It has been shown that when the RF frequency is less than the ion plasma frequency, the ionflux density will strongly depend on the time.
结果表明，当射频场的频率小于或等于离子等离子体频率时，离子流密度明显地随时间变化。

Our results indicate that there exist the differences of ionflux and dose among the inner, outer surfaces and the end surface of the bore.
计算机模拟结果显示了空心圆管内部、外部及端点表面处的离子流密度分布和注入剂量分布存在很大差异。

Some numerical results have been obtained for the instantaneous sheath thickness, the instantaneous voltage and the ionflux density on the substrate, etc.
