Printed boards and printed board assemblies - design and use - part 1 - 1 : generic requirements - flatness considerations for electronic assemblies 印制电路板和印制电路板组件.设计和使用.第1 - 1部分:总要求.电子组件的平整度情况
The adoption of fine aggregates can reduce the separation of aggregates and improve the compactness and surface smoothness of concrete of the sidewall 配合比中用小区料作骨料，能减少骨料分离，提高边墙混凝土密实性及表面平整度。
It is used to caiibrate the thickness of slabs , and is the special machine to unify the thickness of thick - ness of slabs and normalize the smooth - ness 此系列机械对厚度不一致、不规范的板材进行切削、校平，是规范板材厚度、平整度的理想加工设备。
The resin finished cotton fabrics do not crease in wearing , have good flatness and require no ironing after machine washing , and show soft and smooth hand - feel 摘要树脂整理后的棉织物在穿着过程中不易起皱，洗衣机洗涤后平整度好、不需熨烫，手感柔软、骨爽。
It is found that ito surface roughness decreased after oxygen plasma treatment , which can improve its wetting performance and consequently improve the film performance 经氧等离子体处理后, ito薄膜的表面粗糙度减小,平整度提高,提高了ito薄膜表面的润湿性能,改善了有机物在其表面的成膜性能。
With increasing the inputting rf power further , the intensity of visible band emission increase , on the contrary , the intensity of uv band decreas . the surface also becomes rough as further increasing rf power 然而随着射频功率的进一步增加，薄膜的结晶质量降低，紫外发光变弱，深缺陷发光增强，薄膜的表面平整度变差。
One is roughness - parabolic method according to the request of " technical specifications for maintenance of highway asphalt pavement " and " technical specifications of cement concrete pavement maintenance for highway " 一种是按照《公路沥青路面养护技术规范》和《公路水泥混凝土路面养护技术规范》要求的平整度抛物线法。
Because of better conductivity , higher transparency , smoother surface and higher work function , ito ( indium tin oxide ) films are used as the transparent electrodes which are the emitting side in oled Oled显示器件经常采用ito膜作为有机发光的出射面和透明电极,要求ito膜可见光透过率、导电性、表面平整度以及功函数都很好。
Regardless of imports for carpets , carpet surface directly or knitted blankets , no matter what the color of the product is guaranteed to produce a good surface finish and flatness and uniformity of color 无论采用进口连续毡表面毡或者直接采用针织毡，无论使用何种颜色，均可保证生产出的产品具有良好的表面光洁度平整度和颜色均匀度。
