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。

By singular value decomposition of the separating matrix, we present a novel independent-component-analysis -based contrast function for BSS, which is a generalization of the existing determined and overdetermined ones.

The subtropical ridge is expected to weaken later to provide room for increasingly poleward movement.

该副高将於稍后减弱，从而使 02W 路径之向北分量增加。

Nevertheless, the weakening ridge and the nearby 90W may serve to slow down 03W's westward movement, and in longer term poleward movement can be expected.

虽然如此，在 03W 东面的 90W 跟副高预期的减弱将使 03W 的向西移动分量减低，中长期将令该系统向偏北移动。
