针对多孔介质内流动不稳定起始点特性进行了实验研究。研究结果表明：热流密度越大，系统稳定性越弱；入口过冷度对系统的稳定性影响呈非单调性变化。对实验数据进行回归处理，提出了含内热源多孔介质内不稳定起始点的计算公式。

The onset of flow instability (OFI) in the porous media with internal heat source was investigated experimentally .The results show that the higher the heat flux is ,the weaker the system stability is ;and the influence of inlet subcooling on system stability is non-monotonous .A new qOFI correlation was obtained by analyzing the exper-imental data using regression method .
