对于绳套型水位流量关系，常用连时序法定线，即：手工绘制水位流量关系曲线。通过实例介绍了利用三次样条插值进行绳套水位流量关系定线的方法，编写Matlab程序由计算机代替人工完成繁琐的手工作业，处理方法简单实用。误差分析表明，插值流量与人工推算流量的相对误差很小。

For determining the loop relation curve of stage-discharge,sequential method is commonly used,i.e,to manually draw the curve of stage-discharge. With an example,the paper discussed a practical and useful process determining the loop relation curve of stage-discharge based on cubic spline data interpolation. With a Matlab procedure,the computer did the tedious job which was normally done by hand. Error analysis shows that the relative error between the discharge calculated by computers and the discharge manually estimated is very small.
