根据斐克分子扩散定理及能量、质量守恒原理，提出一种表面霜增长的简化模型。计算表明，模型与实验数据和其它结霜模型相当吻合，能够较真实地预估霜的成长规律。

On the basis of molecular diffusion Fick′s law and principles of energy and mass conservation,a simplified model of frost growth on a surface is presented.Numerical calculation shows that the model can predict the regularity of frost growth with reality.It is in accord well with existent experimental data and other theoretical models
