Today, they survive precariously in a few patches, having retreated from 95% of their former domain, in the face of relentless human pressures: clearing of land for farming and grazing, woodcutting for fuel and timber, over-hunting of prey, and killing of tigers themselves.

而今天，老虎已经从其95%的栖息地上绝迹，仅仅在一些零星的地域苟延残喘，这一切的罪魁祸首正是人类无情的重压：为了耕作和放牧而清除森林，为了燃料和木材而砍伐树木，过度捕猎老虎的食物，甚至直接杀戮老虎。

Results show that ammonia volatilization was not detected in all the treatments during the tomato growing season. It was presumed that ammonia partial pressures on the surface soil were lower than the detection limit of the method, as a result of the low ammonical N concentration and low pH in the surface soil.

结果表明，番茄生长期间全部处理均未检测到氨挥发，其原因是土表氨分压低于检测灵敏度，较低的氨分压是由于表层土壤的铵态氮浓度和pH都不高所致。

The genetic variation among the natural populations of ginkgo revealed by Nei"s analysis , Shannon"s information index analysis and analysis of Molecular Variance ISSR :Gst=0.1955,(= 0.1903,φST= 17.63%;RAPD:Gst=0.2882,= 0.2949,φST=36.69% was greater than other kinds of anemophilous plants. The genetic differentiation among populations might be caused by human selective pressures and barriers of geography.

3Neis遗传多样性分析、香农信息指数分析和AMOVA分析所揭示的银杏居群遗传分化水平ISSR ：Gst=0.1955，= 0.1903，φST= 17.63%；RAPD：Gst=0.2882，= 0.2949，φST=36.69%，高于一般风媒植物，可能是地理阻隔和人为选择造成的。

This paper makes a systematic study of EOS and anharmonic thermodynamic properties for solid substance system at high temperatures-high pressures by using phenomenological method.

本文采用唯象的方法对高温高压下固态物质系统的EOS及相关的非简谐热力学性质作出了系统地研究。

After another six months, during which time the Anolis lizards grew increasingly arboreal, selective pressures were exactly the opposite: Survivors were now characterized by having shorter legs on the experimental islands as compared to the control islands.

又过了六个月后，当Anolis蜥蜴日益出现树栖习性，选择的压力变得完全相反：现在，比较起对照岛屿，在实验岛屿上，生存者表现出具有更短的四肢。

His argument is that the unusual history of the Ashkenazim has subjected them to unique evolutionary pressures that have resulted in this paradoxical state of affairs.

他认为正是异常的历史环境强加给了德系犹太人独有的进化压力，才导致了这些看似奇怪的现象。

In the present study, tungsten oxide nanomaterials were synthesized by a modified plasma arc gas condensation technique. The effects of the plasma currents (70~90 A), chamber pressures (200~600 torr), production time（3~12 min）, oxygen partial pressure Ar:O2（1~6:1）and plasma including the hydrogen（0~10 %）on the preparation of tungsten oxide nanostructures were investigated. Pre-treatment on the tungsten oxide nanorods for surface modification was investigated by atmospherical plasma jet. The optical, filed emission, and gas sensing characteristics of tungsten oxide nanopowders were also examined.

本研究系利用电浆电弧气凝合成法来制备氧化钨奈米材料，分别探讨不同腔体压力（200~600 torr）、电浆电流（70~90 A）、制备时间（3~12 min）、氧分压Ar：O2（1~6：1）、电浆气含氢量（0~10 %）对於产物的形貌、相态影响，并使用常压低温电浆设备对氧化钨奈米棒进行表面处理，且针对氧化钨奈米材料的光学、场发射以及使用自行组装气体感测量测设备量测其气体感测特性。

Riding awave of pride and patriotism after hosting the Olympics,China's communist leaders face few of the public doubts or budgetary pressures constraining such programs elsewhere.That has allowed them to fuse political will and scientific gusto in astep-by-step process that could one day see Chinese astronauts landing on the moon.

伴跟着乐成举办奥运的高昂的平易近族自豪感和热爱自己的国家主义情结，中---共领导者在几乎没有公家质疑或预算压力制约的条件下，借此项目将许多人的政治意愿和科学热情大好地融合在一路，步步为营，并终将某天把中国的宇航员送上月球。

The result indicates that Bassia rapa L. 65%, 95% alcohol extract and water extract can prolong the survival time of mice in hypoxia under ordinary pressures significantly. It can also prolong the survival time of mice with acute cerebral ischemia and sodium nitrite significantly, and increase the number of erythrocytes and the content of hemoglobin. It demonstrates that Bassia rapa L. extract has anti-hypoxia activity.

结果表明，芫根水提取物、65%乙醇提取物及95%乙醇提取物均能明显延长模型小鼠在常压缺氧、急性脑缺血性缺氧及亚硝酸钠中毒时的存活时间，并可增加外周血象中红细胞数与血红蛋白含量，显示芫根提取物具有抗缺氧活性。

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
