cultivate the spirit of perseverance and hard work in rock climbing training.
First of all, I will lead you to visit the museum of the universe to explore the secret exhibition area. This is the highest location, located in the top floor of the Museum of Science and Technology.
Cosmic exploration of the exhibition area is divided into interstellar fantasy, experience adventure, space theater, the road to exploration, digital microcosm and so on several small exhibition area. Here, we can visualize the universe, the solar system, and space knowledge, as well as conduct mysterious exploration of the Star Fantasy exhibit area through participatory activities.
Satellite technology is one of the cutting-edge technologies. If mastered, it can make our science and technology realize a new leap forward. However, it is not easy to make a satellite. on April 24, 1970, China's first artificial Earth satellite flew into the sky. Many comrades who participated in the satellite development mission were so excited that they burst into tears, and the whole country was in a state of jubilation. The one next to me is the model of the Dongfanghong No. 1 satellite.
When the satellite from the vastness of space to the Earth to send a clear and pleasant "Dongfanghong" music, the Chinese land at the time all boiled, hundreds of millions of people to the streets for our country's successful launch of satellites, into the field of space research cheered and jumped, and at the same time also reflects the country's economic, scientific and technological, social and military capabilities at that time! The level of development of the country's economic, technological, social and military capabilities.
It is opposite this exhibit is according to the 1 to 1 scale production of the "Courage" Mars rover model. 2003 June, the United States launched this Mars rover into space. The rover lasted more than six months and arrived at Mars on January 13, 2004, Beijing time, and carried out exploration and research activities on Mars.
Courage weighs 175 kilograms, is 2.1 meters long, 1.6 meters wide and 1.5 meters high.
Through the projection is the real picture of the rover through the long and arduous journey of more than six months, and safely landed on that distant and mysterious planet.
This is the rover's camera taking photos of Mars, and the robot collecting soil and minerals on the surface of Mars, and then analyzing and processing the data by computer to send it back to the Earth to help human beings carry out scientific exploration of Mars.
Displayed on my right is a simulation of Shenzhou's liftoff developed by China itself, a system that includes a launch vehicle, a launch tower, a launch command center and a projection demonstration. It simulates the whole process of the Long March 2F rocket carrying the Shenzhou spacecraft to work in space and the return of the return capsule.
When the rocket ignites, lifts off and flies out of sight, tourists can track and observe the separation of the escape tower, the separation of the booster, the separation of the first-stage rocket, the throwing out of the fairing, the separation of the arrow and the ship, the unfolding of the solar panels, the spacecraft's entry into orbit, as well as the return capsule carrying the astronauts back into the atmosphere and landing safely in the predetermined recovery site through the screen above.
Our next entry is the Space Theater exhibit. In this exhibition area set up space seats, space station, three-dimensional rolling ring, rocket display and other large-scale projects, you can personally feel the hard work of astronauts training, experience the fun of space travel, from which to understand the development of China's rocket history.
So I'm next to this hanging in mid-air is the parachute wing machine, through the joystick, control glide climb, dive, or to the left or to turn. The screen will also show the speed and height of your glide, so you can enjoy the excitement of flying freely between the mountains and the white clouds, and after a few minutes, it will also show the picture of your successful landing.
In the process of our exploration of the universe, we gradually found in the vast universe of the Earth is not the only planet, with the continuous improvement of human awareness, our understanding of the universe is also increasing, currently recognized by our fellow mankind gold, wood, water, fire, earth and other eight planets, in our Museum of Science and Technology has also done the relevant display. For example, we are now seeing the eight stars weighing. It gives you an idea of the various changes in body weight that occur when you are in the various planets of the solar system.
Please follow me through the time tunnel to explore the mysteries of the stars and watch the representative models of ancient astronomical instruments of our country and some other countries.
There are some interesting questions to be answered here. For example, what is the difference between an armillary sphere and a simple sphere? How did the ancients keep time without alarm clocks? How to know the position of the earth quickly and easily with a globe? How to know the position of the stars without being affected by the climate?
The formation and characteristics of wetlands, forests and deserts, and their impact on human ecological balance are introduced in front of us through a sand table and live scenes. Together with earthquake simulation, flood simulation and volcano simulation, as well as exhibits such as man-made ecological realities and models of various kinds of plants and animals, we learn about the geological formations of the earth.
Through visitors' personal participation in simulated earthquakes, as well as volcanoes, floods, tornadoes and other demonstration projects, thus arousing visitors' perceptual understanding of natural disasters. That is, while enjoying a happy life, people have to protect the human homeland twice as much.
Here is the Ocean Adventure Zone. Here, we participate in virtual fishing, undersea adventure, as well as simulation of navigation and other five large exhibits, so that visitors feel the depth of the wonders of the ocean, and personally experience the thrill and fun of sailing the sea voyage.
Protecting the environment and conserving resources is a topic we have always called for, and the exhibition area we are about to enter is to advocate that tourists and friends should have the awareness of caring for resources and protecting the environment.
