When blanket is designed, some necessary data, including tritium breeding ratio, irradiation damage ratio, intensity of activation radiation, magnet and thickness of shield, can be get through neutronics calculation. All of that must base on heat load and neutron power flux of first wall and divertor plate. So, the preparative calculation is prformed for that.

在设计包层时，需要进行中子学计算得到氚增殖率、辐射损伤率、活化放射性强度、磁体及其屏蔽厚度的计算、核加热产生率和冷却系统设计和安排的必要数据，而这一切都必须先知道第一壁和偏滤器靶板的中子壁负荷和热负荷；为此作了必要的先行准备计算工作。

For safety purposes, the metal shield must be connected to earth ground because the metal mounting plate will be at the guard potential.

A lower prepulse high power density water dielectric self-breaking switch was investigated on Flash Ⅱ generator.

在西北核技术研究所的&闪光－Ⅱ&装置上进行了水介质多针自击穿开关实验研究，该开关由2个或4个开关间隙、1个预脉冲屏蔽板及其支撑结构组成。

It is found that the damage of the lines is mainly aroused by heat effect and electric force generated by impulse current circuit, and the effect is different between different current value and different lines. The steady state and transient state shielding efficiency of plate shielding cabin with metal silk net window and without window are measured, and the influence of window to shielding efficiency is analyzed. The result shows that the steady state shielding efficiency rises with frequency.

试验结果表明屏蔽室的稳态屏蔽效能基本上是随着频率的升高而变大，两种带合金丝网玻璃窗的金属板屏蔽小室的在10kHz以下时稳态屏蔽效能有15dB左右，在20kHz以上时各点稳态屏蔽效能都可以达到20dB以上，丝网玻璃窗对离窗近的测量点的屏蔽效能影响较大，而对离窗远的测量点影响较小。

2KV, and the critical disruptive discharge voltage of low voltage transformer, filter and relay is between 3. 1 to 10.2kV. The lightning current withstand characteristics of electrical lines in low voltage system is also tested.
