发动机冷却液折光率、冰点、密度均可与浓度进行关联,但目前通常使用的冰点与浓度之间不存在良好的线性关系,影响到浓度评定的准确性。分别研究折光率、冰点、密度与发动机冷却液浓度之间的关系,为准确评定发动机冷却液浓度提供依据,并讨论发动机冷却液浓度的测定方法。

The concentration of engine coolant is related to refractive index, freezing point and density. The relationship be-tween freezing point and the concentration is not so good that the accuracy of assessment of the concentration is affected. The relationship between refractive index, freezing point, density and concentration is respectively researched to provide a basis for accurate evaluation of engine coolant concentration. The determination method for engine coolant concentration is discussed also.
