Comparing with existing solutions, new method can utilize generators' speed signal measured by wide area measurement systems directly and detailed model and parameter of power system components were not needed. After sphering measurement-data, ICA with maximal negentropy criterion was carried out to obtain feature matrix. By this means high-dimension data of multi-machine perturbed trajectories were reduced to lower dimensions, and coherent generator groups were identified by pattern recognition consequently. Simulation results of 36-bus system with 8-generator and planning northwest China 750 kV power grid show that noise signals and bad data can be eliminated. This method is accurate in identifying coherent generator groups.

与现有方法相比，这种方法不需要获得系统元件模型和参数，而是直接球化广域测量系统(wide area measurement systems，WAMS)提供的发电机电角速度信号，再利用最大负熵准则进行独立分量分析得到特征矩阵，将高维数的多机受扰轨迹数据变换到低维空间，通过模式识别得到分群结果。8机36节点系统和西北750 kV电网规划系统算例表明，该方法能有效消除噪音和坏数据的影响，准确识别出同调机群。

The modular design of printNet system is divided into several application part, such as data processing tools, design tools, products, Business card printing tools, and solutions to technical tools, of which the highest is a design tool over the actions that it printLayout from page formatting and setting variables, but also can be used by an operator in a transform tool programming, so that the contents of the variables in a database in output for operations, now produetion of mostly to one-dimensional bar codes and encrypted bit or anti-false, the party is a method in the bar code by addition, subtraction, multiplication, Division, opinins Mo, and so after the results or the results of data, or the result is converted to the data that corresponds to a location in one of the ntehs detection accuracy is valid, just make a bit of the inverse operation, the operation that results in comparison with the original data, such as the same as the data is valid, such as different then the data is not valid, this scenario is the most simple and most primitive anti-counterfeit. PrintNet software to complex product environment " interpuntion and output the integration of integrated management " solution possible.

printNet系统的模块式设计分为几个应用部分，如数据处理工具、设计工具、产品制卡工具以及方案解决工具，其中技术含量最高的是对设计工具printLayout的操作，它除了设计页面格式和设置变量外，还可由操作员在转换工具中编程，以便对数据库中的变量内容在输出时进行运算操作，现在生产中应用的大多是给一维条码加校验位或是防伪加密，其方一法是将条码中的数据经过加、减、乘、除、取莫等运算后，将结果或将结果中的几位至于数据后，或将结果转换成对应符号放在数据中的某个位置，如须检测某一数据是否准确有效，只要把校验位上的数进行逆运算，把运算结果与原数据比较，如相同则数据有效，如不同则数据无效，这种方案是最简单最原始的防伪加密的方法。printNet软件系统使得在复杂产品环境下的&排版与输出一体管理&的集成解决方案成为可能。

Andrew Bogut's number, the name of the cheering section he created,"Squad Six" and his ranking in single-season block totals as his 175 put him behind Karem Abdul-Jabbar (238 and 212, 1973-74 and 1974-75 respectively), Elmore Smith (238, 1975-76), Harvey Catchings (184, 1980-81) and Alton Lister (177, 1982-83) in the franchise record books.

– 安德鲁·博古特的球衣号码，他的助威方阵&六之队&的名字以及雄鹿队史单赛季总盖帽数的排名—他本赛季的175次盖帽使他在特别的记录书上排名仅次于卡里姆·阿卜杜尔-贾巴尔（238次和212次，连续1973-74赛季和1974-1975赛季），埃尔莫·史密斯（238次，1975-76赛季），哈维·卡钦斯（184次，1980-81赛季）和阿尔顿·李斯特（177次，1982-83赛季）。

The combinatorial coding number of 64 codons to encode 20 amino acids and the terminate code is very huge.

用N个密码子对m个编码对象进行编码的编码格式是m元N维空间中的一个顶点。64个密码子对20种氨基酸和终止密码子进行编码格式的组合编码数是一个十分巨大的数字。

On the Web, one-sentence links are as legitimate as thousand-word diatribes—in fact, they are often valued more.

在万维网上，一行链接与数千个字的长篇大论一样有效──实际上往往链接更有价值。

Between 42 and 37 BCE Virgil composed pastoral poems known as BUCOLIC or Eclogues ('rustic poems' and 'selections'), spent years on the GEORGICS (literally,'pertaining to agriculture'), a didactic work on agriculture, and the cultivation of the olive and vine, the rearing of livestock, and beekeeping.

42和37组成公元前维吉尔诗称为田园牧歌或 Eclogues （'乡村诗'和'选择'），花了数年时间对GEORGICS （字面上看，'有关农业'），一个教学工作的农业和种植橄榄和葡萄，饲养牲畜和养蜂业。

Even before the edemas developed, Wawruch noted in his diary that he treated an outbreak of pneumonia months before Beethoven's death with salts containing lead, which aggravated what researchers believe was an existing case of lead poisoning.

即便在水肿扩展前，瓦维鲁克医生在其日记中写道，自己在贝多芬死前数个月用含铅盐水给他治疗过肺炎，研究人员相信这使得贝多芬的病情加重，最终因铅中毒而死。

Firstly, the binary watermarking image is converted into a one-dimension sequence. Then the audio signal is enframed into several segments.

On the basis of analyzing and calculating transverse tooth profile for geometry, the symmetry line and tip arc of transverse tooth profile for a teeth of gear were defined and it also be drawed out.

由于渐开线圆柱齿轮的端面齿廓为渐开线，而且轮齿的厚度与齿轮的模数相关，所以用AutoCAD建立渐开线圆柱齿轮的三维模型十分困难。

The split between the two groups can hardly be papered over.
