坑

Based on the former drag reduction experiments of the bionic nonsmooth body of revolution models in the lowspeed wind tunnel, the simulation wind tunnel tests at the wind speed of 44 m/s were performed for the body of revolution models with the tail rectangularly disposed by three different nonsmooth structures, such as the convex dome form with the diameter/height of 1.0/0.5 mm, the dimple concave form with the diameter/depth of 1.0/0.5 mm, and the riblet form with the width/height of 1.0/0.5 mm, in contrast with the body of revolution model with smooth surface.

在前期进行的仿生非光滑旋成体模型低速风洞试验的基础上，将非光滑形态在旋成体模型上的排列方式固定为矩形布置，非光滑的尺寸固定为直径或宽度为1 mm，深度或高度为0.5 mm，在风速为44 m/s时，对布置在模型尾部的凸包形、凹坑形和棱纹形三种非光滑模型与表面光滑模型进行了对比模拟试验。

Regular concave surface profiles are adopted for many friction surfaces, but the surfaces are seldom studied using lubrication theory.

摘 要：规则凹坑表面形貌在许多摩擦副中被采用，但目前为止仍缺乏理论指导。

In addition, the removal of the trees and then move back to rehouse some difficulty, to move back to a tree pit to be dug appropriate, but the new roads the following pipelines are often more, dig deep and pit may cause damage pipelines.

另外，移走的大树再回迁安置有一定难度，回迁大树要挖相应的大坑，但新修道路下面往往管线较多，挖深坑和大坑可能会对管线造成破坏。

I don't wanna get ripped off.

我可不想被坑了。

The pump have many traits eg: small volume、light weight、manipulate simple and convenient、moving agility 、work placidity and credibility、 high efficiency、 saving energy sources , safety and so on.Especially in narrowness roomage's sap ostium、 grub entrance、low coal seam region and so on,it is also the bigness pumping station cannot instead.

I want to assure you that I think there is absolutely nothing wrong with the name Roscoe if you never want your child to be anymore than a truck mechanic or run a roadside barbecue pit in Kentucky.

我想向大家保证，我认为是绝对没有错的名称罗斯科如果您不希望您的儿童须再比一卡车的机械或运行的路边烧烤坑在肯塔基州。

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。
