Combining the definition of CWT and the derivative property of convolution, we constructed a general method to calculate the approximate derivative of signal through CWT by using the first and second derivative of Gaussian function, Haar, and the first derivative of three-order-Spline function as wavelets. As compared with the other approaches of calculating derivative, which include the numerical differentiation, polynomial filters, Fourier transform, and the recently proposed DWT method, fast calculation and simple mathematical operation were remarkable advantages of CWT method. For the signal corrupted by severe noise (Signal-toNoise Ratio=5), the satisfactory results could also obtained via CWT method through appropriately adiusting the dilations.

Subsequently, the concrete forms of measure calculation equations of self-similar fractal obtaining by based on the definition of form in fractional-dimension calculus about general fractal measure are discussed again, and the differences with Hausdorff measure method or the covering method at present are given. By applying the measure calculation equations, the measure of self-similar fractals which include middle-third Cantor set, Koch curve, Sierpinski gasket and orthogonal cross star are calculated and analyzed.

They were both easily to be dissolved in dilute alkali. When the pH gradually increases, the ring-opening speed of the derivative is higher than that of GB. The derivative was obviously affected by solvent and higher temperatures. When GB was dissolved in PEG, the peak of the derivative disappeared at 50 ℃ for 15 h or at 120 ℃ for 4 h. Besides the main peak of GB, there appeared a small peak with a retention time of 1.2-3.0 min after heating 4 h at 120 ℃. The result showed that the derivative was in a high energy state, and GB had a better stabilization.

溶剂和温度的综合作用对衍生物的稳定性影响更加显著，GB在聚乙二醇溶液中分别于50 ℃下保存15 h和120 ℃下保存4 h后其中的衍生物峰全部消失；将该溶液于120 ℃下保存4 h后分析，除有主峰GB外，在保留时间为1.2～3.0 min范围还伴随有小峰出现，这说明衍生物处于高能态，GB相对较为稳定，两者共存，且相互转化；在特定条件下衍生物能全部转化为GB。

测井曲线的值是深度的函数，测井曲线的一阶导数表示了曲线变化的趋势和变化的快慢，在某一范围内，当一阶导数呈现符号转换时，相对应的深度点的测井值即为该范围内极大值；测井曲线的二阶导数则表示曲线的凹凸性，在某一范围内，当二阶导数呈现符号转换时，相对应的深度点代表了测井曲线的拐点，即反映曲线凹凸性变化的转折点，亦即地层的分界面。

The 10 a plot had the highest community average height, abundance, and above ground biomass, but the community average increased with enclosure time and the 25 a plot had the highest community average coverage. Enclosure for 10 a gave the highest species diversity index in the third plots, while 15 a had the highest' richness index and lowest evenness index. The highest evenness index was in the non-enclosure plot. Exclosure appears to maintain or conserve, rather than increase plant diversity in contrast to non-enclosure.
