结果表明，等离子体在壁处的反射系数约为0.59，变换工作气体后，在第一次放电的等离子体中，由壁释放的同位素含量约占65％。

The results show that the reflection coefficient near the wall is about 0. 59, and in the plasma of the first discharge after a gas change, the wall-released isotope amount to 65% .

充电电压和放电反峰系数的增大使发热和介质内应力加剧，可以使寿命缩短90%以上。

The increase of charge voltage and discharge inverse peak factor make the life of MLC over 90% shorter by enhancing both heat production and internal stress of the dielectric.
