摘　　要：本文基于分岔理论及DERPAR数值算法,运用均相模型计算得出典型沸腾两相自然循环系统的静态分岔解图。讨论了系统压力、欠热度、阻力等参数对运行稳定性及输热能力限的影响。通过采用不同冷凝器模型,研究了冷凝模型与参数对流量漂移特性的影响。并将结果与漂移模型计算结果进行比较,结果可为两相自然循环回路设计、运行提供参考。Based on theory of bifurcation and DERPAR numerical algorithm, static bifurcation solution diagram of a two-phase natural circulation system is presented, using homogeneous flow model. Effects of such parameters as system pressure, sub-cooling, and pressure loss on flow excursion characteristics and transport capability of heat load are also delivered. Meanwhile, influences of condenser models and parameters on flow excursion instability are also studied. Furthermore, the results based on different models are compared, which may provide some references for the practical design and operation of two phase natural circulation loop.
