The discharging current of the accelerator is measured with the Rogowski Coil,the discharging characteristic of the fast electromagnetic valve and the Ar-gaspressure in the coaxial plasma gun are measured with small piezo-electricpressure probes, and the velocity of the plasma in the coaxial plasma gun ismeasured with magnetic pickup coils.

使用压力传感器研究了所研制脉冲电磁阀门的时间特性，以及等离子体碎片加速器同轴枪内中性气体的压力分布；设计罗科夫斯基线圈并测量了本装置的放电电流；设计磁探圈并测量了同轴枪内等离子体的平均速度。

A hydraulic resistance instrument composed by two pressure transducers was used to measure the hydraulic resistance across the two kinds of channels. The impedance on both channels was measured by a four electrodes impedance instrument with 5kHz constant current. A vibration generator was put on one set of the channel to produce about 50Hz sound waves. The signal was detected by a crystal pickup on the other set of the channel to examine the transmission of the wave along the two kinds of channels.

使用双压力传感器流阻仪对两种通道的流阻进行测定；使用5kHz恒流四电极方法对两种通道的阻抗进行测量；使用激振器在通道的一端产生一个约50Hz的振动，在通道另一端用晶体拾音器检测振动信号，对两种通道的声音传导特性进行了测定。
