摘要
对汽油机油行车在用油硅胶－离子交换树脂法分离出来的酸性物质，用凝胶渗透色谱（ＧＰＣ）法定量分析了其中的羧酸类化合物，根据酸性物质的化合物类型及含量，可了解机油随行车里程增加而氧化变质的规律。
The acid fractions isolated from the used engine on by ion-exchange chromatography can be separated quantitatively into carboxylic acid groups with different molecular weight by gel permeationchromatography. On the basis of the compound types and contents of the acid fractions, the dependenceof the deterioration of engine oil on the mileage travelled by the test car was explicated.
