摘　　要：润滑油液经长时间使用后,会因受污染而使介电常数发生变化。为此,应用平行板空气隙电容器测定润滑油液的介电常数来确定润滑油液的变质程度,从而判断是否可继续使用,使传统的按期换油改为按质换油,并使润滑油液获得合理的使用效果和使用寿命。After being long used, the parameter ε of lubricating oil will change by pollution. This article introduces a parallel board with air interval to measure the degreement of the change of ε , and then to determinate its usable time limit, which can alter traditional oil-changing by time into oil-changing by its quality and can get the best use of its effect and life-span.
