聚合物基复合材料把无机物的高模量、尺寸稳定性以及光、电等特性与高分子材料的韧性、易加工性、电绝缘性巧妙地结合起来。

Polymer based composites combined the good process property, electrical insulation and toughness of polymer with the properties of inorganic materials, such as high module, good dimension stability.

与四点同线探针法一样，如果样品电阻和电压表的绝缘电阻（电压表的公共端到地）是同一数量级的，就可能需要使用差分测量。

As with the four-point collinear probe method, a differential measurement may be required if the sample resistance is of the same magnitude as the isolation (meter common to ground) of the voltmeter.

仪表地与面板，安全地要绝缘。

Instrument area and panel, safety area should be insulated.
