狍的乐园——内蒙古赛罕乌拉国家级自然保护区

狍（Capreolus copreolus）隶属于偶蹄目、反刍亚目、鹿科、狍属，义名矮狍、野狍等，是一种珍贵的野生鹿科动物。狍广布于欧亚大陆的中部和北部，在我国分布于东北区大兴安岭亚区、长白山地亚区、松辽平原亚区，华北区黄淮平原亚区、黄土高原亚区，蒙新区天山山地亚区，青藏区青海藏南亚区；边缘分布于西南区西南山地亚区，华中区东部丘陵平原亚区。     

动物地理区划的聚类分析

用聚类分析方法分析了中国及陕西省动物地理区划方案,结果表明聚类结果与区划方案基本一致,但台湾亚区和南海诸岛亚区与中国大陆动物区系差异较大。因此,应重新考虑这两个亚区的区划级别;属于蒙新区的东部草原亚区的归属问题也值得考虑;省,州级动物地理区划应较多地考虑生态地理的条件及其原则。     

宁夏草原昆虫区系分析及生态地理分布特点

宁夏草原昆虫已知21目207科1374种,选择其中有代表性的金龟类（Scarabaeoidea）、蝗虫类（Othoptera）、蝶类（Rhopalocera）、夜蛾科（Noctuidae）和蝽科（Pentatomidae）5个类群,结合宁夏生态地理实际分析其区系组成特点,并对草原昆虫的一般地域分布和垂直分布进行基本分析,据此提出宁夏昆虫生态地理区划的初步意见,即3个区：六盘山森林草原昆虫区;黄土高原干草原昆虫区;荒漠半荒漠草原昆虫区。荒漠半荒漠草原昆虫区又分3个亚区：贺兰山、罗山草原昆虫亚区;河套绿洲草原昆虫亚区;荒漠半荒漠草原昆虫亚区。     

内蒙古大青山国家级自然保护区部分区域的兽类物种多样性

内蒙古大青山国家级自然保护区是蒙古高原中温型典型草原区和大青山以南暖温型草原的交汇处,动物区系属于古北界、中亚亚界、蒙新区、东部草原亚区,动植物种类丰富多样.为掌握大青山国家级保护区兽类物种多样性的本底资料,并为相关物种的保护提供基础资料,2018年7～11月对大青山国家级自然保护区内的包头市九峰山林场、呼和浩特市大青山林场、卓资县上高台林场进行了调查.结果显示:共获到野生兽类物种23种,隶属4目9科,占该地区兽类物种总数的69.7%.Ⅰ级重点保护动物1种,Ⅱ级重点保护动物4种.1种被评估为极危种,1种列为濒危种,3种被评估为易危种,2种列为近危种.兽类中相对丰富度居于前三位的分别为狍(RAI=82.4%)、中华斑羚(RAI=8.4%)、亚洲狗獾(RAI=8.3%).常拍种为狍(CR=10.36%),较常拍种为中华斑羚(CR=1.7%)、亚洲狗獾(CR=1.1%),偶拍种为豹猫(CR=0.4%)、赤狐(CR=0.7%).通过比较发现,九峰山林场各兽类种群密度最高,狍、草兔、花鼠为常见种,说明兽类多在生境复杂、高度空间异质性以及充足食物的栖息环境中有着较高的活动强度.     

宁夏两栖爬行动物区系分析及地理区划

现已知宁夏有1目3科3属6种两栖动物;2目8科13属19种爬行动物(表1)。爬行动物中的高原蝮是宁夏新纪录。作者分析了宁夏两栖爬行动物的区系和地理分布,结合其它自然因素,拟把宁夏及其邻缘省区的部分地区划分为6个动物地理省(图1,表2)。本文还讨论了华北区,蒙新区两个区以及蒙新区的东部草原亚区与西部荒漠亚区在宁夏及近邻地区的界线。     

宁夏哺乳动物地理分布的聚类分析

用组平均法对宁夏哺乳动物地理分布区进行聚类,６ 个动物地理州在距离系数为０．３８７０ 时聚为４ 个类群,在距离系数为０．５１４９ 水平聚合为２ 个类群组．聚类结果与中国动物地理区划中宁夏跨２ 个动物地理区及宁南、宁中北分属华北区黄土高原亚区和蒙新区东部草原亚区的划分相吻合,而与宁夏西北边缘的贺兰山地和腾格里沙漠东南缘同属蒙新区西部荒漠亚区的划分不吻合．文章对聚类结果作了分析,比较了应用不同匹配系数公式对动物地理分布聚类结果的影响．     

中国小异长足虻属昆虫区系分析

通过对中国已记载的小异长足虻属昆虫162种进行区系分析研究,结果发现:中国小异长足虻属昆虫在世界动物地理区划中有5种分布型,以东洋界为主,其次为古北界;在中国动物地理区划中有14种分布型,以华中区为主;中国小异长足虻属昆虫广布种少,特有种多;跨界分布的种类较少,跨中国动物地理区分布的种类也较少,说明了中国小异长足虻属昆虫分布地狭窄,不善于扩散。     

吉林省西部白城地区动物生态地理群与动物地理区划研究

本文是在吉林省西部多年调查掌握的大量鸟兽资料的基础上,根据动物区系特点及其分布规律,对吉林省西部白城地区进行了省一级动物地理区划,并就动物生态地理群作了划分,最后,对全国亚区一级动物地理区划界线问题,提出了一些看法。     

河北省陆栖脊椎动物分布之研究

掌握某一地区动物的区系和生态分布,对于深入地阐明其生态地理分布规律,制定合理而充分地开发动物资源,以及对珍稀、濒危动物种类的保护和恢复规划等方面均具有重要的意义。我省在动物地理区划中的位置虽属于华北区,但是由于太行山系为动物地理分布的“走廊”,以及河北大平原无明显的“地理屏障”,所以,东洋界和古北界的动物在我省为一混杂地理带,故动物的区系成分和种类都比较复杂。迄今关于我省陆栖脊椎动物地理分布的系统全面的专题研究尚未见有报导。笔者根据多年来的实地考察并参阅有关的文献资料,写成此文,谨供有关部门参考。

Markedness and its Interpretation in Language Use

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.     

Features of Women's language

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women＇s language from these perspectives： pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women＇s language, more attention should be paid to language use in social context. What＇s more, the linguistic phenomena in a speaking community can be understood more thoroughly.     

低渗透非均质砂岩油藏启动压力梯度研究

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。     

On Tragic Consciousness In The Works By Ernest Hemingway

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.     

Achieving Unusual States of Matter Under High Pressure

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-     

Exchange-Correlation and Electronic Excitation Energies from Pairing Matrix Fluctuations

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-     

Density Functional Theory for the Response of Periodic Systems to Electric Fields Based on the Vector Potential Approach

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that     

On the Thermodynamic Limit for Responses to Static Electromagnetic Fields

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the
