用电子自旋共振对国内几种典型合成油、基础油及加有添加剂的基础油，分别在不同温度下测定生成自由基的相对浓度，以及一定温度下放置一段时间自由基衰减情况，来考察导热油的热稳定性。
Several typical domestic synthetic and base oils and additive-added base oils were measured electron spin resonance at different temperatures to determine the relative concentration of free radicals and the decay of free radicals at a certain temperature for a period of time Heat-conducting oil thermal stability.
