查询词典 roughness

The results showed that under the same polishing parameters, the particle size exerted an important influence on MRR and surface quality during unfixed-abrasive polishing, but played a less role during fixed-abrasive polishing. A fine surface roughness of R 1.5 nm was achieved by using diamond fixed-abrasive pad, and the function of self-conditioning was well realized.

Wall roughness and paint sheen can affect the lightness of any color. Smooth surfaces and gloss paints reflect maximum light to make a color seem lighter. Rough-textured walls and flat sheen paints hold more shadow and minimize the lightness of a color.

墙面的粗糙度和油漆的光泽度会影响任何颜色的亮度，平滑的墙面和光亮的油漆反射出的光使得颜色看起来更淡，粗糙的墙壁和屋顶储存了更多的阴影从而减弱了颜色的亮度。

This offers greater ability to absorb the surface roughness typical of off road routes because the wheel withdraws lengthways without affecting the steering and the antisquat angle has been increased.

这提供了更大的能力来吸收表面粗糙度典型的越野路线的，因为这轮退出，而不会影响转向和antisquat角度纵向有所增加。

Machining capability includes machining quality and cutting efficiency. Machines machining capability is usually assessed by the tiptop precision and superficial roughness that can be reached of the being processed part. The cutting efficiency is usually assessed by the most limit value of removal rate or cutting dosage.

机床的加工性能包括其加工质量和切削效率两个重要的方面，通常甩被加工零件能达到的最高精度和表面光洁度来评定机床的加工质量，用金属切除率或切削用量的最大极限值来评定机床的切削效率。

Using the relative reflection as weighting factor, the weighted mean of the surface albedo over Dunhuang Gobi in typical arid region is calculated and its values are 0.255 ± 0.021. After canceling the interference of the buildings, the mean values of the roughness length averaged with logarithm is 0.0019 ± 0.00071 m. After removing the influence of the oasis, the soil wetness factor computed with data under condition of no precipitation is 0.0045. After removing the influence of the precipitation .the mean values of the soil heat capacity over Dunhuang Gobi in typical ac-id region is 112 × 10 ~6 m~(-3)K~(-1), a bit smaller than the values observed i n HEIFE. But the soil heat diffusivity and conductivity are about one of those observed in HEIFE. The soil water content over Dunhuang Gobi in typical synoptic condition is very little and does not exceed 1% basically.

并且利用相对反射为权重加权平均，计算得到典型干旱区敦煌荒漠戈壁的平均反射率为0.255±0.021；剔除建筑物干扰后，利用对数平均法计算的粗糙度长度平均值为0，0019±0.00071 m；剔除绿洲影响后，用无降水影响的资料确定出土壤湿度影响因子为0.0045；剔除降水影响后，用观测资料计算的敦煌典型干旱区荒漠戈壁的热容量平均值为1.12×10~6m~（－3）K~（－1），比&黑河试验&在戈壁和在其它沙漠观测的有关值略小一些，但热扩散率和热传导率都比&黑河试验&在戈壁观测的值小一倍左右；观测的敦煌戈壁典型天气条件下的土壤含水量非常小，基本上不超过1％。
