摘　　要：利用电容器原理验证油液的污染程度,研究电容率与油液污染程度之间的变化规律.实验结果表明,水、酸值和金属颗粒是影响油液污染程度的重要因素,电容率法作为验证油液污染程度的方法是可行的.The capacitivity method was used to assess the contamination level in oil using the principle of capacitor,and the dependence of capacitivity on the level contamination was studied.The experimental results showed that water,acid value and metal particles were important factors affecting oil contamination,and capacitivity method was feasible to access contamination level.
