Conductor surface roughness in printed-circuit boards(PCBs) is a material parameter that should not be overlooked.
印刷电路板（PCBs）导体的表面粗糙度是一个不能忽视的材料参数。Similarly, the surface roughness of metal stamping parts should also be properly regulated according to the actual needs of the mating surface. .
同样，金属冲压件的表面粗糙度应根据匹配表面的实际需要适当规定。Usually cold extrusion parts surface roughness Ra of at least 0.63~ 1.25μm or more.
一般冷挤压制件的表面粗糙度值Ra至少在0.63～1.25μm以上。Similarly, the surface roughness of metal stamping parts should also be properly regulated according to the actual needs of the mating surface. .
同理，零件的表面粗糙度也应当根据配合表面的实际需要，作出适当的规定。The surface roughness(to ISO 4288 or DIN 4768) of the housing bore should be kept within the limits specified in the table.
座孔的表面粗糙度（符合ISO4288或DIN4768）不应超出表中所列的极限。There was some surface roughness at this point, so flap and polishing wheels were again used to improve the surface. .
在这个阶段会产生一定程度的表面粗糙，所以再次使用抛光轮来对表面进行抛光。The piston should make smooth reciprocating sliding in the cylinder, and the surface roughness of the inner surface of the cylinder should reach Ra0.8um.
活塞要在缸筒内做平稳的往复滑动，缸筒内表面的表面粗糙度应达到Ra0.8um。High-speed steel tools can be sharpened sharply, but with a short hold time, so the surface roughness is small at low speed cutting.
高速钢刀具能刃磨得很锋利，但保持的时间较短，所以在低速切削时表面粗糙度值较小。When cutting plastic metal, when the cutting speed is very low or high, the surface roughness value is small.
切削塑性金属时，当切削速度很低或很高时，表面粗糙度值较小。Can make the size tolerance grade"MT" to 12-14, the surface roughness increased to 25-50 microns.
可使尺寸公差等级“MT”提高到12-14级、表面粗糙度提高到25-50μm。Grinding surface roughness is closely related to the accuracy of the part, and certain accuracy should have a corresponding surface roughness.
磨削表面粗糙度与零件精度有密切关系，一定的精度应有相应的表面粗糙度。The aim of the project is to obtain soil and vegetation parameters using a cloud-water model describing surface roughness and soil moisture.
项目旨在通过利用水云模型获取土壤和植被的参数，以描述地质表面粗糙程度和土壤湿度。One theory argued that the greening of the Earth or more urbanisation was increasing surface roughness and curbing wind speeds.
有一种理论认为，地球绿化或城市化加剧正在增强地表的粗糙度，并限制了风速。A space-based observatory would detect and carry out remote sensing and the physical characterization of NEOs: their size, composition, surface roughness, and so forth;
将由一个空间观测站进行探测和遥感，并测定近地物体的物理特征：体积、构成、表面粗糙度等等；.(2) or process refers to the direct change in raw material semi-finished size, shape, surface position, surface roughness or performance, making the finished product process.
(2)工艺过程指直接改变原材料半成品的尺寸、形状、表面的相互位置、表面粗糙度或性能，使之成为成品的过程。Found that good adhesion between the coating and the body material, low surface roughness and small cutting edge radius can achieve good cutting results.
Endler等研究发现：涂层与刀体材料之间良好的结合力、低的表面粗糙度以及小的切削刃半径可以得到很好的切削效果。(2) the dimension precision of die casting is high, which can reach IT11- 13, sometimes up to IT9, the surface roughness is Ra0.8- 3.2um.
压铸件的尺寸精度较高，可达IT11-13级，有时可达IT9级，表面粗糙度达Ra0.8-3.2um，互换性好。The mould casting surface is then 5 axis milled removing approximately 5mm of wax to create a high quality mould(approximately 20 micron surface roughness).
然后将模具铸造表面进行5轴铣削，去除约5mm的蜡，以产生高质量的模具（约20微米的表面粗糙度）。Electrochemical polishing process is divided into two steps:(1) macroscopic leveling dissolution products to the electrolyte diffusion, the material surface roughness decreased, Ra> 1μm.
电化学抛光过程分为两个步骤：（1）溶解产物的宏观流平扩散到电解质中，并且材料的表面粗糙度降低，Ra>1μm。Clearance and re-grading of the berms will cause disruption of soil and vegetation, so gravel should be applied to the disturbed areas to stabilize the soil surface and increase surface roughness.
清除和平整围墙将破坏土壤和植被，因此应在受影响地区覆盖碎石，以稳定土壤表面并加大表面粗糙程度。
