variation

Therefore , if the soil water properties and soil water - storage was studied with traditional statistic method , we would not know the variate are dependent or independent , whether the results have spatial distributing pattern or not , even not know whether the number of sample is economical and rational or not 因此用傳統方法分析土壤水分特性和水庫貯量并不清楚所得的數據是否相互獨立,是否存在一定的空間分布格局,更不知道所確定的取樣數量是否經濟、合理。地統計學是研究土壤特性空間變異和空間分布格局最有效的方法之一。

By applying the theory and method of geological anomaly , it is focused on the analysis of the characters of major geological anomalies and their effect of mineralization in daye - jiurui region . the analysis result shows that the basement fault anomalies control a few major large hidden batholiths and their associated orefields ; that the anomalies of cover structure confine most cu - au deposits and fe - cu deposits within their scope ; that the geochemical anomalies and lithofacies - paleogeographical anomalies are major geological factors leading to trataboundness of some cu - au deposits ; that the anomalies of rock operties provide the favorable chemical and physical conditions for the ore - forming process , including the seepage , circulation , convergence and deposit of ore - bearing hydrothermal solution ; that the anomalous ctive stage of mesozoic magmatite is almost consistent with the major mineralization epoch of the fe , cu deposits , and the structure of multi - levels , and the zoning in magmatic system determine the spatial distribution of the mineralization system . then , based on the above analysis , a comprehensive variate , geological combination entropy , is brought forward for reflecting the complex degree of the combination of geological ore - controlling factors . after circumscribing the anomalies of geological combination entropy , the relations between the anomalies and ore deposits are determined 從地質異常的角度,重點分析了大冶九瑞地區主要地質異常的特征及其對成礦的影響.由分析可知:基底斷裂異常控制了本區若干重要規模較大的隱伏巖基及伴生礦田,而蓋層構造異常控制銅金礦床和鐵銅礦床的空間位置;地層的地球化學異常和巖相古地理異常是造成一些銅金礦床層控性的主要地質因素;蓋層的巖性異常為含礦熱液的滲流、循環、聚集和礦質沉淀等一系列成礦作用提供了有利的物理和化學條件;中生代巖漿巖的異常活動期也是本區主要的鐵銅成礦期,巖漿巖系統的多層分枝和分帶性結構控制了本區成礦系統的三維空間分布.在上述分析的基礎上,構置了地質組合熵作為反映控礦地質因素組合系統結構復雜程度的綜合變量,并圈定出組合熵異常,由此確定了綜合地質異常與礦床的關系

Nonparametric model is widely used in the practical problems , the reason is that the form of the regression function in the nonparametric model is free , and the limits to the random variate ( x , y ) are fewer . in the past several decades , this model is studied carefully by the researchers of statistics , and many achievements are arrived in both theorial fields and in applicational fields 非參數回歸模型,由于其回歸函數的形式可以任意,而且對隨機變量( x , y )的分布限制較少,因而在實際中有著廣泛的應用背景。幾十年來,統計工作者對這一模型進行了深入細致的研究。無論在理論上還是應用上,都取得了許多優秀成果。

Based on the theory of stochastic finite element , the structural parameters of frame - shear structure including stiffness and mass and damping are simulated to be stochastic variables . by solving recurrence equation of stochastic finite element , the duration curve of mean value and standard deviation of seismic response can be obtained for every floor of frame - shear structure . an analysis is thus given to the effects of independent variation and simultaneous variation of structural parameters on the seismic dynamic response of frame - shear structure . as shown by the results , with regard to frame - shear structure , the effect of variation of strucural parameters on the change of mean value are chiefly the increase of standard deviation of response . variation of stiffness will cause the response of frame - shear structure to variate greatly ; variation of mass shows less effect ; and variation of damping shows insignificant effect . the effects of simultaneous variation of various structral parametres on seismic response are only slightly greater than the effect of stiffness variation alone 以隨機有限元理論為基礎,將框剪結構的剛度、質量、阻尼等結構參數為隨機變量.通過求解隨機有限元的遞推方程,得到框剪結構各層的地震動力響應均值和標準差歷時曲線.分析結構參數單獨變異,以及同時變異對框剪結構地震響應的影響.研究結果表明,對框剪結構而言,結構參數的變異對響應的均值變化影響都不大,主要是增大響應的標準差.剛度的變異性將引起框剪結構的響應發生大幅度變異,質量的變異性影響稍小,阻尼的變異性影響不顯著.結構各參數的同時變異,對框剪結構地震響應的影響,僅比剛度單獨變異的影響稍大
