I had a great difficulty finding a job, so I went off to Livermore Lab to do controlled fusion plasma physics experiments.

我很难找到工作，所以我去了利弗莫尔实验室做受控聚变等离子体物理实验。

Now, some theories suggest phosphine gas or free-floating plasma orbs similar to those in plasma physics or some other naturally-occurring event, but to this day, still, nobody has an explanation for them.

现在，一些理论认为磷化氢气体或自由漂浮的等离子体球体类似于等离子体物理学或其他一些自然发生的事件， 但直到今天， 仍然没有人对它们做出解释。

So it's mostly at this point a question of understanding the properties of the plasma and the plasma physics, to be confident that that will scale as we build the larger version.

所以在这一点上， 主要是理解等离子体的特性和等离子体物理学的问题，以确信随着我们构建更大的版本， 它会扩展。

So fusion is all about plasma physics and understanding plasma and figuring out a way to hold your unstable, wily plasma stable enough for long enough that the fusion reactions will occur, and that's the big challenge of fusion.

所以聚变是关于等离子体物理学和理解等离子体并想出一种方法来保持不稳定、狡猾的等离子体足够稳定足够长的时间以便聚变反应发生，这就是聚变的巨大挑战。
