It is not only Boulter this spirited name, bolt also has "the arrow and the lightning "in English the meaning, perhaps is precisely so, in the athletic field we saw such one was not the coincidence: Before the competition starts, when introduces Boulter, he has made the archery movement; After the gunshot, he just likes arrow to the string, the diving posture, the lightning pushes to the front; In the final ten meters place, he decelerates unexpectedly, and turns head the full moon posture, pats own chest to celebrate the victory ahead of time.

它不仅是博尔特这个神气的名字，bolt在英语中还有"箭和闪电"的意思，也许正是如此，赛场上我们看到的这样一幕就不是巧合了吧：比赛开始前，在介绍到博尔特时，他做了个射箭的动作；枪响之后，他犹如离弦之箭，飞身而出，闪电般地一马当先；在最后十米处，他竟然减速，并以回头望月的姿势，拍着自己的胸口提前庆祝胜利。

避雷针引雷，强大的雷电效应对设备安全运行的威胁很大，避雷针、引下线、接地极的设计和布置直接影响设备运行质量。本文以ZQZ-AZ型自动气象站为例，讨论原防雷结构的不足，提出改进的办法。

The study indicates that:install MOA at line side is the most effectiveness method to protect banked switch,keep up the tower dielectric level will increase the probability of lightning stroke, but it can reduce the amplitude of lightning intrusive waves, this is advantage to the protection of the substation ,and lightning protective effect of this mode is the best.

研究表明：在开关前安装MOA是保护热备用开关的最有效措施，即使在最严重的情况下，热备用开关的绝缘裕度也超过10%，可以保护开关的正常使用；不增加进线保护段杆塔的绝缘水平会增加进线保护段的雷击概率，但是此措施可以降低入侵波的幅值，对变电所防雷有利，这种防护方式的防雷效果最好。
