Furthermore, the experiences of artificial breeding and farming showed that different geographical populations of Meretrix clam are also substantially different in growth rate and the ratio of shell weight to soft-body one.

由于我国海岸线漫长、地形复杂，因长期地理隔离和生境不同，导致不同海域的文蛤在壳表形态和颜色、花纹图案等外观特征上均存在显著差异；另外，从多年的养殖实践中也发现，我国文蛤不同地理群体在生长速度、壳肉重比率等重要经济性状上也存在着显著差异，而这些性状的稳定性差异必然依赖于其分子遗传结构的变异。

Together with previously reported α neurotoxins in Naja kaouthia and Naja atra, it was found that the α neurotoxins of Naja kaouthia in Yunnan Province were similar to those of Naja atra in Zhejiang and Taiwan Provinces, but different from those of Naja kaouthia in Thailand.

另外泰国孟加拉种眼镜蛇蛇毒中则以长链神经毒素为主。这种现象很难用种群发生的前后或者地理距离的长短来解释，而可能与地区间的气候、地理环境或者眼镜蛇的食物差别相关。

Arc/Info is a generic nonapplication specific approach to geographic information systems, allowing the software to address virtually any geographic application.

Arc/Info是地理信息系统中一个普通的、非应用性、特定的方法，允许软件从事任何地理的应用。

In this paper, based on satellite altimeter oceanographical remote sensing and computer technology, several important functions of marine geographical information system are implemented by the acquisition, retrieval, visualization and storing of macroscale sea surface wind data.

本论文基于卫星高度计海洋遥感和计算机技术，通过对大尺度海洋风场数据的获取、处理、可视化、存储等工作，结合地理信息系统和海洋学研究，实践了开发型海洋地理信息系统研发过程中几个重要的具体环节。

The problems have been attributed to difficulties in the interpretation of the significance of morphological characteristics used to classify palaemonid shrimp and have hindered the development of stable classification systems.

本研究以中国境内分布的沼虾属种类为主要研究对象，利用DNA测序、PCR-RFLP技术和ISSR技术等分子生物学实验手段，运用支序系统学与分子进化生物学理论及分析方法，以地理群体为基本研究单元，展开从地理种群-物种-属的逐级水平的系统学研究。

The development of computer technology and the popularization of GIS greatly promote the innovation of palaeogeographic reconstruction, which provide a more convenient and efficient software platform.

同时，计算机技术的发展以及GIS技术的推广，极大地推动了古地理再造方法的革新，为古地理再造提供了更加方便、高效的软件辅助平台。

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

这两幅古地理图的最大特征是定量，即每个古地理单元的划分和确定都有确切的定量和单因素图和数据为依据。

Palaeogeography is a branch of geosciences, which studies natural geographical features in the geological history. The research targets are the evolution history of oceans and continents, and the distribution and characteristics of the internal palaeogeographic units.

古地理学是研究地质历史时期自然地理特征的地质科学，其研究目标是海洋和陆地的变迁历史及其内部古地理单元的分布和特征。

With the combination of the key points in the areas, the paper works out sequence lithofaeies Palaeogeography map and studies sequence Palaeogeographic evolution and distribution of various Periods.

点面结合，首次编制了以超层序为编图单元的层序岩相古地理图，揭示了不同时期层序岩相古地理的演化和分布规律。

Palaeogeographic database can be established with various information acquisition and management methods. Palaeogeographic information of multi-source and multiscale can be organized with a spatial data model. Palaeogeographic environments can be reconstructed with the 3D modeling and a virtual reality technique. Palaeogeographic research achievements can also offer better service with the development of internet technology.

多种多样的信息采集和管理方法可以建立不同时期的古地理学综合数据库；空间数据模型为组织多来源和多尺度的古地理信息提供框架；三维数据建模和虚拟现实技术为古地理环境重建营造了必要条件；互联网技术的发展可使古地理学研究成果更好地为用户服务。

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。