With the large amount of industrial wastewater, coal, oil and other non-viable resources depletion, human awareness of environmental protection is getting stronger and stronger, the use of new energy generation has become an inevitable development trend.
The exhibit you see now is used to demonstrate how five different energy sources are used to generate electricity.
Viewers are invited to choose one of the power generation modes at random, press the corresponding button on the edge of the sand table, and the corresponding model will automatically demonstrate. Nowadays, the phenomenon of water pollution is becoming more and more serious, and the treatment technology of industrial wastewater is getting more and more attention from people. So, can industrial wastewater be processed to achieve purification standards and reuse it? This dynamic simulation of industrial wastewater treatment demonstration device, to give us the best answer. Please look here, we can see that the wastewater in the wastewater tank through the pump and flow meter was transported to the micro-electrolysis bed, in the micro-electrolysis bed with iron filings and carbon particles in the chemical reaction, the fe3 + into fe2 + as a coagulant, along with the wastewater to the coagulation tank with the mixer in the upper part of the mixer, add alkali adjustment of the wastewater into a weakly alkaline, and at the same time add a small number of polymer flocculants to produce coagulation, so that the water of the colloidal Pollutants attached to the floc, the above is the primary treatment process, known as chemical treatment; after the primary treatment of wastewater and then enter the secondary treatment system, microorganisms in the aeration tank will be harmful substances decomposed into simple harmless organic or inorganic matter, in the second sedimentation tank, activated sludge and has been treated wastewater solid-liquid separation, this is the secondary treatment process, is biological treatment, the tertiary treatment using quartz sand and pebbles to filter the impurities in the water, and the black in the adsorption column is activated carbon to remove the odor in the water, which is a physical process. After three steps the water can be used for fish farming and irrigation.
The next thing you enter is the Smart Masters exhibit. Most of the technology combining virtual and reality is utilized here. Here you can experience the feeling of entering the studio, you can also experience the holographic audio to bring you a super realistic sound quality feeling, but also can play soccer, volleyball and so on, you can feel the virtual technology here to bring the sports experience.
The red area in front of the museum is distinguished from other venues, especially the establishment of the overall fire exhibition area, it is "ornamental, interesting, advanced, educational, interactive" as the overall requirements for the design to produce physical dynamic model-based, *** sub-fire basic knowledge, common types of fires and extinguishing demonstrations, fire, fire alarm, fire rescue linkage demonstrations, and the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire, the fire and the fire. Alarm, fire rescue linkage display, fire escape shadow demonstration and other parts. Let the audience in the entertainment to obtain knowledge and deepen understanding. In this exhibition area, visitors can escape from the simulated fire in the exercise, you can choose the correct fire fighting equipment through the exercise, looking for accurate fire extinguishing points, but also through the phantom imaging technology, to watch the whole of the high-rise fire extinguishing real scene.
The next thing we came to is the robot exhibition area: this wonderful robot uses an electric drive, which drives the robot to make various actions through gears, chains, connecting rods and other transmission mechanisms. The robot is also equipped with tactile, photoelectric, sound three sensors, so that the robot has a "tactile", "visual" and "auditory" function. Playing saxophone robot with artificial lips and artificial throat, relying on air pressure device, can play a beautiful saxophone music.
All along the way is the crystallization of human wisdom, which in turn caused us to want to learn about human beings themselves. Human origins exhibition area can let us understand the process of human development, and in the process of human development of various by-products, like the four great inventions and so on. Here you can also see the enlarged heart model, the human skeleton model, which reveals to us the human body science and the mystery of human body structure, showing the function of the various tissues and organs in the human body.
This is an interactive simulation of the human skeleton. When the participant and the human skeleton model, each stepped on the bicycle connected by the transmission mechanism, then, using the principle of semi-transparent and semi-reflective mirrors, we can observe that the participant's legs and the human skeleton model of the leg bone movement posture completely "superimposed"
This is the heart model. This model shows that the heart consists mainly of left and right atria, left and right ventricles and valves. The audience is invited to watch the heart at work.
Please look through the Plexiglas shell to see the various organs being dissected inside the human body, as well as a demonstration of the functions of the major organs, such as the respiratory system, the digestive system, the blood circulatory system, the urinary system, and the mechanism of life occurrence.
Lastly, we came to the "humanoid robot" exhibition area can be said to be the highlight of the second floor
In the Western Zhou Dynasty, China's skilled craftsmen Yanshi developed a singing and dancing actor, which is the earliest record of robots in China. In the late Spring and Autumn period, China's famous carpenter Lu Ban, in the mechanical aspects of the inventor, according to the "Mojing" records, he had made a wooden bird, can fly in the air "three days no longer", reflecting the wisdom of China's working people.
Robots can accept human command, but also the implementation of pre-programmed programs, according to the principle of artificial intelligence technology to develop a platform for action, our museum is the first generation of robots, which has 17 degrees of freedom, and now the robot has been developed to 59 degrees of freedom, increased joint flexibility. Visible human intelligence and wisdom, in the field of robotics is not a full display and play?
Technology and humanities are integrated, nature and art echo each other.
