坑

A video camera was inserted into the unexcavated pit.

他们在未挖掘的坑里安装了录像机。

Expect for a few pittings,the N+1-implanted surface had a best fineness (average roughness Ra≈4.2nm), close to the unimplanted original surface.The N+2-implanted surface had a black dendritic area,and had a poorer fineness (Ra≈16nm).While in the N+10-implanted surface appeared a ripple structure,with the poorest fineness (Ra≈40nm).

但其表面形貌各异：N+1注入的表面除存在少量点蚀坑外，光洁度最高(平均粗糙度Ra≈4.2nm)，接近未注入前的原始表面(Ra≈3.5nm)；N+2注入的出现黑色枝状区域，光洁度次之(Ra≈16nm)，而N+10注入的则出现&波纹&状结构，光洁度最差(Ra≈40nm)。

The comparative experiments on the abrasion under unlubricated friction condition between the samples with smooth and coupling nonsmooth surfaces were performed by help of the experimental optimum design.

采用试验优化设计方法对相同试验条件下凹坑形仿生光滑试样以及具有仿生耦合表面的非光滑试样进行了干摩擦磨损试验对比研究。

Yet vast areas of the Pacific are unmapped and the Indian Ocean has hardly been touched. We know that several depressions in the floor are deeper than Mt.

我们已经知道有几个海床坑处的深度高于珠穆朗玛峰的高度，但是我们不能确定我们已经找到了海底最深的地方。

But he could not wait. He unstrapped the tin bucket and began to bale the pool.

可是他等不及了，解下铁罐，开始往坑外舀水。

Rescuers found the puppies living in an unventilated 10-foot pit with stagnant water, feces, maggots and animal carcasses.

救援人员发现，小狗在不通风的10个生活尺的积水，粪便，动物尸体和蛆坑。

So, perhaps, shall break upon us that eternal morning, when crag and chasm shall be no more, neither hill and valley, nor great unvintaged ocean; but all things shall arise, and shine in the light of the Father's countenance, because itself is risen.

也许，在这里，这是一个恒久的早晨。在这里不需要更多的峭壁，深坑，裂口，不要山川山谷，也不要古老的大洋，但是每样东西却都必须升起来。在自然父亲的关怀下升起来，没有什么原因，因为升起来本生就是原因。它是一种使命。

As the Pau'ans developed on the surface, the sinkholes have long been home to the Utai.

帕族是从行星表面发展出来的，而这些灰岩坑长期以来一直是尤塔人的住所。

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。
