坑

He saw before his clouding eyes a black pit.

他看见在他混浊的眼睛一黑坑。

In a country with endemic dysentery and fevers and cold-water baths and a hole in the gound instead of a toilet.

在一个流行痢疾和热病，冷水浴，在地上挖一个坑就当茅坑的而不是卫生间的地方。

I will mark the place so you can see my compost pile more easily.

我会在堆肥坑做标记，让你更容易找到。

And provide some methods to avoid the ""small concavity"".

并结合叶片加工的特点提出了几种合理避免"切坑"现象的方法。

The results showed that a concavity in the surface could be clearly observed at the center of starches.

结果表明：微波淀粉颗粒表面出现凹坑，降低了膨胀度和溶解度、冻溶稳定性。

This paper is focused on the ""small concavity"".

本文正是针对这种"切坑"现象展开研究。

With this scheme, however, technologist found that there are a series of small concavity on the edge of the blade, and it can become the most reason that cause the reject, extremely.

然而在实际加工中，工艺人员发现使用这种方法加工出的叶片在缘头部位会出现连续的小坑，严重时还可导致零件报废。

The result of the industrial test of the prototype at the Mine's concentrator was satisfactory.

该机在铁坑铁矿选矿厂进行工业试验，已取得良好的结果。

In the fluvial deposit environment, the quartz superficial characteristic is primarily by the inferior circle, the conchoidal breakage fracture and the submarine hit pit, revealing the transformation of current to the quartz; In lake-deposit environment, quartz sand superficial characteristic is by primarily abraded edges and parallel cleavage, the quartz maintained the primitive characteristic, indicating the quartz received few transformation of fluent, different quartz grain has their different curve character.

在河流沉积环境，石英砂的表面特征以次圆、贝壳状断口和水下撞击坑为主，显示了水流对石英砂颗粒表面的改造；在湖泊沉积环境中，石英砂的表面特征以多棱角和平行解理面为主，石英砂颗粒保持了原始的特征，表明了石英砂颗粒受到水流的改造比较少。不同沉积环境中石英砂颗粒表面结构特征都具有自己的曲线特征。

Both the a-axis and ab-plane dip towards the downstream , the dip angles of the a-axis are low and concentrated, being 7—8°,the ab-plane dips at 7～21°, and the a-axis has more preferred dip of fabrics than the ab-plane; the peak of the grain-size frequency distribution curve of deposits in the Lushan area is in the range of 4 and 5 φ;The quartz sand grains are subangular and have well-developed conchoidal fractures, parallel striatio ns, upturned cleavage flakes,"V"-shaped holes and siliceous deposits.

摘 要：庐山第四纪泥砾沉积物的砾石组构特征表明，砾石岩性与山体基岩基本一致，砾石的等体积球径较小，加权平均砾径较中值砾径大，分选系数大于1，分选性差，φ值相对较小，平均为0.66，F值相对较大，在2左右，F/φ比值介于2.75～4.75，ρ值集中且较小，为22.75%～37.75%，砾石以棱角、次棱角状为主，磨圆较差；a轴和ab面都倾向沟谷下游，a轴倾角集中且较小，为7～8°，ab面倾角为7～21°，a轴较ab面具有更为优势的组构倾向；沉积物粒度频率曲线在4～5Φ范围内表现为峰；石英砂颗粒为次棱角状，贝壳状断口发育，具平行擦痕、上翻解理片、V形坑和硅质沉淀。

I didn't watch TV last night, because it .

昨晚我没有看电视，因为电视机坏了。

Since this year, in a lot of villages of Beijing, TV of elevator liquid crystal was removed.

今年以来，在北京的很多小区里，电梯液晶电视被撤了下来。
