从N S方程出发，得到了轴对称异型断面管纯剪切流动速度分布的一般解，进而推出了纯剪切流动有限宽度矩形断面管的速度分布和流量计算公式，证明了库特剪切流是有限宽度矩形断面管当宽度趋向无穷大时的一种特例。

Under this flow, the convex initial curve will preserve its perimeter, enlarge the enclosed area and make its curvature to be positive definitely. And as the time lasts, it will become more and more circular, and finally, as the time goes to infinity, the curve will converge to a circle in the Hausdorff metric.

本文证明在这种新的曲线流之下，闭凸曲线周长保持不变、所围区域的面积不断增大而曲率保持恒正，并且，随着时间的推移曲线变得越来越圆，最终当时间t趋向于无穷大时，曲线在Hausdorff度量意义下收敛到一个圆周。
