变暖的

The United States is the world's largest polluter, accounting for 25% of all carbon dioxide emissions, a major cause of global warming, despite its population of just 4% of the world's total.

美国是世界上最大的污染排放国，尽管它的人口只占全球人口的百分之四，但二氧化碳排放量占全球总排放量的25%，而二氧化碳排放是引起全球变暖的主要原因。

The results suggest that under the background of global warming, the researches on the mechanism and variation of snow-storm and freezing rain should be strengthened, especially the researches on their premonitory characters; modern detect technique and instrument should be used to improve the ability of monitoring snow-storm and freezing rain, and skills and methods for forecasting snow-storm and freezing rain should be established and improved.

认为：在全球气候变暖的背景下，要加强雨雪、冰冻天气形成机理与变化规律的研究，特别是要加强其发生的前兆性研究；要充分利用现代先进的探测技术和手段，提高对雨雪、冰冻天气的监测能力；要建立和完善对雨雪、冰冻灾害天气时间发生、发展的预报技术和方法。

It should go without saying that it's important to travel conscientiously, not profligately, and to hang up your towel, out of courtesy to the staff as much as anything. But the notion that we can reverse climate change by giving up holiday flights is as daft as the joke circulating around the time of the Heiligendamm G8 summit that, as President Bush understood it, an escalation in the cold war might help in the fight against global warming.

不言而喻，重要的是旅行时要有责任心，而不是挥霍浪费，挂起你的毛巾，无论是处于对员工的礼貌还是其他但改变地球气候变化就要放弃假日航班的想法，就像在德国海利根丹姆举行的八国峰会期间流传的一个笑话一样可笑：在布什总统看来，冷战的逐步升级可能有利于对抗全球变暖的斗争

While it's impossible to prove conclusively the changes are the result of global warming, the evidence is so strong and other supportable explanations are lacking, Thomas said, so it is "statistically virtually impossible that these are just chance observations."

尽管现在还不可能作出结论这些变化是全球气候变暖的结果，但这证据如此有力，又没有其它的站的住脚的说法，从统计学上又不可能说这些是偶然观察到的？

Although there is a large of arid or semi-arid area and abundant plant source in North China,the globle warm and environment change made so many xerophil species face to huge challenges of unfavorable environment,especially,water stress.

中国北方地区因其独特的地理位置和气候条件，使该地区旱生植物资源非常丰富，但受全球气候变暖的影响，荒漠化程度日益严重，而这些旱生植物种群也将面临原有生存环境发生改变的严峻考验，其中，水分条件的改变是学者们普遍公认的重要环境改变之一。

"Our study shows that presering and restoring forests is likely to be climatically ineffectie as an approach to slow global warming," said Ken Caldeira, a co-author of the study from the Carnegie Institution. To preent climate change, we need to transform our energy system. It is only by transforming our energy system and presering natural habitat, such as forests, that we can maintain a healthy enironment.

&我们的研究表明，保存及重建森林好象是很无效的减缓全球变暖的方法&共同研究者，卡内基研究所的Ken Caldeira说，为了阻止气候变化，我们需要改造我们的能源系统，保存自然栖息地，例如森林，我们才能维护健康的环境。

Anthropogenic habitat fragmentation and widespread interruption of elevational forest corridors, which may increase as cloud levels rise with climate warming, cannot fail to impede successful range shifts, particularly for forest-dependent species with limited dispersal potential.

人类活动导致的栖息地破碎化以及广泛存在对随海拔分布森林带的破坏，可能会伴随因季节变暖的云层上升而加剧，不可能不妨碍有效的区域转移，这对于依靠森林生活而迁徙范围有限的种群而言尤其是这样。

Simulation results verify that insulated board can effectively protect the heat from transferring into the foundations, and the frozen table is always around the lower bottom of the boards; the position of the frozen table with insulated boards is higher than that of without; the embank- ment formation has a better effect on the center of embankment, the shoulder and toe of the roads than others; after consideration of the construction effect, the best lay out of the insulated boards is higher than the position of natural ground surface to 0.3-0.6 m; this formation of the embankments is the right effective constructer to be used in the permafrost on the Qinghai-Tibet railway.

通过数值模拟可知：保温板能够有效地阻止热量由路基面向下传入地基中，使0℃等温线始终在保温板底层；复合路基多年冻土上限的位置要比无保温板时的高；该结构形式对路基中心、路肩和坡脚下的多年冻土上限抬升的综合效果更好；考虑施工条件后，复合路基在保温板铺设距离天然地面之上0.3~0.6 m对于路基稳定性最为有利；该路基结构形式为青藏铁路多年冻土区路基的理想结构形式，有利于克服全球变暖的影响。

As a developing country, there still have 30 years to stop the production and distribution of R 22 in China , and there are very few technical obstacles in substituting C22 for R 410A . But the substitution will follow with the higher costs of production. And because of the threat of 揼 lobal warming? the future of R 410A is still unclear. How can the air-conditioner industry deal with this problem?

作为发展中国家，中国距最终禁止 R22 的生产与销售还有 30 余年，虽然目前进行绿色制冷剂的替代在技术上的障碍并不多，但随之而来的却是空调生产成本的提高，而且面对着全球变暖的问题， R 410A 等绿色制冷剂的前景还并不明朗，那么在这个问题上，空调行业将走向何方？

But the phenomenon that the American newspaper job that current economic depression creates queues up to close down, john Nicholas of famous reporter of free manner and air and Robert Maikeqiesini point out, its are urgent degree no less than " terroristic, pestilential, finance breaks down and climate browbeats calefaciently ", of newspaper close down to bring about what the society controls function to be short of likely break.

但目前的经济衰退造成的美国报业排队倒闭的现象，著名的自由派记者约翰·尼古拉斯和罗伯特·麦克切斯尼指出，其紧急程度不亚于&恐怖主义、瘟疫、金融崩溃和气候变暖的威胁&，报纸的倒闭有可能导致社会监督职能的缺失。

Breath, muscle contraction of the buttocks; arch body, as far as possible to hold his head, right leg straight towards the ceiling (peg-leg knee in order to avoid muscle tension).

呼气，收缩臀部肌肉；拱起身体，尽量抬起头来，右腿伸直朝向天花板（膝微屈，以避免肌肉紧张）。

The cost of moving grain food products was unchanged from May, but year over year are up 8%.

粮食产品的运输费用与5月份相比没有变化，但却比去年同期高8％。
