The effects of pressure, mass velocity, inlet subcooling, heat flux, and exit throttle on the flow instability were determined in the modeling experiment. The thresholds of the flow pattern transformation instability and that of the density wave instability were obtained.

通过模型试验确定了压力、质量流速、入口过冷度、热流密度、出口节流阻力等因素对不稳定性的影响，得出了流型转化型和密度波型不稳定性的界限。
