| 摘 要： | 油品中的电荷遵循指数衰减规律,测出油品的相对电容率和时间常量,即可求出油品的电导率.通过电容比较测得油品的相对电容率,用放电过程电位的测量间接获得时间常量.采用静电自动测量系统采集数据,利用软件拟合出衰减曲线.该方法适用于电导率低于10-11S/m的油品测量.

| Abstract: | It is known that the static electricity follows the exponential attenuation law with time,so the electrical conductivity could be gotten as soon as the relative inductivity and the time parameter are measured.The relative inductivity of oil was obtained by comparing the inductivity,and the time parameter was given indirectly by measuring the voltage in the process of discharging.The electrostatic automatic measurement system was adopted to data collection,and the data was fitted one curve.The method mention... |
