小波光顺时，通过丢弃细节曲线，保留近似曲线，既保留了原曲线的总体形状，又减少了控制点，最终达到小波光顺的目的。

The whole form of original curve is retained and control points is reduced with discarding detail curve and retaining approximate curve, so the target of fairness is reached.

这些金属都，特别脆弱，即使曲线，看上去非常近似-，它们都有这些特征-，那么这个点，将会一直呆在这里。

There are metals which are extremely brittle, and even though the curve - would look very similar — - it has all these characteristics — this point, then, would lie all the way here.

我们要画一张图，我们将看到是否，我们可以得到一条，与那条近似的曲线。

So we're going to plot it, and we're going to see whether we can come up with a curve that is somewhat similar to that one.

At any instant, your motion, if it follows any curve, locally can be approximated as being part of some circle.

在任何时候,如果做曲线运动,都可以近似地认为是圆周的一部分
