The results showed that seeds of Ocimum basilicum Linn.

栽培试验进行栽培密度和施肥对比两种试验；栽培密度试验设20cm×30cm，30cm×40cm，40cm×50cm 3种处理，每种处理3个重复；施肥对比试验设每公顷施复合肥0kg、450kg，675kg，900kg，4种处理，每种处理3个重复。

Five species: one species endemic to tropical Africa, three endemic to Madagascar, one pantropical; one species in China.

种：热带的非洲特有的1种，马达加斯加特有的3种，1种泛热带；一种在中国。

About 50 genera and 1300 species: pantropical with center of diversity in S and SE Asia, some species in America and subtropical and warm-temperate Asia; 20 genera and 216 species (141 endemic, four introduced) in China.

大约50 属和1300种：泛热带分布，多样性中心位于亚洲南部和东南部，一些种类分布于美洲和亚洲亚热带和暖温带地区；中国有20属和216种(141种特有，4种为栽培种)。

The natural enemies group, neutral arthropod group and phytophagy arthropod group of the two sub-systems were respectively analyzed and have found that all types of arthropods of the two sub-systems can be divided into three different types of groups. The first group is which living in two habitats and the species current is few impacted by the changes of habitats; The second group is which can living in two habitats in turn ,but can transfer to another in the time the habitats was deeply disturbed ;The third one can only living in one habitats and can make the another habitats as a temporary habitats.

两个亚系统的天敌类群、中性节肢动物类群、植食性节肢动物类群分别进行分析发现两个亚系统的各类群节肢动物均可划分为三种不同类型，第一种为栖居于两种生境且物种流受生境变化影响较小类群；第二种为可依次栖居于两个不同生境，生境的变化对其物种流产生较大影响；第三种为栖居于某一单一生境，但可将另一系统作为某一虫态的临时栖境。

The two-dimensional structural units (such as silicon-oxygen tetrahedral sheet, octahedral sheet), interlayer space are assembled according to the sphere close packing manner, and the close packing layers parallel to {0001}. There are several mechanisms to release the difference in size while the silicon-oxygen tetrahedral sheet and octahedral sheet assemble the TO and TOT-type structural layers. The two types of structural layers with different interlayer space fitted together in six kinds of assembling modes and formed six kinds of crystal layers. The combinatorics analysis of the two-dimensional structural units revealed that there may be 28 kinds of TOT type interstradified minerals in six kinds of polysomatic assembling modes of interatradified structure. The structural layer is symmetrical for octahedron sheet in the structure of interstratified minerals and shows polarity characteristics.

结果表明，不同二维结构单元体（包括硅氧四面体片、八面体片、层间域的构筑基本符合球体紧密堆积原理，紧密堆积层平行{0001}；四面体片与八面体片构筑TO和TOT结构层时采取多种机制消除二者在二维尺寸上的差异；两种模式的结构层与不同类型的层间物组装形成六种组装模式的晶层；并通过二维结构单元体的组合规律的分析，计算出可能存在的28种TOT型间层结构，它们分属于6种间层结构多体性组装模式；间层结构中，结构层对于八面体片是不对称的，并在属性上表现出极性特征；间层矿物的晶层类型可用6种多体性组装模式加以表达。

The Dongting Lake area is the largest lacustrine wetland ecosystem in China,where biological resources are very plentiful,which include 1428 species of plants,216 species of birds, 119 species of fishes,27 species of amphibians and retile,22 species of mammals and a great number of other wild living things.

中文摘要：洞庭湖湿地是我国最大的淡水湖泊湿地生态景观系统，生物资源十分丰富，其中植物资源 142 8种，鸟类资源 2 16种，鱼类资源 119种，哺乳类 2 2种，两栖爬行类 2 7种及其它大量的野生生物资源。

Coffee belongs to Rubiaceae Family, an evergreen shrub or short sarbor, and it has many species, among which the widely planted ones are :Arabica, Robusto, and Ethiopean ,while one of the arabica species named"Aromatic Coffee" is mostly prolific, accounting for about 80 percent of the total output of coffee.

咖啡是茜草科咖啡属的多年生常绿灌木或小乔木，种类很多，被广泛种植的有小粒种、中料种、大粒种和埃塞尔萨种，其中被称&香咖啡&的小粒咖啡种产量最多，约占咖啡总产量的百分之八十以上。

It's shown that Carex stenocarpa, Polygonum viviparum, Kobresia capillifolia and Festuca ovina's niche breadth are wider; Potentilla sp., Polygonum viviparum, Geranium pratense and others' niche breadth are more narrow. The former belong to extensive species, it is high in adapting to soil acid and salification, the latter belong to equilibrium species, it's adaptability is weaker than the former.

结果表明，细果苔草、珠芽寥、线叶嵩草、羊茅等建群种和优势种的生态位最宽，适应土壤酸碱和盐渍化能力强，为泛化种；委陵菜、千叶蓍、草原老鹤草等伴生种生态位窄，适应酸碱和盐渍化能力弱，为特化种。

By investigation to insect communities of the Trifolium repens in the north area in Henan province, the familiar insect categories have been found out which including 12 orders, 37sections, and 80 species; In another word, there are 50 kinds of the harmful pests, 22 kinds of the natural enemy insects, 2 kinds of the activity insects and 1 kind of saprophagous insect.

通过对河南省豫北地区白三叶草坪昆虫群落的调查与普查，摸清了其常见的昆虫种类：12个目，37个科，80个种；计有害虫50种，害虫天敌22种，活动性强的昆虫2种及腐食性昆虫1种。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
