A major advantage of fluidised beds is that they provide a well mixed, high surface area, fluid-solid system which is useful for efficient reactions and heat transfer.

流化床的一大优点在于能产生一个充分混合的具有很大表面积的流体与固体的接触系统，这对高效反应和传热都很有用。

The supercritical fluid has the following unique characteristics: low viscosity, high density, better performance of flow, mass and heat transfer, dis solution and so on.

前言：超临界流体具有黏度低、密度大，有较好的流动、传质、传热和溶解性能等特性。

The experimental results showed that the high heat flux portions of heat transfer curves shifted to the left with elevating fluid subcooling and was independent of other factors.

实验结果表明：核沸腾传热曲线随过冷度增加而向左移动，与其它因素无关。
