摘　　要：从反应堆堆芯部分的物理和热工水力实际过程出发，经过简化建立了１０ＭＷ高温气冷堆堆芯的具有分布参数的非线性的动态数学模型，并采用多重网格算法研究了在典型工况下堆芯的动态响应特性。计算结果表明，在额定工况下模型的稳态结果与设计数据相符合，动态结果也符合基本的物理规律。由于缺乏同类反应堆动态数据，动态结果需要进一步校验。The reactor core's physical model and its non liner mathematical model with distributive parameter on the basis of actual physical thermotics procedure of reactor core are established.The later is simplified and is used in dynamic simulation. The dynamic characteristic of reactor core in typical situation by multigrid method is studied. The result indicates that the stationary result of model corresponds with initial design of HTR 10 and the dynamic result also satisfies basic physics law. Since lack of dynamic data of same kind of HTR 10, the dynamic results need to be verified in the future.
