粗糙表面

Carry on structure analysis to the spare parts first, understand its structure characteristics to choose suitable semi-finished product and the semi-finished product manufacturing of the reasonable a craft thus;Then the technique request of spare parts carries on analysis, understanding it each process superficial accuracy grade and the surface rough degree, make it process the fixed position in the process and clip a tight way in assurance inside the scope of economic accuracy, draw up the machine of spare parts to process craft process thus and further, choose each work preface to process equipments and craft material, the assurance slices to pare dosage and craft size, computing the man-hour of each work preface settle sum.

首先对零件进行结构分析，了解其结构特点从而选择合适的毛坯以及合理的毛坯制造工艺；再零件的技术要求进行分析，了解其各加工表面的精度等级以及表面粗糙度，使其在经济精度的范围内确定加工过程中的定位和夹紧方式，从而进一步拟订零件的机械加工工艺过程，选择各工序加工设备以及工艺装备，确定切削用量以及工艺尺寸，计算各工序的工时定额。

It is shown that a "labyrinthic" structure with mass cuboid plateaus and caves is formed on the surface of aluminous sheet.

研究结果表明，表面微细粗糙结构对表面的超疏水性起到了决定性作用，是制备超疏水表面的关键所在。

Because the positron annihilation spectroscopy can directly show the information of the defects in the materials, we have measured the positron life of the gallium arsenide samples of different surface roughness. And we have discussed the effect of the surface topography on the positron life.

因为正电子湮没谱测量能直接给出缺陷的信息，我们用正电子寿命谱测量不同表面粗糙度的GaAs样品，讨论了表面形貌对常规正电子寿命测量结果的影响。

Such as angle grinder, wire brush, needle beam pneumatic rust, and wind knock rust hammers, gear-type rotary rust, etc., are semi-mechanized equipment, tools, light, mobility, and to more thoroughly to rust , old coatings, the coating can be played on the shelf hair treatment, significantly more efficient than manual derusting increased up to 1 ~ 2m2 / h, but can not remove the oxide skin, the smaller surface roughness and can not achieve high-quality surface to deal with quality, ergonomic handle lower than the jet.

如角向磨光机、钢丝刷、风动针束除锈器、风动敲锈锤、齿型旋转除锈器等，属于半机械化设备，工具轻巧、机动性大，能较彻底去除锈、旧涂层等，能对货架涂层进行打毛处理，效率比手工除锈大大提高，可达1~2m2/h，但不能除去氧化皮，表面粗糙度较小，不能达到优质的表面处理质量，工效较喷射处理低。

Carborundum, emery abrasive carborundum powder is applied to two kinds of dry and wet production process of the most affordable of the abrasive, especially for the more rough treatment of the workpiece surface, while the treated surface, also requested a more elaborate occasions.

金刚砂，金刚砂磨料，金刚砂微粉是一种适用于干式和湿式两种生产工艺的最经济实惠的磨料，尤其适用于对较粗糙的工件表面进行处理，而处理后表面又要求较精细的场合。

These components require not only high precision and low surface coarseness, but also no hypo-surface damage.

这类元器件不仅需要极高的精度和极低的表面粗糙度，还要求无次表面损伤。

Experiments were performed with this device to measure the static coefficient of friction for three kinds of material(45steel,HT35-61,QT80-2) in the same processing method,the same surface texture,the same load,dry friction and different surface roughness conditions respectively.

分别对材料(45钢、HT35-61、QT80-2)在相同加工方法、相同表面纹理、载荷恒定、干摩擦条件下，改变表面粗糙度时的静摩擦因数进行了测定。

studies the result shows the bacterium is right originally the conglutinate ability of surface of artificial and articulatory material not only depend on bacterial itself, also concern with material property and exterior surface roughness.

结论本探究结果表明细菌对人工关节材料表面的粘附能力不但取决于细菌本身，也和材料性质和表面粗糙度有关。
