一个方程，这是相当于稳定的，一维不可压缩的雷诺方程，但它考虑到整个润滑油膜厚度的粘度变化，由于能量耗散内的膜。这表明，在润滑接触中发展的压力梯度降低的能量耗散的影响。该方程的使用说明了应用它在连续变形过程，如带钢轧制和带材和线材拉拔的入口区的分析。分析表明，热效应在决定这种接触的润滑膜厚度方面起着重要作用。
An equation which is equivalent to the steady, one-dimensional incompressible Reynolds equation but which takes account of viscosity variations across the lubricant film thickness due to energy dissipation within the film is developed. It indicates that the pressure gradients developed in a lubricated contact are reduced by the influence of energy dissipation. The use of the equation is illustrated by applying it in the analysis of the inlet zones of continuous deformation processes such as strip rolling and strip and wire drawing. The analysis indicates that thermal effects play an important role in deciding the lubricant film thickness in such contacts.
