求翻译：该油品400℃和100℃黏度下降很大，黏度指数亦降至62,表明该油品无论是基础油的粘温性能，还是黏度指数添加剂的抗剪切性能均很差。特别是高温黏度的急剧下降，直接导致该轴承箱在工作温度下不能形成有效的润滑油膜，产生混合润滑甚至边界润滑，致使摩擦和磨损增加，因而润滑油温度增高。是什么意思？

400 ° C and 100 ° C viscosity of the oil drop large viscosity index to 62, indicating that the oil, base oil viscosity-temperature performance, viscosity index additive shear resistance is poor. Especially at high temperature viscosity of the sharp decline, a direct result of the bearing housing can

The oils are 400 and 100 ° °C C viscosity a large decline, viscosity index also dropped to 62, indicating that the oil is the base oil viscosity temperature performance additives, or viscosity index of the anti-shear performance is very poor. In particular, the sharp drop in temperature viscosity, l

This oil quality 400℃ and 100℃ the viscosity drops very in a big way, the viscosity index also falls to 62, indicates this oil quality regardless of is the base oil sticks the warm performance, the viscosity index chemical additive anti-cutting performance very is bad.Specially the high temperature

The decline in oil viscosity of 400 ° c and 100 ° c is very large, viscosity index also dropped to 62, indicating that the oil is the base oil viscosity-temperature properties, is also additive shear viscosity index performance is very poor. Especially sharp decline in high-temperature viscosity, le
