| 摘 要： | 运用传热学基本原理进行理论分析,得出了顺流及逆流的单相流流动以及含有相变过程的两相流流动温度沿程变化规律;归纳了冷热流体沿程温度变化曲线斜率的特点,证明逆流流动温度沿程变化曲线的凸凹形状取决于比热容和流量乘积的相对大小.

| Abstract: | The temperature changing rules of counter and parallel flow, including phase changing flow are given after theoretical analysis using the principle of heat transfer. The characteristics of the shape of temperature changing curves are summarized. It is concluded that it is the product of specific thermal capacity and flux that determinates the shape of temperature curve. |
