美国加州劳伦斯·里弗莫尔国家实验室正在建造中的“国家点火装置”试图将１９２束激光射向悬挂在一个直径为１０ｍ的靶室中央、含有氘和氚、花生米大小的圆球靶上，靶丸可以是裸露的或封闭在金的圆柱体内。在前面的情形中，激光束直接射在靶丸表面。在后面的情形中，１９... The National Ignition Facility under construction at Lawrence Livermore National Laboratory in California attempts to direct 192 lasers to a spherical target containing deuterium and tritium and peanuts in the center of a target chamber suspended 10 m in diameter On, the pellet can be bare or enclosed within a gold cylinder. In the former case, the laser beam impinges directly on the surface of the target. In the latter case, 19 ...
