本次全面回顾了省内外学者近三十年来对河南省恐龙化石的发现及研究历史，赋存化石的中生代盆地地质构造背景、地层分布、古地理环境等的研究成果。

Through field survey and the investigation of the aerial photograph,we have found that the geographical landscape of the seashore belt shows distinct photographical characteristics on the aerial photograph.

通过实地调查和航片研究，发现海岸带地理景观在航片上具有明显的影象特征，其中尤以海岸动力地貌和盐土植被在航片上最富有特征，而海岸地貌和植被与土壤的性质和分布又具有很好的相关性。

These results demonstrate that the Chinese seed plant genera correspond well to recognized vegetation zones and floristic regions, providing further support for the current phytogeographic definitions.

中国种子植物属的地理成分的分布格局与现行的中国植被分带和植物区系分区密切匹配，支持现行的中国植被分带和植物区系分区方案。

Occurrence records from 1864 locations and 34 environmental variables from Daymet datasets were gathered, four modeling methods including Logistic Regression, Classification and Regression Trees, Genetic Algorithm for Rule-Set Prediction and maximum entropy method were used to generate potential geographic distributions for Dreissena polymorpha in the continental USA. Then three statistical criteria including area under the Receiver Operating Characteristic curve, correlation and Kappa were calculated to evaluate the performance of the models, followed by analyses of major variable contributions.

论文以1864个美国外来入侵物种斑马纹贻贝定点发生数据和开放式基础地理信息数据库Daymet的34个环境变量为主要信息源，采用逻辑斯蒂回归、分类与回归树模型、基于规则的遗传算法、最大熵法4种途径，建立美国大陆部分潜在生境预测模型，从接受者运行特征曲线下面积、Pearson相关系数、Kappa值3个方面来检验模型预测精度，在此基础上分析斑马纹贻贝的空间分布规律及其环境影响因素。

This scheme combined the q-composite random key predistribution scheme and introduced the location information to enhance secure connection probability between nodes.

该方案结合q-composite随机密钥预分布模型，并且通过引入地理位置信息，有效提高了节点之间安全连通的概率。

Objective To understand the association between the genetic variation of hantavirus and genetic differentiation of Rattus norvegicus population from Beijing.

目的 了解北京地区褐家鼠不同地理种群遗传多态性与该地区汉坦病毒基因变异及其分布可能存在的关联。

This resuit may be related to differences in selection pressure exerted on species by their habitats with different distribution ranges.

说明在大尺度上遗传距离与地理距离相关而在小范围内则无上述关系，该结果可能与位于不同分布区内的物种所承受的生境选择压力不同有关。

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。
