本方法是利用了一些无因次参数及综合参数，使轴承负荷同柴油机工作过程及结构的某些参数联系起来。

This method utilizes some of non-dimensional parameters and combined parameters, in order to interrelate the bearing load with parameters of working process and structure of a diesel engine.

同时通过对气体压缩因子、黏度随压力、温度的变化，建立了这些参数和无因次压力的关系；

And based on the relations of compressibility factor and viscosity of the gas versus pressure, the relations of these parameters versus dimensionless pressure are also built.
