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。

This research was conducted in degraded rangeland at the southwestern edge of the Mu Us sandland, Yanchi county, Ningxia, the soil seedbank features and its relation to vegetation was analyzed using similarity analysis and ordination method, the results show that seeds within soil distribute mainly in 0~5 cm soil layer, less seeds in 6~15 cm soil layer in exclosed and non-exclosed rangeland, for seeds in exclosed soil, species richness and diversity index H are higher, while D is lower, exclosure measure, generally speaking, can increase plant species and amount of vegetation and seeds in soil, some annual plants, mesophytes and halophytes appears in the soil or surface.
以毛乌素沙地西南缘宁夏盐池县的退化草场为研究对象,采用相似性分析和排序方法对封育和未封育草场土壤种子库的特征及其与地上植被间关系进行了研究,结果表明无论封育区还是未封育区,土壤种子库中的种子主要分布于0~5cm的土层,6~15cm土层的种子数很少;封育区土壤种子库的物种丰富度大于未封育区,物种多样性则表现为H 值较大,而D值较小,总体上看封育措施可以提高地上植被和土壤中种子的种类和数量,一些一年生植物、中生植物和盐生植物开始出现在地面或土壤种子库中。

Naturally,we confront with such a problem:can we generalizethe systematic work on the classical boundary value problem for analytic func-tions and singular integral equation to Clifford analysis?And so this problemhas especially theoretical and practical meaning,and naturally this problem hasbecome a common hot topic for mathematicians at home or abroad.
其结果在一定程度上推广了一些经典文献的结果,取消了这些在经典文献结果中对s=0或s=n的条件限制,需要指出的是,据作者所知,到目前为止,本文也是第一次系统而又比较深入地研究了取值在泛Clifford代数〓上的超复函数的性质,并获得了比较系统而又深入的结果;另外,本文还对Clifford分析中的某些比较特殊的Riemann边值问题与奇异积分方程做了一定程度的研究,由于文中所用的方法较曾经出现的文献而言有着根本的改进,因此,本文去掉了从前在这一问题的研究过程中所做出的一些不必要的条件限制,从而使得在比以往条件更弱的情况下,获得了比以前文献中更多的结果。

The inward current in OHCs was totally inhibited after the superfusion of 100μmolIL and 200μmo1/L linopirdine respectively. The outward rectifier K(superscript +) current I(subscript K was the dominant K(superscript +) current in the whole cell currents in Deiters' cells. In the presence of 200μmol/L linopirdine, the current was not significantly affected.

With the observation of the outward appearances, it can be known roughly that if the sample was added with adulterations. Since the beeswax dissolves in the benzene but the adulterations, such as gypsum, starch and so on do not, these can be determined. By the verification of acid value and alcohol dissolve ability, the acid or non acid added can be determined. By the change of saponification value, the ester or non ester added can be determined. By the carbonification degree in the concentrated sulphuric acid, the mineral wax, such as paraffin wax added can be determined.

The outward rectifier K+ current current was the dominant K+ current in the whole cell currents in Deiters' cells. In the presence of 200μ M linopirdine, the Ik current was not significantly effected. Our findings demonstrated that the KCNQ heteromeric or homomeric potassium channel may be the molecular basis for the peak outward K+ current and testified that the inward IKn current is mediated by KCNQ potassium channel.
