利用频域方程对超薄液体(润滑剂)表面在压力和剪应力作用下的动力学行为进行了数值计算，并与用时域方程得到的结果进行了比较。对超薄液体(润滑剂)表面在正弦压力和剪切应力作用下的动态行为进行了频域分析，阐明了液体表面变形与应力频率和圆盘速度的关系。用时间域方程计算得到的正弦压力和剪应力引起的动力行为与用频域方程得到的结果逐渐吻合。
Numerical results were calculated for the dynamic behavior of an ultrathin liquid (lubricant) surface resulting from repetitively applied pressure and shear stress using the frequency domain equation and compared with those obtained using the time domain equation. Frequency domain analyses of the dynamic behavior of the ultrathin liquid (lubricant) surface produced by sinusoidally applied pressure and shear stress clarified the dependence of the liquid surface deformation on the frequency of the stresses and the disk speed. The dynamic behavior resulting from sinusoidally applied pressure and shear stress calculated using the time domain equation were found to gradually coincide with those obtained using the frequency domain equation.
