某统计局欲了解第三产业总产出、中间消耗、增加值、劳动者报酬、生产税净额、固定资产折旧、营业盈余之间的关系，根据下面给出的数据建立相应的模型并进行分析，同时又因为变量数目过多影响对其的综合分析，要求对他们进行主成分分析；(Bureau of Statistics For a third of total industrial output, intermediate consumption, value added, workers compensation, production, net of tax, depreciation of fixed assets, the relationship between the operating surplus, in accordance with the following data given by the model and the corresponding analysis, at the same time, because too many variables affect the number of comprehensive analysis of its request for them to carry out principal component analysis )

当信噪比低，小信号输入时噪音严重，在整个音域的声音明显变得浑浊不清，不知发的是什么音，严重影响音质。信噪比的大小是用有用信号功率（或电压）和噪声功率（或电压）比值的对数来表示的。(When the signal to noise ratio is low, serious small signal input noise, the sound of the entire range becomes significantly turbid, I do not know what made the sound, seriously affecting the sound quality. Size is the number of the signal to noise ratio by the ratio of desired signal power (or voltage) and the noise power (or voltage) represented.)

HHT是历史上首次对Fourier变换的基本信号和频率定义作的创造性的改进。他们不再认为组成信号的基本信号是正弦信号,而是一种称为固有模态函数的信号(HHT is the first time in the history of the Fourier transform basic definition signals and frequencies for creative change Progressive. They will no longer signal that the basic component signal is sinusoidal signal, but as an intrinsic mode function signals)
