针对周盛、沈孟育文［５］中提出的论点．提出评述。认为：（１）文［２］中根本不存在什么所谓混淆跨音速流场基本属性的错误，这完全是文［５］作者的错误推论。（２）基于中心Ｓ２流面和任意回转Ｓ１流面迭代的三元流动计算是当前先进的轴流式叶轮机械设计方法。（３）Ｓ１和Ｓ２两族相对流面理论是当前先进的叶轮机械设计分析的理论基础。 For Zhou Sheng, Shen Meng Yuwen [5] in the argument. Make a comment It is considered that: (1) There is no such thing in the text [2] that the so-called confusion of the basic properties of the transonic flow field is completely erroneous inference by the author [5]. (2) The calculation of ternary flow based on the iteration of the center S2 flow surface and the arbitrary rotation S1 flow surface is the current advanced design method of axial flow impeller. (3) The relative flow surface theory of S1 and S2 is the theoretical basis of the current advanced impeller mechanical design and analysis.
