通过建立物理模型,得出了液膜排液速度与表面粘度的关系式,从理论上定性研究了表面粘度与泡沫稳定性的关系,并通过实验予以验证,实验结果与模型相符. Through the establishment of the physical model, the relationship between the liquid film drainage velocity and the surface viscosity was obtained. The relationship between the surface viscosity and the foam stability was theoretically and qualitatively verified by experiments. The experimental results are consistent with the model.
