亚目

Selaginellales An order of the Lycophyta containing the single living genus Selaginella, sometimes called spike-mosses, with about 700 species, found worldwide, but especially in the tropics.

卷柏目：为石松亚门下一目，该目仅有单属卷柏属，常被称为卷柏。这类植物有700多种，分布广泛，以热带居多。

Result 10 308 insects were identified, belonging to 9 orders, 43 families, 68 species of Insecta and I families, 1 species of Arachnida. The result revealed that the individuals of the pest sub-community were more than that of the natural enemies sub-community, the dominant concentration and dominance of the pest sub-community were the biggest, diversity index of the natural enemies sub-community was more than that of the pest sub-community.

结果］共调查昆虫10 308头，分属于昆虫纲9个目、43科6、8种以及蛛形纲1科、1种；野生植物害虫亚群落的物种个体数多于天敌亚群落的个体数，害虫亚群落的优势集中性和优势度最大，天敌亚群落的多样性指数大于害虫亚群落。

Bivalvia could be subdevied into 2 major groups, Heterodonta and Pteriomorphia.

异齿亚纲内，海螂目单系发生，而帘蛤目是并系发生的。

There are a total of 34,782 individuals belonging to 15 orders, 102 families were found in this study. And the dominant groups among them were Myriapoda、Lycosidae、Miridae、Delphacidae、Cicadellidae、Aphidoidea、Margarodidae、Geometridae、Noctuidae、Olethreutidae、Braconidae、Chrysopidae、Coccinellidae.

调查共发现节肢动物个体34782个，分属3纲、15目、102科，其中优势类群主要是多足纲、蛛形纲狼蛛科、半翅目异翅亚目的盲蝽科，同翅目的飞虱科、叶蝉科、蚜科、蚧科，鳞翅目的尺蛾科、夜蛾科、小卷蛾科，膜翅目的小茧蜂科、小蜂总科，脉翅目草蛉科、鞘翅目瓢虫科。

It comprises two species,Dianulites hexaporites,Orbiramus grandis sp.nov.of trepostome esthonioporines,and one species,Prophyllodictya putilovensis Lavrentjeva of cryptostome ptilodictyines.

这个苔藓动物群由变口目爱沙尼亚苔虫亚目的两个种：Dianulites hexaporites，Orbiramus grandissp.nov。和隐口目翼网苔虫亚目的一个种：Prophyllodi-ctya putilovensisLavrentjeva组成。

Palmlike gymnosperms: includes the surviving order Cycadales and several extinct orders; possibly not a natural group; in some systems considered a class and in others a subdivision.

棕榈状裸子植物；包含现在还幸存的苏铁目和其它几个已灭绝的目；可能不是一个自然群体；在某些分类中，被视为一个纲，在另外一些分类中则为一个亚部。

The sequence variation analyses showed that there are 236 variable and 221 parsimony-informative in the aligned 605 nucleotide sites, in addition, the relative frequenencies of four nucleotides were not equal an this fact showed that the base compositions were biased. The results of phylogenetic analyses showed:(1) the phylogenetic relationships of the Cypraeidae taxa was basically in consistent with morphology-based ones;(2)Cypraeovulinae was monophyletic in all trees, whereas Nariinae and Cypraeinae were not;(3)the monophylies of Mauritia, Palmadusta, Erosaria, Monetaria, Staphylaea and Pustularia were strongly supported by molecular data;(4)Meyer's speculation that Chelycypraea came out from Luria were also supported.

结果表明：(1)宝贝科28种动物的分子系统树大部分与形态学分类一致；(2)在系统树上，疹贝与鼻贝亚科的其它分类群的距离相隔较远，提示它们之间有较远的亲缘关系，建议将疹贝属列入宝贝亚科；(3)卵宝贝亚科包括希达贝、脊焦贝、筛目贝、拟枣贝、焦掌贝以及呆足贝等共计15个属，它们在系统树上构成独立的一个大支系，构成单系群；(4)支持Meyer将龟甲贝从禄亚贝总属中分离出来的观点，但龟甲贝和林西那贝之间的系统发生关系及其分类地位还有待于进一步探讨。

In former classifications a division of Malacostraca; superseded by the orders Mysidacea and Euphausiacea.

在以前的分类中是软甲亚纲的一个部；现在被糠虾目和鳞虾目取代。

Relationship between DNA content and evolutionary degree DNA contents of bivalves were analyzed statistically with SPSS software at subclass, order, family and species grade respectively. Significant difference was detected between mean values of two subclasses according to the result of T-test. The DNA content of Heterodonta (3.77pg) was distinctly larger than that of Pteriomorphia (3.14pg). It was concluded based on ANOVA that the general trend of DNA content was to change from lower to higher values associated with evolution at higher taxonomical classification, i.e.

核DNA含量与进化地位的关系运用SPSS统计软件，在亚纲、目、科以及种4个分类等级上对双壳贝类的核DNA含量进行了统计分析。T检验结果显示，两亚纲核DNA含量的平均值有明显差异，异齿亚纲的核DNA含量平均值(3.77pg)显著大于翼形亚纲(3.14pg)，该结果表明，核DNA含量在较高的分类等级，即亚纲上表现出随着进化地位的升高显著增大的趋势。

The former was monophyletic while the phylogenetic status of Pteriomorphia was ambiguous owning to the controversial position of Ostreidae.

与其他分子研究的结论不同，本研究分析结果支持现有的分类系统，即异齿亚纲可以向下划分为两个目：帘蛤目和海螂目。

We have no common name for a mime of Sophron or Xenarchus and a Socratic Conversation; and we should still be without one even if the imitation in the two instances were in trimeters or elegiacs or some other kind of verse--though it is the way with people to tack on 'poet' to the name of a metre, and talk of elegiac-poets and epic-poets, thinking that they call them poets not by reason of the imitative nature of their work, but indiscriminately by reason of the metre they write in.

索夫农 、森那库斯和苏格拉底式的对话采用的模仿没有一个公共的名称；三音步诗、挽歌体或其他类型的诗的模仿也没有——人们把&诗人&这一名词和格律名称结合到一起，称之为挽歌体诗人或者史诗诗人，他们被称为诗人，似乎只是因为遵守格律写作，而非他们作品的模仿本质。

The relationship between communicative competence and grammar teaching should be that of the ends and the means.

交际能力和语法的关系应该是目标与途径的关系。
