摘要： 对两相毛细泵环及其反向式蒸发器在启动和工作过程中出现的工质循环脉动现象进行了初步的实验研究。分析了引起脉动现象的原因，研究了反向式蒸发器中温度和压力的脉动情况；并得到了蒸发器的主要性能参数——输出压头在各种工况下的变化规律。

Abstract: The fluctuant phenomenon of fluid circulation appears in the starting and working processes of two-phase capillary pumped loops(CPL).This problem was preliminarily studied by experiment.The origins of the fluctuant phenomenon were analyzed and the fluctuant situations of pressures and temperatures in the inverted type evaporator were investigated.The variation regularity of the output pressure in the evaporator in different conditions were obtained.
