院士为科研拿自己做实验 身体注入7.1万伏静电(图)
2017-05-05 07:41:51 中国青年网
在大量实验数据基础上,刘尚合首次提出了“信号自屏蔽——电荷耦合”动态电位测试原理,并和同事们一起成功研制出静电电位动态测试仪等5种仪器。经过反复理论推算和仪器精密实验后,刘尚合得出的结果高于英美专家认定的数值。
如何才能证明自己推测结果的科学性?只靠理论计算显然不行,动物皮毛实验又能否达到人体的效果?为了尽早打通科研瓶颈,刘尚合大胆提出对人体直接进行高电压实验,并提议由他自己亲身来完成。
实验如期进行。助手们通过专门仪器,让电压从2万伏起步进入刘尚合的身体,他的头发、汗毛一根根竖了起来。4万、5万……已达到国外资料认定的最高值。助手们停了下来,但刘尚合却毫不犹豫指挥下令:继续加压。5.5万、6万、7万……静电电位测试仪的荧屏上显示,他身体上的静电电压已经达到7万1千伏。刘尚合一边紧盯着仪器,一边镇定地指挥着助手,同事们的心都提到了嗓子眼儿。
这是一个可以载入史册的时刻——人类首次测定并验证了人体静电电位的极端值!
弹药火工品在储存和运输过程中存在突燃突爆的“反常发火”现象,是困扰世界军事领域几十年的一道难题。由刘尚合主持的“弹药防静电理论与技术研究”项目,一举获得了国家科技进步一等奖。就这样,一次次无畏面对挑战,一项项成果相继问世,刘尚合也一步步登上国际静电研究领域的高峰。
“在与静电较量的路上,我从未想过放弃。”今天,刘尚合带领着落户军械工程学院的电磁环境效益国家级重点实验室,不断迈向新的征程。
