该 粘度指数是衡量多少温度变化作为石油的粘度变化。
The viscosity index is a measure of how much the oil's viscosity changes as temperature changes.
适用于树脂、油漆、涂料、乳胶、粘胶计、石油、洗涤剂……等物体的绝对粘度测量。
Suitable for resin, paint, paint, latex, adhesive, oil, detergent... Objects such as absolute viscosity measurement.
流体的运移性与粘度成反比，石油吸收部分气相组分后粘度降低。
The mobility is inversely proportional to the viscosity, and the viscosity is reduced when the oil takes up gaseous components.
