The shade would consist of individual craft around one metre across, put into position using a combination of magnetic launchers and ion propulsion.
遮阳天棚将由宽大约为一米的个体飞行物组成，并通过受到磁性发射装置与离子推进的综合作用而被定位。

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.
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。
