discharge space meaning in English

放电空间

Further measurements for the deposited films indicate that the appearance and the deposition rate of the films also vary . after we simulate the magnetic field in such case with c program , these variations are owed to distributed change of magnetic field near the target surface and in the discharging space , which can influence the motion of charged particles in the plasma obviously
进一步对沉积薄膜的测量表明，薄膜的沉积速率等发生了变化，通过对空间磁场进行模拟计算发现，由于空间外加的纵向磁场引起了放电空间中以及靶面附近磁场分布的改变，影响了等离子体中带电粒子的运动并最终导致了上述变化。
