摘　　要：通过对乳化液在不同油相浓度时的有效粘度的测量,获得乳化液当量粘度系数的计算公式。在此基础上对扩展雷诺方程所进行的数值计算表明:即便使用油相浓度很低的乳化液,在润滑入口区也可能形成“油池”,从而改善润滑效果。The computing formula of equivalent viscosity coefficients of emulsions was obtained, by measuring the effective viscosity of emulsion with various oil fractions. On this basis, the numerical calculation of the extended Reynolds equation shows that： even the emulsion which oil fraction is very small,it is possible that the ＂oil pool＂ appears at the inlet zone of lubrication, and lubrication effect has ameliorated.
