提出冷冻干燥升华过程主要由传热控制和传质过程两阶段组成。
This paper proposed that there are two stages in sublimation process: the heat transfer controlled stage and the mass transfer controlled stage.
认为番茄冻干过程为传热控制，建立了辐射边界的准稳态模型，利用该模型可以较准确的预测升华干燥的时间。
The freeze drying model on the basis of heat transfer processes for tomatoes subject to radiation boundary conditions was founded to predict the time of sublimation dehydration.
推导了界面上具有耦合传热时的控制体离散方程序，界面上的辐射热流以附加源项的形式出现在离散方程中。
The discretion equation was derived for the control volume with conjugate heat transfer at its interface, with the radiation heat flux at the interface appearing as an additional source term.
