逼近

In this paper ,on one hand ,we establish the weakly asymptotic order of the classical Bernstein interpolation sequence approximate functionin the Wiener space(or 1-fold integrated Wiener space),on the other hand,we discuss the asymptotically order for the average error of Lagrange interpolation sequence, Hermite-Fejer interpolation sequence and Hermite interpolation sequence based on the Chebyshev nodes on the 1-fold integrated Wiener space.

本文一方面确定了经典的Bernstein多项式算子列逼近函数时在Wiener空间(或1-重积分Wiener空间)下的平均误差的弱渐近阶；另一方面确定了基于第一类Chebyshev多项式零点的Lagrange插值算子列、Hermite-Fejer插值算子列和Hermite插值算子列在1-重积分Wiener空间下的平均误差的弱渐近阶。

Secondly, it is proved that the variable universe adaptive fuzzy control is asymptotically stable by use of Lyapunov theory.

在基于模糊系统泛逼近理论的自适应模糊控制研究中，主要做了如下工作： 1。

In MA models, the likelihood function is so complicated that we just search a better estimate value in a range. Another method introduced is autoregression approximation method.

在滑动平均模型中，由于似然函数形式很复杂，这里采用逐一搜索的方法，本文介绍的另一种估计方法是自回归逼近方法。

Furthermore,a quick way of selecting related parameters and a digital simulation of active band-pass filter single or two in series are given.

但理想带通滤波器仅在理论上存在，实际设计和应用的带通滤波器只能尽可能地逼近理想的带通滤波器。

The barycentric Lagrange interpolation collocation method for solving initial value problems of differential equation is introduced.

本文首先分析了重心Lagrange插值的基本性质，给出了采用重心Lagrange插值逼近任意连续函数的数值算法。

By use of ANN model trained under normal circumstance, inner and outer bus fault can be distinguished clearly. For the research on bus protection theory based on function approximation ability of ANN, it is crucial to establish the functional relation between the input and the output of bus protection object.

在研究基于ANN函数逼近能力的母线保护原理的过程中，首先就母线保护物理对象的输入输出之间的函数关系进行了研究，将物理对象的输入定为母线上各回路电流互感器传变后的同一时刻二次检测电流，输出定为母线上各回路的一次侧同一时刻流过的电流之和。

Example:The enemy warship tried to bear down on our small airboat.

敌舰企图逼近我们的小汽艇。中文意思：重重地落在。。。。。上

Cannot bear to see a bear bear down upon a hare.

我实在不忍心看着大熊一步一步向野兔逼近。

I can not bear to see a bear. Bear downs upon a hare.

我不忍心看着一只熊一步一步向一只野兔逼近。

So far the world has been spared a true water war, though the belligerency in Darfur comes close to being one, and competition for water can sometimes bring rivals together as well as drive them apart.

到目前为止世界已经躲过了一场水战，尽管交战状态正在逼近达尔富尔地区，但谁的争夺可以使对手走到一起，也可以是使他们更加疏远。

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.

交际能力和语法的关系应该是目标与途径的关系。
