The EOF loadings corresponding to the five highest eigenvalues were used to delineate the air quality regions. The results of EOF method were difficult to interpret because they tend to cluster most stations into the first group. The results obtained by rotated EOF and cluster analysis are similar and more reasonable. It is interesting to note that the clustering results based on 1h and 8h data are similar. The principal component time series of EOF and REOF were analyzed to determine their temporal characteristics.

EOF和REOF法中均采用特徵值为最大的五个EOF负荷作为分区的依据，以EOF划分均质区后容易将大部份测站划为同一区而造成解释困难，而采用REOF方法和群集分析法所得结果相似且较为合理，利用最大小时与八小时臭氧浓度进行划分结果接近，本研究也针对EOF和REOF所求出的主成分时间序列加以分析，以了解其特性。

The scrap metal are steel, ferreous and non ferreous. the grade of the steel I dont have the exact classification. If I have to class them, then we would have more time consuming and it will cost more money to seperate them.

钢的、含铁或不含铁的废金属，我们没有精确的划分等级标准，如果我们去划分它们，我们将花费大量的时间，并且会浪费很多钱来区分他们。

Recent results indicate that （1） Oryzeae is monophyletic and falls into two main clades corresponding to the traditionally recognized subtribes;（2） Close affinities of the monoecious genera are not supported, suggesting the multiple origins of unisexual florets;（3） Previous recognition of three monotypic genera （Hydrochloa, Porteresia and Prosphytochloa） is not justified;（4） Based on dating using molecular clock approach, it is estimated that Oryza and Leersia branched off from the remaining genera of Oryzeae -20 million years ago, and separated from each other -14 MYA.

目前已有的研究结果表明：稻族是单系类群，可分为两个主要分支，相当于传统的两个亚族（Zizaniinae和Oryzinae），但稻族单性花小穗是多次起源的，不宜作为划分亚族的依据；一些单型属（Hydrochloa、Porteresia和Prosphytochloa）的建立得不到分子证据的支持；根据分子钟原理估计稻族两个主要分支的分歧时间在大约2000万年前，而稻属和近缘属假稻属Leersia的分歧时间为1400万年：稻属内主要类群的分歧时间在900万年前左右。

It abandon the traditional measure that divide the development course of the scientific and technological park according to the time, and redistrict their development courses according to the logic route that the park grew up, then divide development course into three stages: embryonic stage, it introduce domestic and international agricultural new and high technology , advanced equipment directly, engaged in running an enterprise on a commercial way, use the new and high technology to carry on precise, deep processing or storing and keeping fresh to the high-quality agricultural and animal products, do not have cooperation with local peasant basically; the stage of growing up, the park brings along local peasants production, does not confine to the production of the industrial base in the park again, a kind of nonstandard cooperative form has appeared between peasant and park; at ripe stage, the park sets up the training center of agricultural science and technology, carry on the professional technical training to the industrial base and peripheral peasant, spread through three kinds of diffusion effects, such as radiation, the grade

摒弃了按时间划分科技园区发展历程的传统作法，按照园区成长的逻辑路线对其发展历程进行了重新划分，将发展历程分为三个阶段：萌芽阶段，园区内直接引进国内外农业高新技术、先进设备，从事企业化生产，运用高新技术对优质农畜产品进行精、深加工或储藏保鲜，与当地农户基本上没有合作关系；成长阶段，园区带动当地农产生产，不再局限于园区內产业基地的生产，农产与园区之间出现了一种不规范的合作形式；成熟阶段，园区建立农业科技培训中心，对产业基地及周边农产进行专业技术培训，通过辐射扩散、等级扩散、跳跃扩散三种扩散效应，把经济动力和创新成果传导给周围地区，园区进入规范化管理阶段。

3D model produce enormous degree of freedom.(3) Simulating have to employ multi-step load for moving heat source. In order to solve problems mentioned above and improve solution accuracy, this paper choused suitable material property parameter, and used transition mesh, with two point and line heat sources model. The program which applyload of moving heat sources and suitable time step was edited by means of ANSYS' APDL (ANSYS Parametric Design Language).

为了解决这一问题并提高计算精度，本文对高温时材料的物理性能参数进行了适当的选取和处理；采用过渡网格划分形式划分网格以保证焊缝处网格足够细小；点热源选取高斯函数分布和线热源进行叠加，利用ANSYS软件的APDL（ANSYS Parametric Design Language）语言编写程序实现移动热源的加载；选取适当的计算时间步长。

And, it establishes the computer model with the Scott·Henseleit method, which analyses and optimizes the ventilation network and auto-creates the figures of the evading disaster and succoring disaster with the computer. The paper establishes the GM(1,1) gray forecast model, and forecasts the amount of gasemission of the laneway based on the history data, and then compartmentalizes the danger grade for the laneway. Utilizing the principle and method of cybernetics, the paper brings the feed-forward and feedback. controlling method on the hidden risk in the mine, namely, the double-loop model of forecasting and early- warning. Especially in the feed-forward forecasting, the paper adopts the one unit non-linear regression analysis and forecast method, and forecasts the hidden risk amount in the mine during some time, and compartmentalizes the hidden risk grade based on the history data.

Then based on CWMS, we propose a new method to enhance the resolution of seismic traces. Firstly, we divide the seismic signal into proper segments by Gabor molecule-windows adaptive to the signal, where each segment is regarded stationary, and then transform it into the Gabor domain. Secondly, we deal with the amplitude spectrum for each segment to expand the frequency band of the spectrum in the Gabor domain. Finally, taking inverse Gabor transform on modified time-frequency coefficients, we get the high-resolution signal.

然后基于变子波模型，提出了一种新的提高地震记录分辨率的方法：第一步，用自适应于地震记录的Gabor分子窗把地震记录恰当地划分成若干片断，每段内信号近似平稳，然后将地震记录变换到时间-频率域；第二步，在变换域对每个分子窗内信号的振幅谱进行处理以拓宽频带；最后把处理后的时间-频率域函数反变换回时间域得到提高分辨率后的结果。
