摘要
改进单头单头螺杆泵定子端面线型，使其密封腔耐高压、防泄漏或少泄漏输送液的构想显然存在；但原文献在推导内凸圆弧轨迹方程时似出现差错，现提出纠正意见。
Abstract The idea of improving stator end surface lincar of simple screw pump and making its sealing capavity pressure tight,leakproof or loss leakage of transmission liquid is obviously in existence;but error seems to appear while derivatinginternal convex,circular are track equation in original text,now put forward correction opinion for identification and application by personnels at the same trade.
