逼近

Based on approximation capability of neural networks and mean value theorem, a stable adaptive control scheme is proposed to control the implicit dynamic system with an uncertain nonlinearity.

针对一类隐含控制输入的非线性系统，引用中值定理并利用径向基神经网络的逼近能力，提出了一种稳定自适应神经网络控制方案，以实现对一类隐含控制输入未确定非线性系统的控制。

In the third chapter,two different methods which construct the Loeb measure are researched,and their consistency is proved.Next some basic natures of Loeb measurable function and Loeb integration have been discussed.

在第三章中，我们主要研究由确界法和内逼近法这两种不同的方法构造Loeb测度空间，并证明了它们的一致性，然后讨论了Loeb可测函数和Loeb积分的一些基本性质。

Count on this, the proportion of the medium income group in Shanghai is almost half of the total.

以此推算，上海中等收入人群的比例当逼近半数。

Its golden r ichness speaks not of the innocence of spring, nor of the power of summer, but of the mellowness and kindly wisdom of approaching age.

它的 金黄的浓郁，不是表现春的烂漫，不是表现夏的盛力，而是表现逼近老迈的圆熟与慈和的智慧。

When her husband climbed menacingly towards her, she threw herself out of the tree.

当他丈夫爬上树，面带怒容逼近她时，她纵身向树下跳去。

When her husband climbed menacingly towards her, she threw herself out of the tree , daring him to follow

当丈夫爬上树、面带怒容逼近她时，她纵身向树下跳去，看看丈夫有没有胆量也向下跳。

A meteorite was very close to them now.

一颗陨星正向他们逼近过来。

In this paper, a practical example was offered to analyze the feasibility of the new method by making use of saddlepoint approximation algorithm.

在此基础上，采用鞍点逼近算法进行了算例分析。

With the method of digital approximation, the zoom range of this optical system which meets two basic requirements is calculated out.

在此基础上，通过数值逼近的办法计算了该光学系统在外加电压作用下满足以上两个基本要求时可以达到的变焦范围。

We analyze and compare the advantage and the weakness of these two algorithms, and apply the second method to the approximation of tensor product offset surface.

文中分析和比较了这两种算法的优缺点，并将第二种方法推广应用于求张量积等距曲面的逼近。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.
