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。

We established the statistical models for this site with the flux components, NDVI and other impact factors (precipitation, photosynthetically active radiation), and we validated the model at the site. The results of validation indicate that the model we established can well simulate the characteristics of flux components.

3利用生长季期间的NDVI时间序列数值，在1：100万中国草地资源数据的基础上进行聚类运算，在典型高寒草甸区域上划分出与海北通量观测塔所在处具有相似NDVI时间动态变化的区域，将此区域作为我们的通量扩展区域。

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.

论文中，利用斯考特·亨斯雷法建立计算机模型，对矿井通风系统进行解算和优化调节，并通过计算机自动生成避灾、救灾路线图；建立灰色GM(1，1)预测模型，对巷道瓦斯涌出量进行预测，进而对巷道中的瓦斯事故危险性进行危险等级划分；利用控制论的原理和方法，提出了煤矿通防隐患前馈——反馈控制方法，即预测、预警双环模型，采用一元非线性回归分析预测方法，对煤矿某一段时间内的隐患数量进行预测，并结合历史数据，对当前煤矿隐患排查处理状况划分等级，分别予以管理和控制。

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。

The basic concept of FOP can be summarized as to further optimize effective prescription according to the standard of curative effects and with the aid of modern science and technology and theories of traditional Chinese medicine.
