摘　　要：用最小二乘法拟合叶片泵定子过渡曲线的类型有一定的局限性,无法确定加工方向,甚至无法确定过渡曲线准确的理论方程。本文通过检测的叶片泵定子内曲线的离散数据和加工理论过渡曲线时形成的误差原理,提出了在辨识过渡曲线类型和加工方向时应注意的问题和新的鉴别准则。There is a definite limitation of identifying the style of transition curve for vane pump by least square method fit, being incapable of confirming processing direction and even exact theoretical equation of transition curve. Comparing the discrete data of detecting stator curve with the error principle of theoretical transition curve and cutting error in this article, a new differentiating rule is put forward and some problems in discerning theoretical equation should be considered.
