摘　　要：对两相自然循环流动不稳定性问题进行了机理性实验研究，系统压力范围为０．１ＭＰａ－０．４ＭＰａ。通过实验，分析了不稳定流动的机理，并根据其内在特性总结出两类主要的不稳定流动，为深入进行理论研究打下了良好基础。At present 'Flow instability of Two-Phase Natural Circulation flow' is an important topic in worldwide study. This paper deals with the mechanism research based on a series of experiments from 0. 1MPa to 0. 4MPa. Through detailed analysis a systematical instability mechanism is presented and two main kinds of unstable folw are defined.
