| 摘 要： | 提出了材料表面接触电阻的测试方法，测试了几种典型材料的表面接触电阻；分析了材料表面接触电阻随压力的变化的规律。研究表明：材料的表面接触电阻是压强的函数。表面接触电阻是材料的固有属性，是材料本身的电性能所决定的，可作为材料屏蔽效能的衡量标准。

| Abstract: | The method is presented to test DC contact resistance of shielding materials' surface. By test of some typical materials, it is analyzed that the effects of force on DC contact resistance. The results show that metal surface contact resistance decreases with the increment of pressure. The resistance is mental nature property, which is determined by material's performance, and it can act as standard of material's shielding effectiveness. |
