This invention relates to MIMO test method in a multi-user MIMO radio communication system including: estimating the channel matrixes of all users at the base station, computing an orthogonal projecting matrix M of the interference matrix of each user and transmitting M to each user periodically, receiving data sent by the base station at the user end and getting the orthogonal projecting matrix M from the received data, transforming the MIMO test of a desired user to the minimum value of a K-element secondary convex function, in which, K expresses the number of sending antennas and getting estimation of the test data by a ball test method.

一种多用户多输入多输出无线通信系统中的MIMO检测方法，包括步骤：在基站估计所有用户的信道矩阵；计算每个用户的干扰用户矩阵的正交投影矩阵M，并将每个用户的正交投影矩阵M定期发送给每个用户；在用户端接收基站发送的数据，并从接收的数据中得到正交投影矩阵M；利用正交投影矩阵M将期望用户的MIMO检测转化为K元二次凸函数的极小值，其中K表示对期望用户而言，发送天线的个数；利用球检测的方法，得到检测数据的估计。

I'm using Windows 2000 operating system, as a result of misoperation previous, deleted a number of useful series of procedures.

我用的是Windows 2000操作系统，由于前几次的误操作，一连删除了多个有用的程序。

Problems that result from high-speed movement of the equipment in measurement unit, including image mistiness, repetition and skip, are deeply analyzed. And the processing time is tested. The result indicates that image processing algorithm is accurate, fast, and robust. The simulation result of fuzzy controller, which is gained through Matlab, indicates that the fuzzy control system can accurately determine cutter's number. The experiment of cutter indicates that the resistance thread can meet the demand.

分析了检测单元中装备高速作业带来的图像模糊和重复遗漏问题，测试了图像处理算法的时间，结果表明设计的算法准确、快速、适应性强；利用Matlab对模糊控制算法进行仿真，仿真结果表明控制算法能准确地确定刀具编号；切破刀具的试验表明设计的电阻丝刀具能满足要求。

After the problem of speech mixing in an 8-point video conferencing system is solved, three queue models of the SSMS are designed in order to make the choices of the buffer size and the prefetching packet number more reasonable so as to save the memory space and reduce the algorithm delay.

在解决了8点会议系统中的多路语音实时混合问题后，为了使得算法中缓冲区大小的选取和预取数据量的分配更加合理以节省存储空间及减小算法时延，本文建立了三个有关SSMS系统的排队模型。

While about 80 percent of parents use the MPAA's ratings system, the number drops precipitously for TV ratings, where as few as 39 percent of parents said they used them.

尽管80%的家长使用MPAA的分级系统，这一数字在电视分级上急剧下降，只有39%的家长表示他们使用这一系统。

ABSTRACT: By using image processing software, based on the coordinates of clear points in images and the theoretical coordinates of the points in the reference coordinate system, the coordinate relation multinomial of pre-and post-correction control points can be established by means of the digital image correction technique and the coefficient in the multinomial can be sought on the basis of the coordinates of a certain number of control points.

前言 考古绘图一直是考古学研究中不可或缺的重要技术，能够反映考古遗迹的分布状况或者典型器物的多重特征。但是随着考古学研究的深入和对相关技术手段需求的增加，考古绘图技术却始终停留在通过直尺等量取数据、再使用直尺和铅笔绘图的水平上，成图精度很低，周期较长，图形品种单一，远远不能满足现代考古学研究的需要。

This trend helps to increase the number of multisyllabic words,enlarge affixal words and morphemic syllables,and enrich the Chinese system with diverse word-formation patterns.

它们凭借极强的能产性构成了一系列的词族，对现代汉语词汇系统产生了巨大冲击，具体表现在：现代汉语词语多音节化趋势加强；促进了现代汉语词汇词缀化或音节词素化倾向；大大丰富了现代汉语构词的方式，致使构词方式多样化。

Our country has the air Dangerous shelf project the company for the number multitudinously, but truly has the air Dangerous shelf system design development, manufacturing capacity very few, the scale extremely is also limited.

我国拥有空气悬架项目的公司为数众多，但真正拥有空气悬架系统设计开发、制造能力的寥寥无几，规模也十分有限。

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。
