As the main task of the second phase of the lunar exploration project in China, the "Chang'e-3" probe is the first time China's spacecraft has achieved soft landing and patrol detection activities outside the earth. A key step forward and back. The State Key Laboratory of Metal Matrix Composites (Shanghai Jiaotong University) has developed a variety of high-performance aluminum-based composite materials and components for the lunar exploration project in China, and successfully applied it to the mobile subsystem of the "Yutu" lunar rover and "Chang'e-3" "The optical system contributes to the development of national aerospace science and technology.

Walking mechanism is one of the key and difficult problems for the "Yutu" lunar rover to carry out lunar movement detection. The "Yutu" lunar rover will carry out inspection work on the lunar surface, and will face the test of harsh and complicated space environment and complex unknown topography. For example, the temperature difference of "day and night" exceeding 300 ° C will cause thermal stress and thermal deformation of components, When walking, it must bear various collisions, squeezes, friction, wear, etc. The mission of spaceborne optical instruments requires that they must have high resolution and stable optical performance, which requires that when the structure and device are optimized for design, the materials used must have sufficient dimensional stability and good rigidity. performance. In response to application requirements, the State Key Laboratory of Metal Matrix Composites has developed a variety of new aluminum matrix composites with characteristics of light weight, high stiffness, high wear resistance, impact resistance, and dimensional stability, which have broken through the key technical difficulties in the processing process. , Successfully equipped with a variety of telemetry and remote sensing instruments on the "Yutu" lunar rover and "Chang'e 3", which provided a guarantee for the successful completion of the lunar exploration project.

The research team of the State Key Laboratory of Metal Matrix Composites has carried out long-term, systematic and in-depth basic and applied basic research on aluminum matrix composites. It has become the main research and development and manufacturing base of lightweight high-strength aluminum matrix composites in China, which is a high-tech in China. It has made important contributions to the development and maintenance of national security.

Coffee table is not only one of the most commonly used furniture, but also an ideal place to show your personality and unique style!

An indispensable space in the restaurant is a coffee table to feel the ritual of life and make time artistic and unique.

Considering the needs of customers who go to the coffee shop, we should pay attention to the leisure in the design of coffee shop tables and chairs. This is the reason why on the one hand, we require the beauty and artistry of the coffee shop tables and chairs, on the other hand, we require the coffee shop tables and chairs to be fresh, clean, elegant and fashionable. Modern cafes use dining room tables and chairs, in fact, a large number of design techniques are integrated into the modern style furniture design techniques.
