求翻译：The temperature dependence of the viscosity of a lubricant is typically characterized by the viscosity index (VI).1 The VI is determined using a standard method (ASTM D-2270) in which the kinematic viscosity of an oil at 40 and 100 °C is compared against the viscosities of two reference oils.是什么意思？ 待解决
