变暖

"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。

All the world's major climatological and scientific organisations now concur on the risk of global warming, although the rate at which it will occur is disputed.

目前全球主要气象和科研机构都承认全球变暖的危害，但对其发生的速度仍存在争议。

Yes, it is a paradox, but global warming can trigger a colling trend.

是的，它是一种自相矛盾，但全球气温变暖会导致循环的趋势。

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的破碎化以及广泛存在对高地森林带的干扰，将伴随因季节变暖而上升的云层而加剧，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能力有限的物种而言尤其是这样。

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。

人类聚居地的膨胀和对森林走廊日趋严重的大规模的破坏(这可能随着气候变暖而致使云层升高)势必阻碍区域迁移，尤其是依赖森林生存的，自身带有潜在迁徙限制的动物种类。

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。

Study shows that environment evolution and eustatic change of Holocene in this area may be divided into 6 stages:① early stage of early Holocene, 9 100~10 900 aBP,when sea level was low and this area was an oxidizing environment or oxidizing-reducing transition environment;② late stage of early Holocene, 8 000~9 100 aBP, sea-level rising,...

研究表明，本区全新世环境演化分为6个阶段：①早全新世早期，10900~9100aBP，海平面较低，尚未淹没本区，为近岸氧化环境或氧化—还原过渡环境；②早全新世晚期，9100~8000aBP，海水上涨，本区时淹时退，为浅海或潮坪环境，生物钻孔发育；③中全新世主体，8000~4150aBP，海平面快速上升，完全淹没，Fe2+/Fe3+介于0.7395~1.9123之间，为全新世中最高段，表明还原程度强、全球气候变暖；④中全新世后期，4150~2850aBP，海水有所下降，仍为浅海环境，Fe2+/Fe3+较高，多在1.0以上；⑤晚全新世，2850~1310aBP，海平面进一步下降，本区时常暴露，其中2150~1310aBP以还原环境为主，为潮下带，2150~2850aBP以氧化—还原过渡环境为主，为潮间带；⑥1855AD以来，海平面基本稳定，稍有上升，为现代黄河三角洲沉积时期。本区全新世至少存在5期冷热交替的旋回性气候变化。

The latest was a panel from the National Academy of Sciences,enlis ted by the White House,to tell us that the Earth s atmosphere is de finitely warming and that the problem is largely man made.

最近的行动是由白宫召集了一批来自国家科学院的专家，这些专家告诉我们地球气候确实在变暖，而这个问题主要是人为造成的。

As global climate getting warmer,the acceleration of ice cap melting in Arctic region makes the geostrategic position of the region much more noticeable. The geopolitical rivalry for the Arctic region has heated up.

随着全球气候变暖，北极地区冰盖的加速融化使得北极地区的地缘战略地位凸显，对北极的争夺逐渐成为地缘政治竞争中一个比较突出的现象。

However, as the name（read－only memory）implies, CD disks cannot be written onorchanged in any way.

然而，正如其名字所指出的那样，CD盘不能写，也不能用任何方式改变其内容。

Galvanizes steel pallet is mainly export which suits standard packing of European Union, the North America. galvanizes steel pallet is suitable to heavy rack. Pallet surface can design plate type, corrugated and the gap form, satisfies the different requirements.
