科学家们将通过此次实验来研究一种名为夸克-胶子等离子体的物质，它是宇宙大爆炸后极短瞬间形成超高能量密度。
The experiments will allow scientists to study a substance called the quark-gluon plasma, which existed in the fleeting first moments after the Big Bang.
日冕的电离气体（又叫等离子体）不仅非常炙热，而且异常稀薄，其密度还不到组成太阳主体的氢气密度的十亿分之一。
As well as being very hot, the ionised gas of the corona (called plasma) has a superthin consistency. It is less than a billionth of the density of the hydrogen that makes up the main ball of the Sun.
共振法缩短了离子引出时间，提高了离子引出效率，并且可以通过对外加磁场的调节来控制等离子体密度。
The RF method shortens the ion extraction time, and increases the ion extraction efficiency. It can also control the plasma density by changing the magnetic field.
