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。

Plasma (physics)
Plasma (from Greek πλάσμα, "anything formed") is one of the four fundamental states of matter, the others being solid, liquid, and gas. A plasma has properties unlike those of the other states.
A plasma can be created by heating a gas or subjecting it to a strong electromagnetic field applied with a laser or microwave generator. This decreases or increases the number of electrons, creating positive or negative charged particles called ions, and is accompanied by the dissociation of molecular bonds, if present.
