闭合曲线

[数] 封闭曲线

封闭曲线

1. closed curve arc：[数] 闭曲线弧

3. rectifiable closed curve：[数] 可求长闭曲线

If we have a closed curve then the line integral for work is just zero.

如果给定一条封闭曲线，那么求所做功的线积分为零。

And, I still want to compute the line integral along a closed curve.

但仍然想要沿着封闭曲线的线积分计算。

I need to be on a closed curve to do it.

我需要在一条封闭曲线上来做。
