After affirming the existence of non-Fourier effect, the hyperbolic equation suited for describing rapidity heat transfer process inside propellant is obtained.
Based on the heat balance equation of snow surface and the periodic variations of temperature field and heat flow, the Fourier model of snow surface is established.
根据雪面温度域以及热流的周期性特点，在雪地表面热平衡方程的基础上，建立了雪面辐射温度的傅里叶模型。
