摘　　要：针对最小二乘法辨识叶片泵定子内曲线存在无法确定理论过渡曲线准确位置的缺点，提出了一种辨识曲线轨迹的新方法──残差分析法，解决了最小二乘法不能解决的问题，同时对高压叶片泵的大半径圆弧的包角提出了新的观点．Aimed at the defect of inability to determine accurate position of theoretical transition curves of the inner contour of vane pump stator by means of least square method, a new trace identification method- residual error analysis method is proposed, which can deal with the problem that the least square method cannot. In the meantime, a new viewpoint concerning the subtended angle of the arc with large radius in high-pressure vane pump is advanced also.
