Nowadays both theoretical and experimental investigations have extended the concept of solitons to include the cylindrically and spherically expanding or contracting nonlinear waves displaying general soliton properties with the exception that their amplitudes are functions of the radial distance.

虽然目前，理论和实验研究已经扩展了孤子的含义，其中包括了在柱坐标和球坐标下进行展开或非线性波呈现一般意义上孤子的性质但振幅是半径的函数等。

The error source of CMM is complex, and the current main research is its geometric error. In the paper, 21 items of geometric error are measured accurately, simply and fast with the 2-D laser interferometer and four quadrants photo detector. The measurement gets rid of measuring so many lines and several diagonal lines in linear displacement method, and also solves the question that error measure of large-scale CMM can not be measured with 1-D ball array and ball plate conveniently.

坐标测量机的误差源纷繁复杂，当前主要研究的是其几何误差，课题中研究了一种采用二维激光干涉仪和四象限光电探测器相结合的测量方法，对三坐标测量机的21项几何误差进行了准确、简便、快速的测量，摆脱了线位移法测量直线过多且包含多条对角线测量的弊端，同时也解决了一维球列和球板不方便检测的大型测量机的误差检测问题。

After doing the statistical test, it shows that there is not obrviously differentiae among the coordinates transferred by the four methods. However, putting four-parameters and six-parameters methods into practice is easier than the others.

研究结果发现，四、、BPN倒传递神经网路及多变量复回归坐标转换成果，经统计测试四种坐标转换模式结果，并无显著性之差异发生，然而，在实用上则以四参数及六参数转换较为简易。

Hence, the speech contents are direct existence, and show themselves as if a speaker does not say them.

所言内容的"他"是指示主体，不但空间、时间关系以"他"为指示坐标，而且价值评判的坐标也是"他"。

Of course once things are in print they are likely to be disseminated.

但是，他只给了石家庄一个历史的、纵向的坐标，没有给一个现代的、横向的坐标，石家庄到底在世界上的哪一个角落。

Area coordinates and general Duffycoordinates are employed to transform the singular integrals of the Time-Domain Electric Field Integral Equation into non-singular integrals, which can be accurately and efficiently evaluated by dividing the transformed domain of integration into sub-domains.

摘要该文首先利用参数坐标和广义Duffy坐标变换将时域电场积分方程的奇异性积分转换成非奇异性积分，然后根据时间基函数的特点将该积分转换成可以快速精确计算的分区域积分。
