摘　　要：本文对超临界压力锅炉的水动力特性进行了理论分析。通过对不同配置方式管组的水动力特性进行计算，指出在超临界压力下的大比热区（ｉ＝１７００～２５００ＫＪ／Ｋｇ）必须考虑水流的温度不均匀性对超临界压力锅炉水动力特性的影响。The dynamic characteristics of water in supercritical pressure boilers are analyzed theoretically. Through computation to dynamic characteristics of water for various arrangements of beiler pipings, it is important to point out that in region of large specific heat (i=1700～2500KJ/kg)under supercritical pressure, the influence of temperature nonuniformity of the water flow must be taken into consideration.
