有理函数

First, the scattering parameters of PT are transformed in to Y-parameters and equivalent "p" circuit model could be established. Second, vector fitting method is used to approximate admittances of equivalent "p" circuit model by rational functions. At last, a circuit synthesis method for rational functions is applied to build circuit model.

该方法首先将测量得到的互感器的散射参数转化为导纳参数并构建互感器的p形等值电路；然后，应用矢量匹配法对p形等值电路的导纳参数进行有理函数逼近获得它们部分分式和形式的频域表达式；最后采用电路综合方法构建出导纳元件的等值电路。

That theory is concerned with rational functions instead of just polynomials.

该理论所研究的是有理函数而不仅是多次式。

Hua's estimate is obtained for some Dirichlet character sums of rational functions.

对有理函数的特征和得到了一个估计，这个估计是华罗庚关于三角和的一个估计的类比。

Secondly, to solve some important nonlinear wave equations numerically, we establish various rational orthogonal systems with the Legendre weight.

其次，针对一些波动方程，我们构造了一些不带权正交的有理函数空间，并建立了相应的逼近理论。

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。
