摘　　要：选取一个典型的自然循环回路,研究超临界压力下的静态特性,结合超临界压力下水物性特点,建立稳态分析模型,采用基于延拓的非线性数值方法求解,并对结果分析。同时讨论了入口温度、功率分布、管径、回路高度及入口阻力系数等因素对静态特性的影响。With establishment of a static model for natural circulation loops, and with considering the unique variation of thermo-physical properties under supercritical pressures, this paper, by applying appropriate non- linear numerical computation based on continuation concept, compute to analyze its static characteristics. The effects of such factors as inlet bulk temperature, power-type,diameter and height of the loops, coefficient of local resistance at inlet are also related as well.
