这两个发明者称他们的想法为“捷希凯”，就是用激光激发的同位素分离。
The inventors called their idea Silex, for separation of isotopes by laser excitation.
这也许意味着，激光器每秒就可以发射10次，而且可以在半空击中落入聚变室的氢同位素靶丸。
That could mean firing the laser 10 times a second, at fuel pellets that are shot mid air as they are dropped into the fusion chamber.
美国国家点火装置（简称NIF）耗资35亿美元，建在一个十层楼高的建筑里，占地面积有三个足球场那么大。 它将利用激光把氢同位素靶丸转化为热核能量。
The $3.5bn National Ignition Facility (NIF) sits in a 10-storey building covering three football fields and will harness the power of lasers to turn tiny pellets of hydrogen into thermonuclear energy.
