| 摘 要： | 采用统一的方法对定态传热逆流和并流的平均温差进行了推导。推导过程无需假定冷热流体的特定流向,并利于得到对数平均温差“同侧相减”的规律。

| Abstract: | Mean temperature difference for countercurrent flow and cocurrent flow in steady continuous heat transfer has been deduced uniformly. In the deducing process, no specific flow mode is presupposed, and the conclusion of temperature subtracting by the same side for logarithmic mean temperature difference can be easily drawn. |

| Keywords: | temperature difference countercurrent flow cocurrent flow |
