Because the workpiece is in dynamic balance, the resultant moment acting on it should be zero. Introducing the moment from lapping tool and press head a moving differential equation is built. In this equation only workpiece rotating speed is unknown. It means that workpiece rotating speed can be got by this equation. Since there is a transcendental function in integral function of the equation an analytic result can not be got, only digital result can be got by a computer. Thus a change rule of workpiece rotating speed with lapping parameters is known, e.g. the radius of press disc ball socket, radius of press head ball, the distance between the workpiece rotating axis and lapping tool rotating axis, workpiece radius, modulus of elasticity of the press head and press disc, friction coefficients between the lapping tool and workpiece, and between the head and disc, pressure between the lapping tool and workpiece and pressure between the press head and press disc.

因工件处于动态平衡状态，其上所受到的来自于磨具和压头的力矩应相等，将二力矩表达式联立，建立工件运动微分方程，该方程中只有工件的旋转角速度是未知量，因此可以求出工件旋转角速度，但该方程积分式中含有超越函数，得不出解析解，只能通过计算机求出数值解，得出工件旋转角速度随各研磨参数的变化规律，如压盖球座半径、压头的球头半径、工件回转中心相对磨具回转中心的偏心距、工件半径、压头和压盖材料的弹性模量、磨具与工件间的摩擦系数、压头压盖间的摩擦系数、磨具与工件间的压强、压头压盖间的压力等。

Firstly,the cameras were calibrated high accurately,and the stereoscopic vision system model was established.Secondly,the 3D coordinates of the center of LED on the light-pen were achieved through matching the 2D images grabbed by the two cameras.Then,a series of the 3D coordinates of the center of LED were used for fitting straight line,and the 3D coordinates of the pen-points can be obtained from the line.

首先，对摄像机进行了高精度的标定，建立了双目立体视觉系统模型；其次，通过左右摄像机拍摄的二维图像，将两幅图像中的点进行匹配，获得光笔上的LED光斑中心三维坐标；然后，由一系列LED光斑中心的三维坐标拟合直线，从直线上得到笔尖的三维坐标。

In view of the existing problems of traditional resource allocating networks, a design method for RAN based on rough set and orthogonal least square was proposed. Firstly, rough set was applied to intelligent data analysis for extracting typical characteristics from the training samples, and then OLS was used to select best centers as the hidden layer nodes.

针对常用的资源分配网络存在的问题，提出了一种基于粗糙集和正交最小二乘的资源分配网络设计方法，通过粗糙集数据分析与处理提取训练样本中典型的数据特征，再结合正交最小二乘学习算法选取对输出能量贡献最大的数据中心加入到隐层节点。

In chapter 3,we dig out two families of invariant quartic curves of a quadratic system.

第五章讨论向量场具有对称中心的二次系统，利用系统的不变双曲线及不变四次曲线，我们确定了一个对应极限环（1.1）分布的二维参数区域，其边界的构成为如下几种常见的极限环分枝：霍夫分析，庞加莱分枝，同宿分枝和异宿分枝。

In p - benzoquinone solution with ethylene glycol as solvent,emission lines from PBQH'and R2 were obtained.

实验结果指出，在乙二醇溶液中得到苯半醌自由基和以碳为中心的自由基_2。

The aim was to establish a cultural centre in Jordan, called 'Darat King Abdullah II'.

目的是在约旦建立一个名为&达拉特国王阿卜杜拉二世&的文化中心。

Access to the catalytic center and an unusual switch I movement in the dimeric structure support this finding.

二聚体中催化中心的入口和一种不寻常的开关运动支持了这一猜想，即易位子复合物之间的相互作用或蛋白质前体的潜在结合位点都是由这种二聚体的结构特点决定的。

The results obtained revealed that:(1) the Pacific yellowfin has larger ring-radii as well as scale size than the Indian Yellowfin;(2) the specimens from the western Indian have larger value in scale size and ring-radii than those from eastern Indian;(3) there is a significant difference in the estimated growth curves between male and female for the Pacific specimens, but not for the Indian specimens; and (4) it is convinced that there are two yellowfin groups in the Indian Ocean, viz., one concentrates in the western Indian and the other densely distributes in the waters around Sunda Islands and Banda Sea; intermingling of these two groups is supposed to be occurred around 100°E in the season of northern summer.

3李氏现象在太平洋和印度洋都很显著。(4)年轮每年形成二次，时间为2～4月及8～10月。(5)有关成长的parameters如下：太平洋K=0.386 L=174.9 t0=0.05 东印度洋 K=0.278 L=212.7 t0=-0.19 中印度洋 K=0.290 L=215.6 t0=-0.01 西印度洋 K=0.349 L=191.1 t0=0.06 (6)由钓获率的分布、体长组成和其他生物学资料及以往之结果加以综合分析，显示印度洋的黄鳍鲔可分为东、西两个族羣，一为以班达海和小巽他羣岛附近海域为中心的东方羣，另一则以西部印度洋赤道流域为中心的西方羣。此两羣在100°E附近发生混合交流。当北半球的夏天时，此混合交流的现象较为显著。

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。
