The first step requires cutting the claw of the claw, the purpose is to establish a good benchmark, in order to improve the accuracy of the correction, this step is best not to save.

第一步要求切削卡爪外圆的目的是为了建立一个良好的基准，以提高修正精度，这一步最好不要省。

The first algorithm gives unique result unaffected by the handling order of points concerned, and it calculates the control vertexes at once without estimation and correction.

第一种算法的特点是重建结果不依赖于顶点的处理顺序，不需要进行控制顶点的初估及修正，可使各控制顶点的计算一次完成。

In fact, this method is improper. The mistake results mainly from the following hypothesis: the first order correction of the heat conduction equation is tenable for all parameters in physics.

但事实上，这种方法是不妥当的，其错误主要来自于下述假定：对热传导方程的一级修正对物理学的所有参数都成立。

The VIX, a closely-watched gauge of volatility expectations for the next 30 days slipped under 13 for the first time since mid-2007 Friday, a signal that a correction is in order to some, but possibly an indication that not a whole lot is expected to change that drastically in the next month.
