坑

If it's not, you can end up careening off the road and into one deep ditch.

如果不是，你可以下场刮离路面，成为一个深坑。

One day, Paul Ince is being chauffeured home in Cheshire, when his driver swerves to avoid a pot hole and hits a strange looking beast on the side of the road, killing it instantly.

这天，因斯让司机带着去柴郡。当司机因为路上有坑而转弯的时候，撞到了路边一个很奇怪的野兽，它立刻死了。

Heat sintered ZrO_2 ceramic does not react with any acids and bases except HF. It can't be coarsened by the traditional pretreatment process. Through a great deal of experiments, author found a kind of coarsened prescription which can corrode ZrO_2 ceramic, forming many holes and troughs on its surface.

高温烧结后的ZrO_2陶瓷的化学稳定性很高，除HF外不溶于任何酸碱，传统的粗化液对它没有粗化作用，笔者通过大量的实验，找到了ZrO_2陶瓷粗化液的配方，它能在ZrO_2表面腐蚀出大量均匀的微坑和凹槽。

And for the uneven surface which is concaved into the surface, the defected concrete should be removed by chisels to form the pits and grooves that are deep enough for backfilling and repairing .

凹入表面以下的不平整表面用凿子除掉缺陷的混凝土，形成供填充和修补用的足够深的坑、槽。

There are many heaves and concaves which can be observed on the surface of the layer, and so they make the surface of the layer rough. The surface of the layer is rich in Ti, but gradually the Ti decreases. It shows that The combine of the layer with the base is good, which result from the heat diffusing and chemical metallurgy reaction.

涂层表面由许多凸起和凹坑组成，表面稍粗糙，这是脉冲放电的工艺特点决定；涂层内部Ti元素由表层至与基体界面处呈梯度分布，并且Ti元素也渗入基体一定深度，说明结合良好，为冶金反应和热扩散的结果。

Functional glasses are mainly hard and brittle, and are difficult to machine because cracks and concavities are easily form on the machined surface.

针对功能玻璃硬度高、脆性大、容易在已加工表面产生裂纹和凹坑的特性，提出基于大刃倾角刀具的玻璃切削加工方法。

In order to solve this problem, a glass-cutting process by using a single- straight tool with big inclination angle is proposed, which helps to obtain integral surface without cracks and concavities in a culling depth at sub-millimeter level.

该方法能在亚毫米级的切削深度下高效地获得无裂纹和凹坑的完整表面。

However, many of them are not only hard but also brittle and are difficult to be machined by a cutting tool due that cracks and concavities form easily on machined surface.

但功能玻璃大都硬度高、脆性大，易在已加工表面产生裂纹和凹坑。

Precise cutting of glass using single-straight tool with big inclination angle is a new machining method in which integral surface with no cracks and concavities can be machined out high efficiently at the cutting depth of sub-millimeter level.

基于大刃倾角刀具的玻璃切削是一种新的加工方法，该方法能在亚毫米级的切削深度下高效地获得无裂纹和凹坑的完整表面。

Some cord to a surface hardness low Corrugating roll also therefore create top cord to boundaries Ma Hang and depression and wear process.

一些楞面硬度低的瓦楞辊还会因此使楞顶楞面产生麻坑和凹陷，加剧了磨损进程。

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。
