| 摘 要： | 本文根据物理过程与数值计算结果的分析，探索微零重力场中平行通道热管启动融化特性在地面实验的方法，即将三维问题合理地分解成二个二维平面的融化过程进行实验，原理性的实验表明，这种方法可在重力场中测试观察无重力影响时的融化过程，实验结果与数值计算很好吻合一致．本方法可望用以研究这种平行通道热管在航空飞行中启动融化的特性，因而具有其重要意义。

| Abstract: | Based on the analysis of traansient conduction of composite systems with arbi- trary finite domains and numerical simulation, a ground experimental program was proposed to investigate melting in monogroove heat pipe under microgravity. In this program, two-dimensional experiments were employed to reveal the meltingcharacteristics of the complicated three-dimensional melting process in the heatpipe.The experimental measurements are in quite good agreement with both nu-merical simualtion and the prediction by simplified analytical model. |
