在现代化学战中,所施放的化学药剂是一种能致命的气体。它无色、无嗅、无味,人不可能感觉到。现在还无有效的防御措施对付它。洛斯·阿拉莫斯国家实验室的研究人员已研制出一种探测系统。用一种廉价、常用的激光器很快就能探测出极其微量的损伤神经气体和所谓糜烂性气体的主要成份。把该器件结合到遥感系统中(或多半是低空飞行的飞机)就更为有效。化学战爆发后,用它探测武器装备上所吸收的残余化学药剂也能为幸存者提供某些防御。探测系统以脉冲持续时间为10毫微秒输出激光能量,照射被分析的样品。脉冲产生一种等离子体并把分子和粒子还原成它的基本的元素成份,它们发射出原子光谱,该原子光谱能 In modern chemical warfare, the chemical that is released is a deadly gas. It is colorless, odorless, tasteless, one can not feel it. There is no effective defense against it now. Researchers at Los Alamos National Laboratory have developed a detection system. With a cheap, commonly used laser, one can detect very minute amounts of the major components of damaged nerve gases and so-called erosive gases. Combining the device with remote-sensing systems (or mostly low-flying aircraft) is even more effective. After a chemical war breaks out, it can also provide some defenses to survivors by using it to detect the residual chemicals absorbed in weaponry. The detection system outputs the laser energy at a pulse duration of 10 ns and illuminates the sample under analysis. Pulses generate a plasma and reduce molecules and particles to its basic elemental composition, which emits an atomic spectrum that
