The studying method of flora adopted by this thesis are follows : the statistics of the dominant families and genera , along with single families and genera , abundance index ( ai ) , similarity coefficient of genus ( scg ) , floristic spectrum analysis ( fsa ) , principal components analysis ( pca ) , as well as agglomerative classification analysis ( aca ) 16 ;單種屬占總屬數的39 39 ,其種數僅占總種數的門26 ;而6個優勢科中所含的種數占到總種數的903 , 9個優勢屬中所含的種數占總種數的47

In this article the chelating precipitation method and the converting precipitation method were chosed to synthesis zno nanoparticles on the basis of the theory of synthesis of nanoparticles by precipitation . uniform and dispersed zno nanoparticles were prepared by the two methods because zn2 + of conformation crystal was flee slowly and the supersaturation was well controlled . the problem which zno nanoparticles are wide size and agglomerative was solved 本文根據均相沉淀法合成納米粒子的原理,采用絡合沉淀法和沉淀轉化法合成納米氧化鋅。這兩種方法利用溶液中的構晶陽離子zn ~ ( 2 + ) ,緩慢地釋放出來,有效地控制了溶液中的過飽和度,可以得到粒徑均勻、分散的納米氧化鋅,解決現有制備工藝中納米氧化鋅粒徑分布寬、易團聚的問題。

Because of the rapid development of urban economy and the agglomerative the which is higher than that of general cities , big cities are developing at a surprising speed and their scale and number are increasing rapidly the development of big cities also leads to a series of urban illness such as the deteriorative residential condition , traffic congestion and urban environment aggravation , so researching urban structure pattem - is an important subject of modern urban planning 由于城市經濟的高速發展和具有比一般城市更高的“集聚效應” ,大城市以空前的速度迅速發展,城市的數量和規模急劇增長。但是,大城市的高速發展也導致了諸如居住條件惡劣、交通擁擠、城市環境惡化等一系列“城市病”的產生。

The second part deals with the relationship between agglomerative effect and suburb urbanization . on the basis of the study on the connotation , classifications , causes of formation and functions of suburb urbanization , by analyzing economy and diseconomy of agglomeration , the paper emphasizes the research on the impacts that the agglomerative effect makes to the behavior and location choices of enterprises and residents , which lead to the conclusion that the agglomerative effect is the main dynamical mechanism of suburb urbanization 從聚集效應入手,對郊區城市化進行了一般的經濟學分析,在研究了聚集效應的涵義、分類、成因和作用的基礎上,通過對聚集經濟與聚集不經濟的分析,著重研究了聚集效益對廠商、居民行為的影響以及對廠商與居民的區位選擇的影響,從而說明聚集效應是郊區城市化的主要動力機制。

The basic idea for hierarchy - based method is that creating and maintaining a tree of clusters and sub - clusters according to some kind of criterion to measure the distance of clusters , the procedure will be sloped until some terminal conditions are satisfied . hierarchical clustering method can be further classified into agglomerative and divisive hierarchical clustering , depending on whether the hierarchical decomposition is formed in a bottom - up or top - down fashion . most hierarchical clustering methods can produce the better results when the clusters are compact or spherical in shape . but they do not perform well if the clusters are any shape or there are outliers . a main reason is that the most hierarchical clustering methods employ medoid - based measurement as distance between clusters 基于層次方法的聚類的基本思想足:根據給定的簇間距離度量準則,構造利維護一棵由簇利子簇形成的聚類樹,直至滿足某個終結條件為止。根據層次分解是自底向上還是自頂向下形成,層次聚類方法可以分為凝聚的( agglomerative )和分裂的( divisive ) 。人多數層次聚類算法在緊密簇或球形簇結構下能夠產生較好的聚類效果。

In the meantime , we could also see that some old industrial bases built under planned - economy system in our country are showing a relatively poor behavior in the innovative efficiency , products competitive - power and district development , although they look like a industry agglomerative region . why is it like this ? do our economists make a mistake of the theory 但與此同時,我們也看到我國一些計劃經濟體制下建立起來的老工業基地,盡管其工業特征從表面看來似乎是產業集聚的形式,但是其在創新效率、產品競爭力和區域發展上的表現都不盡如人意,難道是經濟學家們把理論搞錯了,但是為什么國外的產業區又有著如此良好的發展形勢

Since 2000 , the inequality is at a high level . from the effective analysis of industry on regional economical inequality , two conclusions can be drawn : 1 . structural effectiveness is not the main reason for regional inequality ; 2 . agglomerative effectiveness is the important factor for the increase in regional inequality 從工業經濟對地區經濟差距的效應分析中得出如下結論: ( 1 )工業經濟的“結構效應”并不是影響地區經濟差距的主要因素; ( 2 )工業經濟的“集聚效應”是影響我國地區經濟差距變化的因素。

Agglomerative effectiveness : the effect on regional economical inequality because of industrial agglomeration . in order to show the effects of industry on regional inequality , the model of panel data is applied to analyze the relationship between industrialization and economy growth . , which is helpful to estimate whether the tendency of growth is convergence and the structural effectiveness . the time series model is used to analyze the effect of industrial agglomeration on regional inequality , where gini coefficient is taken as the index of industrial agglomeration 為了更清楚地把握工業在地區差距上的效應,本文用面板數據模型分析工業化程度和經濟增長之間的相關關系,從而判斷區域經濟發展趨勢是否收斂,工業在“結構效應”方面的影響;計算表示工業集聚程度的基尼系數,通過時間序列模型分析工業集聚對地區經濟差距的“集聚效應”影響。

A variety of methods including the tabular comparison of data , the tabular comparison of similarity coefficient , the nearest neighbor method and the group - average method of hierarchical agglomerative classification were applied to investigate the forest communities in meizi lake area 森林植被樣地中以喬木層樹種的重要值為指標,采用紙條排隊法、群落相似系數分類法、最近鄰體法、組平均法對梅子湖森林植被樣地進行數量分類。

By way of a large number of experiment detection , the technology parameter for when pressure 4 ~ 6atm and time 4hour can be prepared out to form the soft agglomerative state product 通過大量的實驗檢測,確定工藝參數為壓力4 6atm 、時間4hour時,能夠制備出形成軟團聚狀態產品。

In this paper , certain analysis on structural effectiveness and agglomerative effectiveness which are been done in order to find the reason for the increase of regional inequality 對于這種地區差距擴大的原因,本文試圖從工業的“結構效應”和“集聚效應”方面作出分析。

And this method can be divided into agglomerative and divisive hierarchical method with the time complexity of o ( n ) according to the decomposition process , e . g 根據層次的分解如何形成,層次的方法又分為凝聚的和分裂的方法,如birch算法。其計算其復雜度為o ( n ) 。

To improve the dispersivity of particles , research the agglomerative mechanism that the nanometer powder aspect universally exists to the liquid phase 為改善顆粒的分散性,對液相合成納米粉體普遍存在的團聚以及相應機理進行了探討。

Another distinction often made in the literature of numerical taxonomy is that between divisive and agglomerative approaches . 在文獻的版值分類方法中,還存在另一個區別,即劃分法和聚合法。
