Abstract<正> 关于一般叶栅的繞流問題,現有的許多解法,如格利克(Garrick,J.E.)、馬特波尔(Murterperl,W.)和波略霍夫()等法,都以直綫叶柵的繞流問題为基礎。这些方法有个共同缺点,就是当叶片弯度較大时,計算甚繁而不准确。針对这个缺点,本文給出一系列曲綫叶棚的准确解,所用的保角变換和一般直线叶柵的保角变换一样簡單,可用來代替上述各法中的直綫叶栅部分,使它們适合于弯度較大的叶片;因为变換簡單,同时又有四个参数,故可用來調整叶棚的稠度、柵角以及叶片的進出口角度。本方法可用來計算叶柵中叶片的相互位置和形狀,尤其是弯度对于叶栅性能的影响,同时这些准确解可用來鑑定渦旋分佈法所給曲线叶棚近似解的准确度。我們应当指出:本方法所給的曲緣叶柵当稠度較大时,棚角有一定限度,所以只适
