摘要
分析了矩形平板下冰在压力与温差共同作用下产生的熔化过程。利用接触熔化理论求得压力分布、熔化边界层厚度、作用力与熔化速度关系的表达式，进而分析和得到圆形平板下冰熔化的结果，并分别与压力、温差驱动熔化的结果进行了比较。
The contact melting processes of phase change material (the ice),which caused by the temperature difference ΔT and pressure difference Δp under the rectangular flat plate,are studied.Theoretical formulas of the thickness of liquid layer,the relationship between the melting velocity and exerted force during the melting are obtained.The related results for the circular flat plate are also derived.After comparing with the results for the ΔT driven and Δp driven melting,respectively,some useful conchusions are drawn.
