To predict the slot film-cooing adiabatic effectiveness, a mathematic model was developed based on cohence non-isothermal jet theory.

摘要在伴温射流基础上发展了一种适用于缝槽气膜冷却绝热温比预估数学模型。

At the same time the required hypothesis of cohence and non-cohence between second-phase participle and grain boundary is also excluded when the model are worked out from the perspective of geometry.

同时，本文模型还避开了从几何角度推导模型必需子与晶界之间共格或共格假设。
