实际的证明

To further understand and correctly master the notion of marginal spectrum in Hibert-huang transform, the linear property of marginal spectrum is demonstrated, an mistake to the notion of marginal spectrum in some documents is pointed out, and a new viewpoint about the essential difference between marginal spectrum and Fourier frequency spectrum is put forward by which the amplitude of Fourier frequency spectrum only represents the probability that a frequency objectively exists in a signal while the amplitude of marginal spectrum decides whether a frequency objectively exists in a signal.

为了深入理解和正确掌握希尔伯特－黄变换（Hilbert-Huang Transform，简称HHT）中的边际讲概念，证明了边际谱的线性性质，指出了文献中对边际谱概念的一种误解，提出了边际普与Fourier频谱之间本质区别的一种的新观点，即Fourier频谱的幅值只能反映频率在信号中实际存在的可能性大小，而边际谱的幅值则能真实反映频率在信号中是否存在。

After certifying the irreality of ideal filtering function, we can get a better filter selecting a proper window function. Comparing two actual filters, we designate a good"Panama hat"filtering function. Meanwhile, an effectively linear interpolating function is introduced to raise the image reconstruction quality. Describing its realizing steps on the micro-computer briefly, we reconstructed some images from the anlogue projections of some models. The number of projection views is 180, 100 same interval parallel lines per view; the size of reconstructed images is 64×64 pixels with 64 gray levels; the reconstructing speeds are 40" on PC-386 and 12"on PC-486, respectively; each pixel is 0.31mm.

在证明了理想滤波器的不可实现性之后，得知通过选择适当的窗函数可获得很好的滤波函数，经过两个实际滤波器的效果对比，我们选取了较好的"巴拿马帽"形滤波函数，同时也介绍了一个有效的提高重建质量的线性内插函数，概要地叙述了平行射束图象重建的计算机具体实现步骤后，对几个物体的模拟投影数据进行了重建：投影角为180°，每视角下有100个平行投影数据点，在386微机上重建尺寸为64×64，时间约为40秒；在486/33MHz微机上只用了12秒，图象的象点精度是0.31mm。

The requirements of efficiency and global-optimization can be met at the same time. Based on the situation of time varying of parameters of system, before entering the inference machine, the fuzzy control rules is learned and tested online by a special designed "judger", the excellent performances of fuzzy control rules which use online control is ensured. Fuzzy cerebellum model articulation control CMAC is used to control the semi-active suspension system for the first time. The convergence of this control algorithm and the convergent range is presented.

并根据实际系统参数时变的特点，用"判别器"对即将进入推理机的模糊规则进行了在线学习和测试，保证了用于实时控制的模糊规则的优良；首次应用模糊小脑模型神经网络控制器对系统实施了控制，并证明了这种控制算法的收敛性，得出了收敛范围；仿真和试验结果表明，GASAF和 FCMAC这两种智能控制算法对车辆的平顺性都有较大的改善，实时性较强。

Finally the method given in this paper is used in the design of a real foundation pit case to test its applicability. The result proves that this method conforms to construction reality. It can save the cost of retaining structure, and is very efficient.

His thought of separating political power, compared to the previous thinkers, is not an impractical political preaching but a political agenda with great practical significance.

他的分权制衡思想与以往的思想家相比，并非是空洞的政治说教，而是具有实际意义的政治纲领，在许多国家的政治实践中得到充分证明是有效的。

" These anthropomorphisms are used merely to suggest the personal life and activity of God, and are not literal personifications, as is conclusively proved by the fact that phrases which would be actual anthropomorphisms-eg,"God sees with His eyes";"He hears with His ears";"one sees God's face"("head,""body, etc.)-never occur.

这些anthropomorphisms使用只是为了表明个人生活和活动的上帝，而不是字面personifications ，这是确凿的事实证明了这一词组将实际anthropomorphisms ，例如，&上帝将与他的眼睛&，&他听到了他的耳朵&，&人们看到上帝的脸&（&头&，&身体&，等等），永远不会发生。

Thus Professor Tyndall, in his famous Belfast address, proposed this view, maintaining that modern science has proved the physical value of prayer to be unbelievable.
