Third, gas leaks, including helium from the spacecrafts' radioisotope thermoelectric generators has been viewed as possible causes.

第三，气体泄露，包括探测器的放射性同位素热电发生机泄露的氦也被视为一种可能的原因。

"The lunar regolith is abundant in helium-3, a clean fuel that may support the earth's energy demands for more than a century," she said, admitting that there is still a long way to go from the probing of the element to its actual use.

月球regolith丰富的氦-3 ，清洁燃料，可支持地球的能源需求，为一个多世纪以来，她说，承认这方面还有很长的路要走，从试探的元素，其实际使用。

Then the paper deduced the quench development characteristic of MgB2 tape by all the above study. The work environment cooled by GM cooler is an adiabatic environment. However the environment cooled by liquid helium is incomplete an adiabatic environment. In order to simulate the adiabatic environment, the tape was remodeled as follows. The tape is bundled by vitreous riband in half pile mode, and the angle of the tape and the riband is 45 degree. Then use cryogenic epoxy hardener to coat the surface of the riband.

上述的三个工作环境中，制冷机传导冷却工作环境是绝热工作环境，而后两者并非是绝热工作环境，为了模拟带材的绝热工作环境，对带材作如下处理：用玻璃丝带对已固定好电压引线的带材以半叠包的方式缠绕一圈，玻璃丝带与带材成45度夹角，然后用低温环氧胶均匀涂抹在玻璃丝带的表面，随后用烘箱烘烤已涂匀环氧的带材18-24小时，最后取出带材直到低温环氧完全固化。

This work discusses and compares the methods of deriving the Rutherford scattering formula,and analyses the Rutherford scattering in the low energy(e,2e) reactions through the study on electron impact ionization of helium.
