摘　　要：针对国产引进型300 MW汽轮机排汽通道存在的问题,论述了对其改造的必要性并提出了改进措施.而改造之前的风洞试验及改造后的效果测试,都是排汽通道改造成功与否所必需实施的,因此,推导了这2个试验的理论依据,以供此类科研和试验人员参考.According to the existing problems of domestic 300MW turbine exhaust passage,the necessity of transformation is discussed and the improvement measurements are proposed.The wind tunnel test before transformation and the effect test after the transformation must be carried out no matter whether the transformation of exhaust passage is successful.This paper deduces the theoretical basis of the two tests which can be as a reference for researchers.
