2.Furthermore, it could accelerate the reform of other fields in China.
3.The initial development of explosive field and the circleflow behavior, the entire spread court, with an obstacle around an explosive source was obtained and the law of shock wave around-flow was analyzed.
4.By the accurate measuring to the voltage across the standard resistor,it can be known whether the DC substitution power of each range of the 1805B RF control unit meets our demands. Finally,the range of DC voltage corresponding to DC substitution power is provided.
