逼近

Based on polynomial-interpolation and curve-fitting theory, this paper presents a special feed-forward neural network using Jacobi orthogonal polynomial activation-functions, which exploits a group of order-increased Jacobi orthogonal polynomial functions as the activation-function of hidden-layer neurons.

根据多项式插值与逼近理论，以一组零阀值特例 Jacobi 正交多项式（第二类 Chebyshev 正交多项式）作为隐层神经元的激励函数，构造一种基于 Jacobi 正交基的前向神经网络模型。

When maximum jounce is approached, jounce force and energy are exchanged, at a first stage, with the jounce bumper cushion, then at a predetermined compression, jounce force and energy are exchanged, at a second stage, with the hydraulic jounce bumper.

当最大颠簸逼近的时候，颠簸力与能量在第一级与颠簸缓冲器垫交换，然后以预定的压缩量，颠簸力与能量在第二级与液压颠簸缓冲器交换。

It is predominant that this software engross a lot of system resources, and the track of the knifepoint can draw up the track of the drawing commendably.

本文采用的插补算法简便科学，只耗用相当少的系统资源，刀具轨迹能很好地逼近原图形轨迹。

We know next to nothing about the effectiveness of the alternative policies that central banks are forced to adopt if they don't just want to sit on their hand once the hit the zero lower bound: quantitative easing and credit easing, relaxing the collateral requirements for central bank lending etc.

如果一旦逼近零利率的边界，央行不想仅仅表示不赞成，他们会被迫采用其他的政策，譬如：增加货币量、放松信贷、降低向央行借贷的抵押要求、等等。对这些政策的效果，我们几乎一无所知。

Under the given level, this distribution function can pass the Kolmogorov criterion, thus it can approximate sample's real distribution function.

用这种方法构造的分布函数在给定的水平下可通过柯尔莫哥洛夫检验，从而可很好的逼近母体之真实分布函数。

First, the anthor gives a new algorithm of monad distribution function. Under given level, this distribution function can pass Kolmogorov criterion, thus it can approximate samples real distribution function.

首先给出了构造一维随机变量的分布函数的方法：用这种方法构造的分布函数在给定的水平下可通过柯尔莫哥洛夫检验，从而可很好的逼近母体之真实分布函数。

The objective function of the QP problem is a quadratic function which is an approximation of the Lagrangian function of the constrained problem and the constraints of the QP problem are linear approximation of the constraints of the constrained problem.

这些二次规划子问题的目标函数是原约束最优化问题的Lagrange函数的某种二次近似，其约束条件是原约束条件的线性逼近。

We also develope the corresponding spherical harmonic-generalized Laguerre polynomial mixed spectral method and apply them successfully to computation of three dimensional problems, exterior problems and nonlinear problems.

在第二章中，我们提出了一类新的广义Laguerre多项式正交逼近，其特点是适用于更多问题并能更好地拟合微分方程真解在无穷远处的性态，从而提高了计算精度。

"That cannot be," said the Lambkin,"I am only six months old.""I don't care."

狼不想再争辩了，龇着牙，逼近小羊，大声嚷道：你这个小坏蛋！

In chapter Ⅵ, we use local sampling method to approximate functions and geometric curves, and to find the solution of the Laplacian equation locally, several numerical results are presented.

第六章利用局部采样的方法来逼近函数和几何曲线以及求Laplace方程的局部解，并给出了几个具体的算例。

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。
