Thinking about that , we must establish one system - " stereoscopic manage - counter system " by goverment , university and society to tacle of market " hand - out - sight " and goverment ' s management " hand - in - sight " and the system of university itself . it eliminate to the room of unit system of university . deely implement the concract system of 因此，要建立政府、高校、社会多方位多元素配套体系?一“立体式管理一反馈机制” ，发挥市场这只“看不见的手”和政府管理这只“看得见的手”的功能，完善高校自身约束机制，杜绝高教单位制生存空间，从而把高教契约制真正落到实处。
Using regional geochemical exploration data , the authors figured out moving window contrast values through window moving average operation , delineated single element anomalies and multi - element accumulative ( multiplicative ) anomalies according to contrast values , and drew single - element and multi - element background diagrams , accumulative ( multiplicative ) multi - element contrast anomalies and background diagrams , which make up the locating prognostic chart for the ore - prospecting target 摘要利用区域地球化学勘查数据，经过窗口滑动平均，计算出滑动窗口的衬值，通过衬值圈定单元素和多元素累加（累乘）异常；在窗口滑动平均值基础上勾绘单元素和多元素背景曲线图、累加（累乘）多元素衬值异常和背景曲线图，制作找矿靶区定位预测图。
So the study and use of compound powders and thin films get more and more regards . among them the double layered structure nanocompound semiconductor become the focus of study by their high photocatalytic efficiency , fast reaction speed etc . it has been confirmed that the potassium niobate ( k4nb6o17 ) is an excellent semiconductor photocatalyst . its special construction consists in the ion k + in the interlayer can be replaced by other cations , which providing vast space of modifying the material 层状化合物中的铌酸钾k _ 4nb _ 6o _ ( 17 )已被证实是一种性能优异的半导体材料，具有光催化和光电转换性能，其独特的结构是处于层间的带正电的k ~ +可以被其它阳离子所替代，正是由于其多元素、复合型的特点，为材料的修饰和改性提供了广阔的技术空间。
In order to overcome problems arisen from the application of x fluorescence analysis into complex spectrum produced by archaeological ceramic fragments with multi - element , low content and thick ground , we have employed the artificial neural network into the research of x fluorescence archaeology and conducted three kinds of research works . as the first one , we have applied the linear olam network ( optimal linear association memory network ) and the non - linear bp network ( back - propagation network ) respectively to analyze the complex x fluorescence spectrum of archaeological samples , and taken both results of spectrum analysis to compare with each other . the second , the method of pattern recognition of bp network was tentatively used to perform intelligent identification of production places of these archaeological samples 针对科技考古中对大量考古陶片进行产地研究时x荧光分析对多元素、低含量、厚基底考古陶片产生的复杂谱分析的问题，将人工神经网络引入x荧光考古中，进行了三方面的研究工作：一是用线性olam网络(最优线性联想网络)和非线性bp网络(误差反传导网络)分别对考古样品的x荧光复杂谱进行解谱，并比较二者的解谱效果；二是用bp网络模式识别方法对考古样品的产地进行智能识别；三是为了提高网络运算的可靠性和减小基体效应及电噪声的干扰和影响，研究并提出了三种网络学习前的谱数据预处理方法。
