It's shaped like a doughnut, and it uses powerful electromagnets to suspend the super hot hydrogen plasma in a vacuum, keeping it stable and away from the walls of the machine.

它的形状像一个甜甜圈， 它使用强大的电磁铁将超热氢等离子体悬浮在真空中，使其保持稳定并远离机器壁。

So if you want to create a nuclear fusion power station, first you need to heat up hydrogen to more than 100mn degrees and find a way of keeping hold of the super hot hydrogen plasma to allow fusion to happen.

所以如果你想建造一个核聚变电站，首先你需要将氢气加热到 1 亿度以上， 并找到一种方法来保持超热氢等离子体以允许聚变发生。
