凹地

The vane is a technique for river bank protection,which can alter direction of velocity and eliminate observably the centrifugally induced secondary current to reduce concaved bank scour and protrude bank sediment in river curves.

导流板是一种保护冲刷河道河床的技术。它能够改变水流的流向并能显著地减少弯道水流中的次生水流，从而解决了弯道中凹岸冲刷，凸岸淤积的问题。

And the concepts of dualistic contrariety could be seen in everything of the whole world, for example: life is opposite to death, sky is opposite to land, concave is opposite to convex and so on.

But a great of such paper were vertical hung like this and that and the taste and quality of each paper were polymerized and stacked again and again with massive texture, large cubic, narrow distance and iterative layer made me an intuition of dispirit and indistinction, caused by that I got the title from the works of Jia Pingwa.

可许多张这样的纸如此这般地直立悬置在一起，每一张纸的质味在重复中叠加与聚合，粗砾的肌理、硕大的体量、逼仄的距离、往复的层次，让我生出颓败与困顿的直觉，这才借得贾平凹先生的书名来用。

For added flexibility, one end of the SH1294M's cabinet is fitted with a recessed well, or socket, which allows the system to be easily pole mounted on a speaker stand for FOH or cross-stage monitor applications.

为了增加灵活性，其中一个SH1294M内阁结束配有凹入良好，或插座，这使得系统可以方便地在一个杆位用于FOH或跨扬声器独立安装阶段的监控应用。

Those persons who wish to gain a clear idea of the battle of Waterloo have only to place, mentally, on the ground, a capital A. The left limb of the A is the road to Nivelles, the right limb is the road to Genappe, the tie of the A is the hollow road to Ohain from Braine-l'Alleud.

希望清楚地了解滑铁卢战争的人，只须在想象中把一个大写的A字写在地上。A字的左边一划是尼维尔公路，右边一划是热纳普公路，A字中间的横线是从奥安到布兰拉勒的一条凹路。A字的顶是圣约翰山，威灵顿所在的地方；左下端是乌古蒙，雷耶和热罗姆·波拿巴①所在的地方；右下端是佳盟，拿破仑所在的地方。

It is a wheel with a grooved rim and can rotate freely.

它是一个带有凹边的齿轮而且能自由地转动。

The heat transfer plates in the assemblies have spaced apart dimples for maintaining plate spacing and oblique undulations with the undulations on adjacent plates preferably extending at opposite oblique angles.

在组件(40)中的传热板(44，48)具有用以保持板的间距的相分隔开的凹坑(54，56)，该传热板还具有斜向的波纹，在相邻板上的波纹(52)优选地按相反的斜角延伸。

Large hands fitting providentially into a deep dent in the side of the van's body.

那双大手如有神助地嵌在了货车车身一侧的一道深深的凹痕上。

Because of the sampling processing, we can take the simple concave domain analysis and ICM optimization in two different levels, so as to make both the parameter estimation and optimization much easier to implement, while delivering a satisfactory result; The third one is based on the multi-resolution analysis, robust statistics and majority game theory. 4. Propose a new clustering algorithm based on the entropy concept, which is used for unsupervised segmentation of color images.

重点讨论非监督的图象分割问题，并给出了三种新方法：一是基于贝叶斯学习和全局竞争策略的方法，把参数估计和图象分割有机地结合在一起；二是基于分层的框架，从抽样定理出发，在两个不同的层次上使用简单的凹域分析和ICM优化，可以使得参数估计和优化问题都变得简单易行，并得到满意的结果；三是基于多级分析、鲁棒统计的参数估计和多数博弈论的优化算法。

As she looked at Warrington's manly face, and dark, melancholy eyes, she had settled in her mind that he must have been the victim of an unhappy attachment.

每逢看到沃林顿那刚毅的脸，那乌黑、忧郁的眼睛，她便会相信，他一定作过不幸的爱情的受害者。
