【摘要】 通过实验研究两相自然循环流动不稳定性脉动周期，建立理论模型，用理论分析法得到脉动周期的理论公式。用该公式计算的结果与实验值符合得很好。更多还原

【Abstract】 Oscillation period of two phase natural circulation flow instability is studied by experiment. A theoretical model is presented, and a theoretical formula of oscillation period is obtained with theoretical analysis method. The results calculated by the formula agree with experimental data quite well.更多还原
