摘要: 文献[1]得到了不可压缩理想势流绕两平行平板间圆柱流动的近似分析解.本文指出,用М.Е.Швец法[2]亦可得到与文献[1]完全相同的结果.如果用本文作者新提出的改进了的М.Е.Швец法[2]则可得到比文献[1]更加精确的结果.有算例.Abstract: In ref. [1], Lin obtained an approximate analytical solution of the ideal potential flow around a circular cylinder between two parallel flat flates.In this paper, the author shows that one may obtain the result coinciding with that obtained in ref. [1] by making use of the Shvez's method[2]. Morever, we can obtain a more accurate result than that obtained in ref. [1], if we make use of the improved Shvez's method[2]. Some calculating examples are presented.
