坑

Using scanning electron microscope we discovered that,compared to the diamonds from no-sulfur system,the diamonds from sulfur-contained system have hexoctahedron shape,but its surface has many small pit s.

借助于扫描电子显微镜，研究发现，与不含硫体系合成的金刚石相比，含硫体系合成的晶体虽然具备六八面体形状，但是表面有许多小的凹坑，这些凹坑多数分布在{111}面上。

Landslides in the local reporters saw the Hang Hang base base of the steel used to support the pillars of higgledy-piggledy.

站在塌方的地方记者看到，坑基内用来支撑坑基的钢管支柱横七竖八的。

The new data was collected by the NASA rover Opportunity in the Victoria impact crater, which is 750 meters across and 75 meters, in an equatorial region of the planet.

新的数据是由美国航天局漫游者"机遇号"在维多利亚冲击坑附近收集而来的，而该冲击坑跨度有750米左右，在火星赤道区附近也达75米左右。

It is approximately 22 kilometers (14 miles) in diameter, more than 20 times larger than another impact crater, Victoria, where Opportunity spent most of the past two years.

该坑直径约22公里，比"机遇"号过去两年大部分时间所呆的地方"维多利亚坑"大20倍。

On the basis of summarizing scientific goals of lunar exploration and analyzing distribution characteristics of landing sites, the authors chose three craters of Copernicus, Kepler, and Aristarchus in KREEP rock distribution area as candidate landing sites.

克里普岩对于研究月球的起源和演化有重要意义，但由于该岩石被玄武岩所覆盖，难以利用轨道探测器开展全面深入的研究。撞击坑是研究月表以下物质成分的窗口，在克里普岩区选择条件合适的撞击坑开展软着陆探测有助于对克里普岩的深入研究。

CD disk is an optical disc, on which data is recorded as a set of dips in the surface.

CD盘是一种光盘，其数据以一组坑的形式记录在光盘表面上，当激光束扫过这些坑的时候，返回的失真程度就代表了这些数据。

Therefore, the morphology of the etch pits can be predicted, or conversely the orientation of surface can readily be determined from the morphology of etch pits.

指出：利用这一点，在已知晶面的晶格对称性的情况下，可预料蚀坑的形状；或反过来，从蚀坑的形态可很容易判断其所在晶面的取向。

By field-testing methods, such as static cone penetration test, field vane shear test, and pore water piezometer test, the variation of strength and the pore water pressure are measured at real time, and the marine hydrodynamics' impaction on the consolidation process of the sediments in the Yellow River Estuary was studied. It is shown that the self-consolidated sediments have a very fast consolidation rate, under self-consolidation, in 72h, the consolidation degree reaches 37% and about 142h the pore water pressure disperse over, while under the hydrodynamics, in 72h the consolidation degree reaches 52% and about 195h the pore water pressure disperse over.

在黄河三角洲刁口叶瓣潮坪上，开挖2m×1m×1m的试坑，现场取土配置黄河口快速沉积形成的流体状堆积物，以铁板部分覆盖试坑隔绝波浪和潮流作用，利用微型贯入、静力触探、十字板剪切试验、孔隙水压力监测等原位测试手段，实时测定快速沉积的海床土强度发展以及孔隙水压力消散情况，研究快速沉积的粉质海床土分别在自重条件下以及在波浪和潮波等水动力作用下的固结过程。

All the other frogs gathered around the pit. When they saw how deep the pit was, they told the two frogs that they were as good as dead.

其余所有青蛙都围在坑的四周，他们一看坑那么深，就告诉那两只青蛙：他们死定了。

When Reuben returned to the pit and saw that Joseph was not in the pit, he tore his clothes

流便回到坑边，见约瑟不在坑里，就撕裂衣服

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。

Maybe they'll disappear into a pothole.

也许他们将在壶穴里消失
