And the average WDI for every month was calculated from 60 decades WDI and the drought frequency for every month was obtained with a drought criterion. Results showed that: in spring, North-western China, Northern China and Southern China have a higher drought frequency; in May to August, the region that has a higher drought frequency focus on North-western China and Northern China; from September to December, North-western China, Northern China, center China and Sichuan basin has a higher drought frequency (6) The relationship between average WDI for all the 720 decades in 20 years and average precipitation was analysed and was used to regionalize drought in China.

5分析我国近20年干旱发生的时空分布特征：利用1982-2001年NOAAAVHRR8km数据集，计算了20年来我国各旬干旱空间分布，并根据一定的干旱发生判断标准，统计我国不同地区在各月相发生干旱的频率和各月份平均WDI，初步分析我国干旱发生的时空格局，结果表明：在春季，西北地区、华北平原和华南大部分地区的干旱发生频率都比较高；在5-8月份，高频率干旱发生地区就主要集中在西北和华北平原地区；9-12月份干旱发生高频率地区在主要在西北、华北、华中和四川盆地等地。

透过台湾都会区相邻国民中小学校园规划配置图，归纳分析出相邻国民中小学校园规划型态及教育空间资源共享强度，分析结果显示教育空间资源共享强度依强至弱依序为集中型、合院型、散落型。

A transportation engineering research and development program assessment method basing on DEA is formulated for prediction of efficiency index, production possibility set's restraint coefficient and inputoutput slack variable. Then use the reciprocal process of principle factor method to calculate the effective availability of research and development personnel and funds.

并采用构建基于投入的交通科技项目C^2R模型，分析投入因子的效率评价指数、生产可能集约束系数和投入／产出松弛变量，结合因子分析逆向求解得到投入指标的有效值，从而得出交通科技项目投入人员及经费的有效利用率。

With the application of SPA degrees of connection in analysis and comparison of the spike scoring of Zhejiang team and Shanghai team in the men volleyball final match of "Bubugao Cup" in 2002～2003、2003～2004 season,the author points out the problems of Zhejiang team.The power dink is weak,the back row attack is faltering and the 3-position power attack is weakened.

通过把集对分析中的联系度引入到2002~2003、2003~2004赛季"步步高"男排总决赛中浙江男排和上海男排的扣球得分情况的分析与比较，指出浙江男排强攻不强、后排进攻疲软、传统强攻3号位进攻点减弱的现实问题，同时也发现上海男排通过强有力的进攻和有效的拦网较好地遏止了浙江男排的进攻势头。

Using ANSYS to make FEM analysis for the orbiting model and got the integration displacement transfiguration and equivalent stress transfiguration diagram and verified the validity and practicability of general scroll profiles integration design theory.

利用有限元分析软件ANSYS对通用涡旋型线集成型线压缩机的动涡盘进行了有限元分析，得出了在运动状态及气体力作用下的综合位移变形图及等效应力变形图，验证了通用涡旋型线集成设计理论的正确性。

Neutral differential equations with variable sign coefficients are separated into neutral differential equations with positive and negative coefficients by transformation. According to the characteristic of these equations, a real number set with supremum is constructed, and sufficient conditions for oscillation of all solutions to neutral equations with variable sign coefficients are obtained.

At present, termination analysis is based on triggering and activation graphs, the result of which is conservative.

目前有关主动规则集终止性分析的主要依据是触发图和活化图，其分析结果是保守的。

On the base of large quantitative test, using coal petrography and organic geochemical data, the source of oil and gas in the coal-measures is analyzed. And it is concluded that the area's Yan'an group coal-bed has a low potential of oil production, and the oil and gas contained in the coal-measures and superjacent strata comes from underlying Upper Triassic Yanchang group strata. After a series of parameters of coal seam and surrounding rocks are tested, gas formation, storage, preservation, permeability of the coal-rock seam are analyzed and evaluated.

本文在大量测试工作基础上，利用煤岩学与有机地球化学资料，分析了煤系油气的来源，认为本区延安组煤系煤层生油潜力差，煤系及其上覆地层所含油气为下伏上三叠统延长组源岩所生，油气主要通过迭置的砂体、不整合面、构造裂缝等自下向上运移进入煤系；通过对煤层及围岩一系列物性参数的测试，分析与评价了煤岩层的生、储、盖、渗性能与可抽放性，得出主采4_(-2)号煤层属中等储集、低渗透层，围岩封闭性差，渗透性高，煤层瓦斯含量低，而顶板砂岩瓦斯含量高，为采面瓦斯涌出的主要来源。
