电阻率ohm-cm
电阻率（ohm-cm）是衡量物质导电性能的指标，单位为欧姆厘米。
在某些上下文中，它也代表了电阻的一种衡量方式。
具体来说，电阻率ohm-cm是描述物质在单位长度和单位截面积下电阻的数值。
要点如下：
定义：电阻率是描述物质导电性能的指标，单位为欧姆厘米（ohm-cm）。
意义：电阻率反映了物质在单位长度和单位截面积下对电流的阻碍作用。
影响因素：电阻率主要受物质本身的性质、温度、湿度等因素影响。
应用：电阻率常用于电子、电气等领域，用于制造各种电阻器、电容器等电子元件。
换算关系：在电子工程中，经常使用毫欧米（mho-in）或微欧米（uho-in）等单位来描述电阻率。
1 ohm-cm = 1000 mho-in，1 mho-in = 1000 uho-in。
总之，电阻率ohm-cm是衡量物质导电性能的重要指标，对于电子、电气等领域具有重要意义。
