low ion meaning in English

低电离离子

It is found that the ablated surface morphologies for both the ti samples of different roughness have a similar change trend from roughening to smoothing with increasing the shot number , where the surface roughening is relatively weaker at lower ion current density
通过辐照不同原始粗糙度的纯金属ti发现，随着辐照次数的增加，烧蚀表面形貌均发生表面粗糙化向光滑化的转变。离子束流密度较低时，辐照表面的粗糙化程度较弱。
And production fashion is selected optional for assurance of the material character of hpch . the hpch material , in which the compound technique route of polybasic components is applied , has better properties such as high workability , high durability , low ion transference rate and so on
采用多组份复合技术路线配制出高工作性、高耐久性、低离子迁移率的hpch材料，对其宏观物理力学性能、耐久性能和微观结构进行了分析研究。
