中文摘要：

一个数学模型基于 Lucas-Washburn 方程被开发了在一个毛状的环探讨在毛状的高度，毛状的半径和热流动之间的关系。在接口的稳定性标准被把小不安介绍给毛状的循环的接口详细学习。作为后果推出的公式被用来在经历阶段变化的一个毛状的环分析毛状的灯芯和稳定性的高度的影响。

英文摘要：

A mathematical model based on the Lucas-Washburn equation has been developed to address the relationships between capillary height, capillary radius and heat flux in a capillary loop. The stability criteria at the interface are studied in detail by introducing a small perturbation to the interfaces of the capillary loop. The formulae deduced as a consequence are used to analyze the influence of height of the capillary wick and the stability in a capillary loop undergoing phase changes.
