The goal, as its name implies, is to harness the power of the largest laser ever built to start "ignition" - effectively a carefully controlled thermonuclear explosion.

顾名思义，国家点火装置的目标是借助世界上迄今为止最大的激光器进行“点火”——有效且可控的热核爆炸。

The result, a thermonuclear explosion, is what destroys the target, but the entire three-stage process has to be mimicked if computers are to test weapon-designs reliably.

最终就形成热核爆炸，这也是摧毁目标的爆炸，但是如果计算机要非常可靠地测试核武器的设计，那么整个三个爆炸阶段都要被模拟。

Every 20 years or so the red giant star dumps enough hydrogen gas onto its companion White Dwarf star to set off a brilliant thermonuclear explosion on the White Dwarf's surface.

大约每过20年红巨星向它的白矮伴星上输出足够的氢气在白矮星表面产生一次耀眼的热核爆炸。
