坑

And some are caused because the grinding stone the grain grade is not reasonable or not polished so well.

肉眼看来光洁如镜的花岗石石材的表面，在反光显微镜下和扫描电子显微镜下可以看出石材表面都存在在磨抛加工后所留下的凹坑和条痕，这些凹坑和条痕有的是在目前的加工条件下无法克服的由矿物本身的缺陷而造成的，有的则是因为在加工过程中由于磨石粗细等级不合理或磨抛不彻底所造成的。

Welding completed, should be removed arc OFC boards and grinding formation, while the hammer down; Slag : After removal of the entire weld slag, welders self including weld appearance and size, etc.

焊条应与垂直面形成60°～80°角，使电弧略向上，吹向熔池中心；收弧：当焊到末尾，采用排弧法将弧坑填满，把电弧移至熔池中央停弧。严禁使弧坑甩在一边。

Also provided is an apparatus for conveniently raising and lowering the junction box in and out of a below ground cavity.

还提供一种装置，用于方便地从地下的坑中升起所述接线盒和向所述地下的坑中下降所述接线盒。

Trenches-- Trenches can also act as sumps or diversion pits that can aid soil in absorbing rain and runoff.

战壕-战壕也可以作为污水坑坑或转移，以助吸收雨水径流的土壤。

Theoretical analysis reveals that the formation of flower-like splats results from the interaction of surface tension, inhomogeneity of thermal contact resistance between flattening drop and substrate and substrate crater. The formation of the craters on the substrate is mainly controlled by substrate melting.

理论分析表明，&花瓣状&层片的形成是熔体表面张力、熔体与基底接触热阻的不均匀性和基底凹坑相互作用的结果；基底凹坑的形成主要由基底熔化所控制。

In order to study local scouring field near the pier with sediment control dam ,the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek.

采用Sontek公司声学多普勒测速仪对有拦沙坝防护的模型桥墩附近流场进行了精细测量，对桥墩冲刷坑内三维流速分布进行了分析，给出了冲刷坑内三维紊动特征量的分布，分析研究了有拦沙防护坝时桥墩局部冲刷的三个新特点，提出了拦沙坝的适用条件。

In order to study local scouring field near the pier with sediment control dam, the 3-D velocity field of the pier in monomer model is subtly measured by ADV velocimeter of Sontek. This paper analyses the velocity distribution in the scouring pool of pier and takes turbulent strength distribution in different direction. Three new characters for the local scours of piers with the sediment control dam are analyzed and the dam's applicability is brought forward.

Luxi County, Southòsuccess of quartz flour mill located in the western region of Pingxiang City, JiangxiòSouth Sakata village from Pingxiang city 15KM, convenient transportation.

芦溪县南坑镇成功石英粉厂位于江西西部的萍乡市南坑镇阪田村内，距萍乡市区15KM，交通便利。

After measurement and analysis of the interfering voltage, potential gradient, the point current density, the weight-loss increases with average current density, and the depth of penetration increases with the interfering voltage.

测量和分析了干扰电压、电位梯度、点电流密度、失重量及腐蚀坑深后，可以看出失重量随平均电流密度而增加，腐蚀坑深随干扰电压而加剧。

The test result has been described and the causes of differential subsidence on the bottom of test pit have been analyzed from two aspects (deformation of loess collapse and slip and subside of wet soil mass along fracture). On this basis, the article summarized that Surface water and ground fracture in the activities is to promote mutual interaction.

通过对试验的几种不同沉降关系曲线和试坑沉降变形等值线图的描述，文章从可能引起试坑产生不均匀沉降变形的两个方面(黄土湿陷变形、浸湿土体沿裂缝滑移下陷)作了探讨，得出地表水与地裂缝的活动是相互促进相互影响的关系。

Neither the killing of Mr Zarqawi nor any breakthrough on the political front will stop the insurgency and the fratricidal murders in their tracks.
