The applicability of the model will be high for Continental Airlines in Newark, New York, Logan Airport and Washington air shuttle between the airport, after the route has been carried by the jet.

这款适用性高的机型将被用于大陆航空纽约纽瓦克机场和华盛顿洛根机场之间的穿梭航空，此前该航线一直由喷气飞机执行。

Alaska" may be derived from an Aleut, which means "the mainland.

阿拉斯加"一名可能来源于Aleut，意思是"大陆。

Rock slides are a fact of life on mountainous roads, but the increase is due to the bow pulling the N American continent, pulling the Aleutian Islands toward the tip of Mexico.

岩石滑落现象是多山道路上的一种无法改变的事实，但滑落现象的增多是由于北美大陆弓形地带挪动，在将阿留申群岛往墨西哥顶部拉动。

One was the pressure the N American continent is under as it is pulled into a bow, the Aleutian Islands pulled toward the tip of Mexico, with the center of the bow at San Diego.

其中一个是由于北美大陆被拉成了弓形，板块底部受到压力，阿留申群岛被朝着墨西哥顶部的位置拉伸，而弓形的中心位置处于圣地亚哥。

Because of this, allied forces still stand on this continent.

由于这一原因，盟军仍然站在这个大陆。

During the postgenomics era the information about genomic sequence and gene functions provides a new foundation for evolutionary biology and ecology As the first whole-genome sequenced plant Arabidopsis thaliana and its wild relatives have played a critical role in understanding the evolution of genomics and speciation Both A halleri and A lyrata are closely related to the model species A thaliana A halleri ssp gemmifera occurs in northeastern China Japan and Taiwan; while its sister A halleri ssp halleri is mainly distributed in Europe Geographical barriers such as Tienshan Mountain Range isolate these intraspecific sisters Likewise A lyrata ssp kamchatica and ssp lyrata occur in East Asia and North America respectively Such distribution patterns seem to be consistent with allopartic speciation The comparison between ancestral and extant polymorphism by multilocus can be informative about the population genetics of speciation In this study we collected and analyzed DNA sequences of 98 genes from four wild relatives of A thaliana A halleri ssp gemmifera A halleri ssp halleri A lyrata ssp kamchatica and A lyrata ssp lyrata The ancestral states of these four species were compared to each other in terms of level of genetic variation However the ancestral species at the time of speciation were substantially more polymorphic than the extant geographical populations The observations are not fully compatible with speciation by strict allopatry At some species pairs parapatric speciation seems more reasonable in speciation of Arabidopsis The 98 gene sequences are also used for the congruence test between gene genealogy and species phylogeny Only 28 genes support the species phylogeny but there are 23 genes supports another major genealogy { lyrata} thaliana Based on the phylogenetic position change of A lyrata ssp kamchatica and Ks value for each species pair suggested the recent directional gene flow between A halleri ssp gemmifera and A lyrata ssp kamchatica

阿拉伯芥是第一个完成基因体定序的开花植物，其基因体资讯提供植物学研究的重要依据；在解析阿拉伯芥属物种的亲缘关系以及种化机制等重要的演化议题时，阿拉伯芥近缘的野生物种自然成了不可或缺的关键；跟阿拉伯芥近缘的物种包括A halleri及A lyrata，其中A halleri ssp gemmifera主要分布於中国东北、日本以及台湾，与近缘的A halleri ssp halleri其分布於欧洲隔著天山及大陆的障蔽，而A lyrata ssp kamchatica主要分布於东北亚及台湾，与分布於北美五大湖的A lyrata ssp lyrata被北极圈所分隔，这样的分布模式暗示异域种化的可能。藉由多基因分析比较祖先物种与现生物种遗传歧异度的相关可提供讯息探讨种化时期的族群遗传结构，本研究针对A halleri ssp gemmifera、A halleri ssp halleri及A lyrata ssp kamchatica、A lyrata ssp lyrata四个物种，两对互为亚种的姊妹群，以阿拉伯芥为外群进行研究，在四个物种完成98个同源基因的分子序列，利用套装软体MCMCcoal来估算祖先物种的遗传变异，亦估算现生物种的核苷酸歧异度，观察到？多物种配对中祖先物种遗传多型性大於现生物种DNA歧异度，显示异域种化模型并无法完全解释阿拉伯芥属物种的种化模式，在某些物种配对间邻域种化模式应比异域种化更为可能；在基因树与物种树的比较，98个基因片段的亲缘模式只有28个是与已知物种树一致的，有23个基因其树状图支持{ lyrata} thaliana的型式，藉由kamchatica位置的变化以及估算各物种配对间的平均同义置换率，推测在A halleri ssp gemmifera与A lyrata ssp kamchatica间具有近代的单方向基因交流。

There into the sea on the continental shelf of alluvial river delta formation.

在大陆架上有流入大海的江河冲积形成的三角洲。

There are significant differences among the aloes which have different breed and shape from others.

芦荟的品种至少有300种以上，其中非洲大陆就有250种左右，马达加斯加大约有40种，其余10种分布在阿拉伯等地。

The study of ocean color is an important part of the ocean research. The suspended matter is the major resource for the alongshore sediments and its distribution character and density have much relate to the flux balance of the sediments in the estuary.

海洋水色的研究是海洋研究的重要一部分，对于大陆边缘及近岸区域来说，陆源悬浮体是边缘海海底沉积物的主要来源；同时，其分布特征及数量变化与河口附近海域海底沉积物的通量平衡有很大的关系，因此，关于悬浮体的调查研究是十分必要的。

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。
