“死光”是指一种具有极大能量的激光,即人们常说的激光武器。由于激光的亮度极高,甚至比太阳表面的亮度还要高一百亿倍以上,因而可以在百分之几毫米的范围内产生几百万个大气压和每厘米几万伏乃至更强的电场,能在千分之几秒甚至更短的时间内使那些难熔物质立刻熔解、气化。 “Death” refers to a laser with great energy, which is often referred to as laser weapon. Due to the high brightness of the laser, which is even more than a billion times more intense than the surface of the sun, several million atmospheres and tens of thousands of volts or more of electric field per centimeter can be produced within a few tenths of a millimeter , In a few seconds or even less time to melt those refractory substances, gasification.
