有效函数

New algorithms and design strategies greatly imp- rove the XXX87's performance, lots of instructions can be finished in a few clock cycles. Newton-Raphson and Polynomial approximation are used to implement division, square root, and elementary functions.

特点是结合牛顿-拉夫逊迭代算法，采用多项式逼近法对初等函数、除法和平方根进行实现，既有效地利用XXX87片内的浮点加法单元和阵列乘法器，又避免了查找表的使用。

Python's builtin str function produces only 12 significant digits, and you may wish to use that instead.

Python的内置函数 str 只生成保留12位有效数字的浮点数，有时候你可以用它。

Nm and -4.86 kcal/mol respectively, which are in better agreement with experiment.

在MP2水平利用扩展的相关一致基组结合有效键函数，预言了Ro-o和ΔECP值分别为0.0923nm和-4.86kcal／mol，计算结果与实验值符合得很好。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
