For stratified and cluster sampling with inappreciable differences, estimate precision becomes poor.

对于分层抽样和整群抽样，当群体间的差异、群内个体间差异均不显著时，其估计精度往往都很差。

For further interpretation and determination of the cluster numbers of each UPGMA dendrograms, minimum distance statistics, was therefore applied. The results showed that the application of butachlor altered the composition of diazotrophic and eubacterial communities without recovery to the inceptive state after 100 days of rice cultivation.

为更进一步演绎集群分析结果，采用最小距离法（Minimum Distance，简称MD）决定UPGMA 图谱的分群数目，所得结果显示，丁基拉草的施用可影响游离固氮菌及真细菌菌族群之菌相组成，且经100天的水稻种植期后，未能恢复成原有的菌相状态。

Indusium The flap of tissue, derived from the placenta, that encloses the developing sporangia in the sorus of a fern.

囊群盖：是一种起源于胎座的瓣片状组织，覆盖在蕨类植物孢子囊群中正在发育的孢子囊上。

The sorus is covered by a flap of tissue, the indusium.

囊群上方具有囊群盖，可将其覆盖。

Sori 1-5 pairs borne on the lower surface of ultimate lobes at the end of basal veins; indusium dehiscent in two equal halves when mature.

孢子囊群1-5对，生於末回裂片下面近基部小脉顶端；囊群盖成熟时对开2裂。

In this paper, the concept of industrial clusters and action, and then an analysis of industrial clusters pomleo jiangyong the current situation and problems, for these issues proposed countermeasures.

本文提出了产业集群的概念和作用，然后分析了江永香柚产业集群的现状及存在的问题，并针对这些问题提出了对策。

In recent years, the theory of infinite dimensional simple Lie algebra has become an important branch in Lie theory.

近年来无限维单李代数的结构理论以及表示理论已经成为李代数研究中的重要分支，无限维单李代数的构造，自同构群的确定，同构分类，二上同调群的计。。。

Six populations of Xiphinema elongatum and one population of X. insigne, new recorded species in Kinmen, were isolated from the rhizosphere of pine, persimmon, guava, litchi, sweet orange, sugar apple and loquat from 2001 to 2003. One population of Xiphinema sp.

自2001至2003年问，由金门岛地区的松树、柿子、番石榴荔枝、甜橙及番荔枝等的根圈土壤中分离鉴定6群Xiphinema elongatum ，在枇杷上则发现1群 Xiphinsigne，而此二种剑线虫都是该地区的新记录种。

An integer coded hybrid particle swarm optimization algorithm which incorporates the crossover and mutation operators of Genetic Algorithm with basic particle swarm optimization is proposed to solve the model, and a C ++ code is programmed.

同时提出基本粒子群优化算法与遗传算法交叉、变异算子相结合的整数编码的混合粒子群优化算法来求解该选址模型，并编制了相应的C++程序。

The main tool is the notion of theLipschitz condition with positive nondecreasing integrable function L-average along thepieces one-parameter subgroup which includes the classical Lipschitz condition as well as theγ-condition as special cases.

我们在研究中引入沿着任意段单参数子群的关于取正值非减可积函数L-平均的Lipschitz条件。从而把李群上的Kantorovich定理及Smale理论放在统一的形式下进行研究。

In the United States, chronic alcoholism and hepatitis C are the most common ones.
