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。

At last , some investgation is made to change about elementary constant of the universe in today ,which demonstrates that elementary constant of the universe in today would change at a ratio of 2.3387723548904887*1050 per year which means that elementary constant of the universe in today would remain as an constant unchanged within one million years if its accuracy fix on the 4th digit after radix point of 7.7577806787995708*1060 As a reminder , both elementary constant of the unvierse elementary constant of the unvierse in today have nothing to do with the cosmic constant introduced by Mr.

基本宇宙常数是一个变化的物理常数，其数值变化的速率为：2.3387723548904887*1050 ，与今天基本宇宙常数7.7577806787995708*1060 相比较，如果在保持今天宇宙常数的数量级不变的情况下将精确度选定在小数点后第4位，那么今天基本宇宙常数将在100万年之内保持不变。
