以盘形凸轮为例，提出一种用计算机编程实现平面零件实物三维几何数据获取以及模型反求的方法。

This paper took discal cam as an example to bring forward a method of using computer program to get 3D geometric data of planar part and make its model in reverse.

计算偏导数的办法没这么麻烦，因为我们有常规的方法，因此我们不需要通过定义去求偏导数。

And, we'll actually learn how to compute their partial derivatives without having to do this because we'll just have the usual methods for computing derivatives.

庆幸地是，有许多艺术家仍然求诸于传统方法来表达他们的创意。

Fortunately, there are many artists out there who still turn to more traditional methods of creative self-expression.

It could also say, what are the methods associated with the string, 1. I'm sure you can quickly graph it, but notice they aren't the same.

我们也可以说，与字符串1相关联的方法有哪些？,我相信你们可以很快的求出来，但是请注意这跟前面的。

It's useful to have the average acceleration, which you can find by taking similar differences of velocities.

平均加速度也是很有用的,你可以用类似方法,取速度的变化量求出来

Well I'm relying on the contract, if you like, that the manufacturer of square root put together, which is, if I know I'm giving it two floats, which I do because I make sure they're floats, the contract, if you like, of square root says I'll give you back a float.

好吧我能靠一些类似合约来保证，如果这么说你喜欢的话,其实就是当求平方根的方法,获得了两个我已经确认了是浮点数的数后,这个类似合约的东西就会保证，返回一个浮点数。
