It includes steady calculation and transient calculation, and consists of revised single channel model, forced external disturbance model, two-phase boiling model and transient model.

模型分为稳态计算和动态计算两部分，包括修正的单通道模型、强迫外干扰力模型、两相沸腾计算和动态计算模型等。

On the base of thin film evaporation mechanism of the channel, a comprehensive heat transfer model for thermosyphon boiling in narrow channel is developed.

基于这种狭缝通道气泡底部薄液膜蒸发机理，建立了狭缝沸腾传热组合机理模型。

It is certain to avoid cooling point in the channel, in case some outflow with high boiling point condensate in halfway to affect quantitative results.

务必避免通道中有冷却点存在，否则会使一些高沸点流出物在中途冷凝而影响质谱定量结果。
