Genus and 40 species of Jurassic Pteriomorphia and Isofilibranchia from Northern Tibet were described in present paper. The data of genus and species of Jurassic Pteriomorphia and Isofilibranchia from Northern Tibet, Southern Tibet, and India were studied with cluster analysis respectively. The Jurassic palaeobiogeographic and palaeogeographic relations of these three regions were also discussed on the basis of the result of cluster analysis and analysis of the controlling factors of bivalve distribution.

本文记述了藏北侏罗纪双壳类Pteriomorphia和lsofilibranchia化石22属40种，对藏北、藏南及印度侏罗纪Pteriomorphia和Isofilibranchia的属和种分别进行了统计和聚类分析，以此探讨这三个地区之间的古生物地理关系，并进一步分析了控制侏罗纪双壳类分布的因素及讨论了藏北、藏南与印度这三大地块的古地理位置。

According to these, we can realize tectonic control, palaeogeographic pattern as well as palaeobiogeographic distribution of the Qinghai-Tibet Plateau in the early Paleozoic and also provided the materials to the cosmepolitical biostratigraphic contrast.

新建下奥陶统扎扛组和他多组，完善了藏北地区早古生代地层序列，为研究青藏高原在古生代早期的构造活动、演化、古地理分布格局及古生物地理区划提供了资料，也为世界性生物地层划分对比提供了依据。

Palaeogeography maps are the concentrated expression of the study of palaeogeography, and are the growth point of palaeogeography.

古地理图是古地理研究的集中表现，是古地理学的生长点。

The most important character of these lithofacies palaeogeography maps is quantification. Quantification means that the determination of each palaeogeography unit is based on the accurate quantitative data and the quantitative single factor maps.

这些岩相古地理图最主要的特征是定量，即每个古地理单位的划分和确定都有确切的定量资料与定量的单因素图。

It is based on the present writers' achievements of study and mapping of quantitative lithofacies palaeogeography of the Cambrian and Ordovician in North China, South China and Northwest China.

在对华北地区、华南地区和西北地区寒武纪和奥陶纪定量岩相古地理研究及编图成果的基础上，结合其他地区（主要是蒙兴地区、昆仑秦岭地区、西藏地区、海南岛和台湾地区）的地质资料，编制出了中国晚奥陶世岩相古地理图，并撰写出本文。

Other areas are less studied, and the secondary lithofacies palaeogeography units are difficult to be delineated out. The lithofacies palaeogeography maps of these areas are qualitative.

其他地区的研究程度较低，难以再划分出次级古地理单元，其古地理图都只能是定性的，其文字编述也只能是概略性的。

The basin's continental tectonic settings and its evolution of each phase is also discussed, and the lithofacies palaeogeographies of each phase are analyzed elementarily. At the same time, the tectonic palaeogeography and sedimentary basin evolution model diagrams are drawn.

分析和讨论了沉积盆地在各个阶段的构造背景特征及其演化过程，初步恢复了每个阶段盆地的岩相古地理格式，绘制了盆地的构造古地理格架图和沉积盆地演化模式图。

The Tianshan-Beishan Trough can be further divided into secondary lithofacies palaeogeography units, but other troughs are difficult to be subdivided.

天山北山槽地可分出次级岩相古地理单元，其他槽地的次级岩相古地理单元尚难以划分。

On the basis of a study of sequence stratigraphy, with the systems tract and related boundaries as the mapping unit and using the systems tract condensation method and instantaneous map production method, the authors have compiled the Permian sequence paleogeographic map of southwestern China and systematically elucide the characteristics of the Permian sequence paleogeographic evolution of the region.

文摘：在层序地层研究成果基础上，以沉积体系域和相关界面为编图单元，采用体系域压缩法和瞬时编图法，编制了西南地区二叠纪层序古地理图，全面系统地阐述了该区二叠纪层序古地理演化特征。

Zhongkai Agrotechnical College, Guangzhou 510 225, China）Abstract: The geographical distribution and the features of their environment of Chinese species of Paphiopedilum ar e reported.

摘 要：分析了国产兜兰属植物的生态地理分布特点和发展趋势及兜兰属植物的系统演化趋势与生态地理环境的关系。

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。
