Then, the fronts .of different intensities are superposed on the orographic disturbances and pushed by basic geostrophic flow to climb over the orography.

通过非静力模式讨论了两维地形扰动与锋面的相互作用，研究了不同基本气流，包括正压、斜压、层结强弱差异，不同尺度的地形，包括不同高度和不同宽度，强弱不同的锋面等多种情况下地形扰动与锋面扰动的相互影响，发现地形尺度和气流的性质不同带来的结果是有差异的，中尺度地形使冷锋在迎风坡锋消，在背风坡则是锋生和锋消相间的波状分布，表现为锋面在山顶附近锋生、快速下坡过程中锋消和山脚处锋生的分布特征，这与半地转模式中地形的动力作用使冷锋在背风侧单纯加强是不同的。

A new distribution is proposed for the sake of the disadvantage of the constant circulation at present. The axial velocity in fornt of the blade intake along the radius reduces linearly, and the velocity trendline behind the blade export is close to parabolic curve, but the circulation should be decided by designers.

By selecting the urban population data of five years after Chinese reform and opening, use double logarithmic model on the research of the Zipf's law between the cities'size and urban hierarchy. By getting the data of Chinese cities'distribution, analyze the development trends of Chinese cities'distribution Zipf's index with the parametric test, nonparametric test and analysis of variance.

本文通过选取改革开放后5年的中国城市人口数据，运用双对数模型对我国城市规模和城市等级之间的Zipf法则关系进行实证研究，在得到我国各个省份城市规模分布值的基础上综合使用参数检验，非参数检验和方差分析等方法对我国城市规模分布Zipf指数的发展趋势做出分析。

To acquire the inherent topology properties and characteristics of the topology graph at AS-level, we introduce basic network model (Scale-free network and Small-world network) and evaluating parameters (such as cluster coefficient, average path length, degree distribution, Pearson correlation coefficient) in this thesis. Through thorough analysis of the topology of the generating topology at AS-level, we can see some apparent properties with the evaluating parameters and the inherent power-law distribution property of the derived topology. Besides, we discuss the perspective of the evolution of the networks topology based on these analyses.

为了研究Internet自治系统级拓扑的内在拓扑特性和规律，利用了复杂网络的基本网络模型(无标度网络和小世界网络)和度量参数(簇系数、平均路径长度、节点度分布、皮尔森系数等)，对生成的自治系统级拓扑进行了大量的分析，从中可以看出度量参数具有一些明显的特性，拓扑中具有一些幂律分布特性，并对网络拓扑的演化发展的趋势进行了探讨。

The more important is that it influenced the direction and the method of some generations. Many scholars devoted themselves to the study of meteorology, pedology, the geographical distribution of population and nationalities, etc..

更为重要的是，它影响了几代中国地理学者的研究方向和研究方法，使许多学者致力于气象学、土壤地理学、人口地理分布和民族地理分布等的研究工作。

物种形式：指自由离子、离子对和络合物等水溶组分的平衡分布（是相分布、质量转化和反应途径计算的整合部分。

Finally, PNV had been mapped according to Boolean discrete methods to connect climate submodel and vegetation submodel by GIS. PNV map first represented the spatial distribution of all vegetation types of 4 physiognomic levels in Taiwan, also integrated the diverse comments of altitudinal vegetation zones and geographical climatic regions in the past. Besides, the scattered ranges of 36 dominant trees in the moisture-thermal regime and climatic zone had been drawn via coordinating 585 plot-data with MWI and WDI.

为达绘制潜在植群图之最终目标，本研究以MWI及WDI之网格图层代表气候亚模型，以潜在植群形相分类方案之各阶类型代表植群亚模型，藉由布林分离法联系此2亚模型之关系，建构气候–植群分类模型，并以地理资讯系统绘制出包含群系纲、群系亚纲、群系组、群系之潜在植群图，首次完整呈现台湾各阶植群类型之空间分布，合理说明了山地植群带分化、北部植群下降及西南部冬季乾旱等现象，亦整合过去各种有关垂直性山地植群带状分化与水平性地理气候区划分的复杂意见；另外，本研究将585个样区林木座标标定於MWI及WDI，绘制36种林木於水热境制及热量气候带之分布范围。
