灰蓝的上空,突然随着几声巨响,像打雷一般便下起了一阵紧似一阵的“暴雨”。这“暴雨”,就是人见人怕的“死雨”,是由一种高浓腐蚀性液体化学剂形成的。这是一场惨无人道的现代化学武器战争。凡是沾着“死雨”的人,必死无疑。综观二战前后发生在世界上的四次规模最大的化学战争,给人类带来的灾难,值得人们深思、警觉、反省…… Over the gray blue, suddenly with a few loud noise, like thunder in general will be up for a burst of tense “storm.” This “rainstorm” is a scary “dead rain”, formed by a highly corrosive liquid chemical. This is a tragedy of modern chemical warfare. Those who are stained with “dead rain” will die without any doubt. Looking at the four largest chemical wars that took place in the world before and after World War II, the disasters brought to mankind deserve deep thought, vigilance and reflection.
