摘要
对用四种不同类型的粘度指数改进剂调制的几种多级油，在实验室中以1000s－1剪切速率作了流变性研究，并考查了40℃和100℃的粘度和粘度指数。对于多级油性能的评价，最重要的是要把其性能与测试时的条件相联系，而不能当作一个绝对的标准。
A few kinds of multigrade oils formulated with four kinds of different VI improvers were studied on rheological property within the limits of 1000s-1 shear rate in laboratory,and the viscosity and VI at 40℃ and 100℃ were investigated.For evaluating the property of multigrade oils,it is the most important to relate its property with test condition,can not be taken as an absolute standard.
