The dissertation analysis different measurement on channel frequency,different vibration signals sets and different location to form each ICA result.With regard to the failure diagnosis of the turbine generator operation,the study has explored the possibilities to detect the failure diagnosis source from the measurement signals.It has also provided sufficient analysis case for the application of separation to detecting failure source on the turbine generator.2.Aiming at the engineering application of overcomplete bases ICA,the dissertation has raised virtual channel on the new method of ICA.It take advantage of some testified knowledge to the constitution of ICA known as, together with other measurement signal to proceed ICA separation,which can increase frequency on the input signal.

分析了以不同测量通道数量、不同振动信号类型组合和不同测点位置组成输入信号的ICA分离效果,并对机组在故障状态下,从测量信号中分离出故障源的可能性进行了探讨,为ICA在汽轮机振动故障源分离方面的应用提供丰富的分析实例。2针对超完备基ICA的工程应用问题,提出附加虚拟通道ICA的新方法,利用某些已经具有先验知识的独立分量构成附加输入信号,与其它测量信号组合在一起进行ICA分离,达到增加输入信号数量的目的。

Seek advice from lucky data according to Ai Rui, chinese website amount achieved 1.919 million in July 2008, odd week visits what the user exceeds 5 ten million to have 8 independently; Of more than 1 ten million have 45; And amount of independent visit user also can amount to the website odd week that ranks 1000 300 thousand, accordingly, chinese network media grows end not only, and of unusually thick still shape " oxtail ".

The plant species diversity of 9 associations in the Oxytropis coerulea community of mount Wutai was studied by using richness index, Simpson index, Shannon-Weiner index and evenness index, respectively. The results indicated that: The quantity of populations and species in the community have obvious unevenness character, which leads to variation of λ. index and H' index among different associations. R1 and H' increase firstly, and then decline slowly with the increase of elevation, which reach peak value at 2100 while E1 index waves steadily with elevation change.

应用丰富度指数(R1)、Simpson指数、Shannon-Weiner指数和均匀度指数(E1)研究了9个群丛的植物种多样性,结果表明:种群数量及其种群内个体数量具有明显不均匀性,进而导致λ指数和H'指数在不同群丛间的变化,R1、H'指数随海拔高度增加表现为先上升而后缓慢下降,在海拔2100m处达峰值,E1指数则随海拔变化呈现不稳定波动。
