院士为科研拿自己做实验 身体注入7.1万伏静电

2017-05-05 06:31:46   解放军报

刘尚合与静电结缘于30多年前。1983年,在军械工程学院从事基础物理教学的刘尚合被国内外一连串由静电引发的伤亡惨剧所震惊。身为军人的刘尚合敏锐地意识到:“只有彻底攻克这一难题,追踪降伏静电这个‘幽灵’,才能真正确保武器弹药安全。”也就是那一年,刘尚合离开了奋斗10多年的半导体离子注入研究领域,踏上了追踪静电“幽灵”的科研之路。

在一无科研资料、二无试验设备、三不懂弹药原理的情况下,选择“静电与弹药”这一危险而又陌生的科研领域,需要多大的勇气?回忆起当年的选择,刘尚合说:“为探索未知领域,我愿意重当一名小学生。”

话虽这样说,但刘尚合永远不会忘记,那是一段怎样的艰难岁月:长时间处于超剂量有害气体和射线辐射的环境,让他的白血球值一度从正常的5000下降到2000;长期超负荷工作,让这个身高1米80的大高个儿体重锐减到60公斤……

鏖战近千个日夜,刘尚合在防静电危害研究方面终于初露锋芒:在国内首次提出使用物理和化学方法相结合的材料改性技术,一举达到国际先进水平;撰写的论文《聚合物材料防静电改性研究》在国际学术会议上一鸣惊人,专家们一致认为该项研究开辟了人类防静电危害的新途径。

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!
