| 摘 要： | 由多个自然循环回路耦合而成的余热排出系统具有明显的非线性特性。本工作开发了高效的全局求解方法，通过计算程序实现该算法，并对计算结果进行验证。与采用嵌套点迭代的计算方法相比，新方法计算速度提高了1个数量级。

| Abstract: | The mathematical model of the residual heat removal system with multiple coupled natural circulation loops has distinct nonlinear characteristics. The global solution method with high efficiency was developed, implemented and tested. Compared with the original method which uses the nested point iteration procedure, one magnitude of calculation speed improvement is achieved. |
