該演算法把混沌變量加載于免疫演算法的變量群體中，利用混沌搜索的特點對群體進行微小擾動並逐步調整擾動幅度，明顯改善了免疫演算法的群體多樣性。First, this paper gives an introduction of some methods of unequal probability sampling, their estimators and variance estimators, including sampling with pps with replacement, methods of sampling without replacement suggested by brewer, durbin, sampford, des raj, murthy, rao - hartley - cochran. then, at the basis of rao and bayless ' s study, we consider that population can be splited two random subpopulations, which are respectively drawn from different infinite super - populations, and compare the stabilities of estimators of the methods that given above. we find that the minor difference between two super - populations has great effect on the efficiency of the estimators for the population with moderately large coefficient of variation ( c. v. )
本文首先從理論上介紹了若干種不等概率抽樣方法，它們的估計量、估計量的方差及其估計，其中包括有放回ppz及pps抽樣，不放回不等概率抽樣中的brewer 、 durbin 、 sampford 、 desraj ， murthy 、 rao - hartley - cochran等人的方法；其次，在rao和bayless兩人就樣本單元數n = 2的情形對上述抽樣方法進行比較的基礎上，將總體隨機地分成兩個子總體，視每個子總體取自不同的線性超總體，在文中，我們利用計算機實現隨機分組，並通過畫圖比較各方法估計量的穩定性，結果表明，對變異系數c . v . （ x ）較大的總體而言，兩個超總體之間的微小差異將對估計量的穩定性產生很大的影響，從而說明rao和bayless的比較結果還不夠完善。The results show this approach is effective when there is massive cloud cover on the remote sense image. wavelet analysis is internationally recognized up to the minute tools for analyzing time - frequency. it is chiefly due to the " adaptive feature " and " mathematical micro - telescope feature "
小波分析是目前國際上公認的最新時間-頻率分析工具，由於其「自適應性」和「數學顯微鏡性質」而成為許多學科共同關注的焦點，本文利用小波改善傳統數字圖像處理方法，取得了一定效果。According to the analyses of the research results about the feasibility of 4 - d seismic and the successful 4 - d seismic cases of foreign companies, the author put forward the suggestions for 4 - d seismic pilot area selection ; briefly analyzed the influential function of producing way on the seismic response ; utilized theory calculation, coring data analyses, and reservoir numerical simulation to define the fluid substitution effects on the p - wave velocity. through long time water driven to the reservoir, some of the properties and the log curves have changed, the author tried to find the variation rule of the reservoir and its effects on seismic velocity. the " blind point " in 4 - d seismic feasibility study both in china and overseas was found, that is the lack of consideration of the influence of physical property variation by long time water driven on the seismic response
在深入分析國外四維地震可行性研究成果和成功實例的基礎上，提出了有利於水驅四維地震成功的工區優選條件；簡要剖析了各種開采方式及其對地震特性的影響；利用理論計算、巖心分析、油藏數值模擬三種方法確定了流體替代對縱波速度的影響；通過對長期水驅造成的物性參數、測井曲線以及油藏溫度和壓力變化規律的總結，分析了這些變化對地震速度的影響，指出了目前國內外水驅四維地震可行性研究中存在的盲區?沒有充分考慮長期注水造成的物性、溫度和壓力變化對地震響應的影響，完善了水驅四維地震可行性研究的內容；在考慮了這些變化因素后，高29斷塊水驅四維地震可行性研究結果表明：四維地震監測注水前沿可能要比監測油藏變化容易的多；以四維地震巖石物理可行性研究結果為基礎，提出了五個有助於突出四維地震造成的微小差異的途徑，為今後水驅四維地震研究指明了方向。Nowadays, business in financial fields becomes more and more competitive, in addition to an unoptimistic outcome appeared in financial leasing industry in recent years, which requires companies involved should be at a higher standard indeed
它具有帶動產業結構升級、拉動國內需求、盤活資產存量的宏觀經濟功能和支持中小企業發展、提高資金利用率、改善企業經營管理、資產負債結構等微觀經濟功能。It was found that the introduction of ca2 + enhanced the sinterability of the material. the relative density of sintered specimens increase with the content of ca2 + in the composition range of 0 < x < 0. 3. it was confirmed that a high relative density can be obtained at relatively low sintering temperatures by using uniform, high surface area la1 - xcaxcro3 powders, which modifies the crystalline structure and microstructure of ceramic specimens
研究結果表明， a位ca ~ （ 2 + ）的引入在一定程度上能夠降低材料的燒結緻密化溫度：細小、均勻、高比表面積的粉料能夠有效降低材料的燒結緻密化溫度；燒結溫度的降低可以減少la _ （ 1 - x ） ca _ xcro _ 3中液相含量和鉻氧化物的揮發，有利於材料晶體結構、顯微結構的改善。And the process of creating learning enterprises should follow : " starting from the tiny change ", " focusing on developing factors and paying more attention to restrictive factors " and " driving the learning circulation ". finally, the practicing ways of creating learning enterprises may be appraised by the criterions of individual achievements, strengthening the relationships among the people who want to create the learning enterprises and improving the organization ' s performance
這個過程應該遵循從微小變化開始、利用成長因素更要關注限制因素以及推動深層學習循環的基本思路進行，並且可以從個人成果、實踐者聯系的增強以及經營成果的改善三個方面來評價創建行為。分享友人
