In a transportation network supported by the Advanced Traveler Information Systems,the drivers equipped with ATIS are directed by a control center to select their routes so as to minimize the total network travel time,while the unequipped ones make the route choice decisions on the base of minimizing their individual travel times.

考虑一个被路径诱导系统支持的交通网络，装有ATIS的出行者接受交通中心的指挥、按照系统最优的原则选择路径，没有该装置的出行者根据个人成本最小的原则择路，建立了刻画这种混合交通行为的变分不等式模型，推导了混合交通行为网络的效率损失上界，并以多项式路段成本函数为例给出了一些上界的特殊值。

From the tests,we have obtained some structural variant features related with salt resistance and demonstrated the successful introduction of Rhizophora apicularta DNA into tomato.This thesis contains two parts. In the first part,the morphological and anatomical structures of the leaves were investigated. As to the morphology,some difference between control and transformed tomato were found. The leaf dimensions of the transformed tomato with unextended leaves were smaller than that of control. These structure changes should help to decrease the evaporation of water effectively and release the physiological drought resulted from saline.

本实验分两部分：第一部分、对转化番茄的形态及细胞显微结构进行观察与分析，实验表明转化番茄形态与对照相比有明显的变化，其叶面积变小，叶形收拢，这种结构可有效地减少水分的蒸发，缓解由盐胁产生的生理干旱；组织解剖结构结果显示，耐盐番茄在细胞结构上发生了明显的变异：其气孔器倾向下陷，表皮毛增多，叶脉微管组织不发达，微管束周围出现增多的贮水细胞，叶缘及其它部位表面分化出大型的多细胞分泌型结构，这些结构与转化番茄后代较强的耐盐能力有关。

It is only because of the enormous unterstellar distance that so little material per unit of volume becomes so significant.

只是因为星际之间的非常大的距离，使得每分体积中很小的物质变得很可观。

With the increase of the code rate , the production distance between the constellation of the unitary group code decreases rapidly and deteriorates the performance of the system.

Richer, well-educated families share their poorer neighbours' preference for sons and, because they tend to have smaller families, come under greater pressure to produce a son and heir if their first child is an unlooked-for daughter**.

富足、有教养的家庭和穷点儿的家庭一样偏爱男孩，因为他们的家庭规模变小了，如果第一个孩子是"讨人嫌"的女儿，那么他们会想再生个儿子将来以继承家庭财产，这样一来，他们会面临更大的压力**。

He not only inherits Xie Lingyun and Xie Tiao"s composed experience of the landscape poems, but also produces the obvious new change of his poem"s art: First, the transformation of landscape aesthetic ideal; second, the abundant connotation of landscape theme; Third, the movement of find-a-view image and sketchy pattern; Fourth, the poesy form of unpretending aloof.

他不仅继承了大、小谢山水诗的创作经验，而且其山水诗艺术发生了明显的新变：山水审美意识的转型；山水题材内涵的丰富；取景意象和写景范式的变化；质朴疏野的诗歌形式。

I always seemed to lose connectivity just when I was about to send a crucial e-mail--it's embarrassing to run down a city street waving your laptop around like a crazy person, but it's amazing how unselfconscious you get when you have to find one lousy bar of wi-fi in the next two minutes or you're going to get fired. A website called ThinkGeek.com sells a T shirt with a battery-powered wi-fi detector that displays the ambient signal strength wherever you happen to be standing.

气人的是，貌似网络总是在我要发一封重要邮件的时候断掉--在马路上跑来跑去，像个疯子一样"挥舞"着你的笔记本到处找信号的行为实在是让人尴尬；然而，在你为了不被炒鱿鱼而必须在两分钟之内找到一个提供Wi-fi的小酒吧的时候，你是会变得不顾一切的（ThinkGeek.com这个网站出售一款带Wi-fi探测器的T恤，电池驱动的探测器能让显示你所处位置上的Wi-fi信号强度。

And so time went on, and the little Rabbit was very happy so happy that he never noticed how his beautiful velveteen fur was getting shabbier and shabbier, and his tail becoming unsewn, and all the pink rubbed off his nose where the Boy had kissed him.

One reporter asked Upton specifically if there would be no further episodes in which he appeared to not hustle.

一个记者特别问Upton，有没有可能他说这些最终会变得雷声大雨点小。

The diameter of the rockbolt also has an effect on the mechanical properties. The larger is the diameter, the larger is the increasing of the moduli of the rock mass, but variation of the equivalent elastic constants are little.

锚杆直径增大而其他参数保持不变时，岩体锚杆支护系统复合材料的力学性质弹性模量随着直径的增大而有所提高，但等效强度常数变化幅度较小。
