High-voltage insulation space-components are critical to the reliability of traveling wave tube amplifiers on satellite. Unlike in atmosphere, high-voltage components working in space can easily discharge due to insulation molding defects, which will lead to failure of amplifiers. We can solve these problems through adopting epoxy resin matrix composites as filler and applying vacuum-pressure injection molding technology for insulated molding process.

Organic synthesis chemistry is a very fast-growing discipline and it plays a very important role in chemistry. With the development of organic synthetic chemistry, organic synthesis device has also made greater development. At the same time, advances of organic synthesis device further promote the development of organic synthetic chemistry. This paper describes the working principle and system architecture of organic synthesis device and takes a case of di-n-butyl phthalate (DBP). At last, I foresee great prospect for organic synthesis

This paper mainly introduces Process Control comprehensive Experimental System Based on MCGS. The system is a small distributed control system. The host computer with Monitor and Control Generated System (MCGS) completes the simulating and monitoring of the controlled objects. And by RS-232/RS-485, it communicates with the slave computer which is made of Siemens PLC (S7-200). The real-time detected and controlled objects are temperature, pressure, liquid level and flow. The collected data are treated and some data of them are calculated by the way of PID operation in accordance with the specific requirements which results will control the actions of actuators. And in addition, the system can be easily combined into a variety of chemical experiments according to different needs. Practice has proved that the experimental device fully simulates industrial control field and it is simple operation and flexible structure, the experimental effect is good
