Their antistatic performances were determined using methods of electrification voltage by friction and surface density of charge 采用摩擦起电电压法和电荷面密度法，对其进行了抗静电性能测试。

Experimental results indicated that surface density of charge of the acrylic fabrics contained 7 . 68 % of the stainless steel filament decreased by 96 . 11 % as compared with the pure acrylic fabric 与纯腈纶织物相比，加说7 . 68 %不锈钢长丝的腈纶织物的电荷面密度降低96 . 11 % 。

This paper intends to illustrate by the calculation of concrete examples that conductors are different in their electric charge intensity although they are identical in their surface curvature 摘要通过具体实例计算表明，在静电平衡的条件下导体表面虽然曲率相同，但电荷面密度却不一定相同。
