The National Ignition Facility (NIF)--if it works as advertised, which is by no means certain given all of NIF's problems (see main text)--will pump almost 2 million joules of laser energy into a BB-sized pellet of hydrogen. But the bigger question is whether the pellet will actually achieve ignition--that is, undergo a sustained nuclear reaction that gives off as much energy as was put in? Most scientists on the project are cautiously optimistic, but others have grave doubts.
国家点火装置（NIF）——如果它能按预期工作，考虑到 NIF 存在的所有问题（见正文），这并非是确定无疑的——将把将近 200 万焦耳的激光能量注入一个 BB 大小的氢球。但更大的问题是，这个小球是否真的能实现点火——也就是说，是否会发生持续的核反应，释放出与投入的能量相当的能量？该项目的大多数科学家对此持谨慎乐观态度，但也有一些人对此深表怀疑。
