原因明显的

The habitat condition was more diversifiable and complicate.

河口上游区域的大面积围垦造地及环境污染是降低底栖动物食性功能群多样性的主要原因，缺乏杂食和碎屑食者，且肉食者物种很少，说明了区域生境破碎化明显，导致营养源的减少以及食物链的简单化。

Different climate change in west and east part of north China in recent years is major reason for this phenomenon, not vegetation cover, but degenerated vegetation cover, corresponding to abnormal droughty climate during these period, is one of reasons for abnormally high dust activity in the end of 9Os'in Huabei Plain.

九十年代末，对应于我国北方地区，特别是华北地区干旱少雨的气候条件，植被覆盖状况有明显下降的趋势，这可能是世纪末华北地区沙尘活动频繁的一个重要原因，但我国西部沙尘源区沙尘气溶胶光学厚度仍然保持继续下降的趋势。

The reason is that eidently, progress in classified or 'secret' technology has pulled far ahead of what is known to the aerage college physics professor.

原因很明显，机密或者&隐蔽&的技术的进步远远领先于大学物理学教授所知的常识。

But the reason is clear -- those to whom Paul wrote his great and later Epistles had not the eschatological difficulties of the Thessalonians to meet.

但是，原因很明显-那些人保罗写道：他的伟大，后来书信没有困难的末世论的撒罗满足。

The Green River site is important because it reveals information about the climate during the Eocene and the transitions during the period itself, including the significant faunal change that occurred in North America.

绿河所在地很重要的原因就是他揭示了始新世的温度和转变情况，包括在北美的明显动物系的转变。

They are spatially res tricted by geosynclinal structural layer and are temporally controlled by Diwa stage.

本区金矿空间上受地槽构造层的制约，而成矿时代则受地洼阶段的限制，这就是本区金的成矿时代明显不同于世界其它地区的原因。

This is a group whose members no longer care about programming as their primary function, but instead work together — writing, performing, and jamming — as a band. The 14 guests here range from Celtic fiddle wizard Eileen Ivers to griot and kora master N'Faly Kouyate.

先是以一个崭新的面孔开一派之先河，然后电声味越来越浓，音乐也相对显得浮躁，尽管其中不乏与 Sinead O'Connor 合作的优秀作品如《Release》等曲目，但这很明显是他们连续三张专辑获得的评价都不高的最大原因。

Suction was applied, drawing the Dieulafoy lesion and the surrounding mucosa into the lumen of the ligator,~preloaded elastic band was fired, and the Dieulafoy lesion was ligated by the elastic band.

Dieulafoy病变是引起上消化道大出血的原因之一，近年来随着内镜诊断水平的不断提高，其发病率有明显上升的趋势。

Results:The reasons of unresectable 131 lung cancer were: metastasis in the thoracic cavity, freezing of hilum of lung, neoplasma encroach the main organs of mediastinum, and could not tolerate the extended resection because of the limitation of pulmonary function.

结果：131例肺癌不能切除的原因依次为：胸腔内多发转移，&肺门冻结&经打开心包仍不能处理血管，肿瘤侵犯纵隔内重要结构，以及肺功能受限不能耐受扩大切除范围等。1992年~2006年的探查率为8.1%(66/813)，较1985~1991年的15.6%(65/417)有明显下降。

孟庆伟等（1996）认为光呼吸可减轻光抑制，尤其在发生光合午休时更明显，而对光合作用却有反作用，Zelitch (1992)的研究表明光呼吸随温度的升高而升高，因此高蛋白小麦中午较强的光呼吸作用可能是其Fv/Fm下降较少，而净光合速率下降幅度较大的一个重要原因。

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。
