粗糙

The velocity of a river is determined by the slope,the depth,and the roughness of the riverbed.

Crystals of pure quartz, usually called rock crystal, are coarseness, colorless, and transparent.

参考译文：纯净石英的结晶，通常称为岩石水晶，是粗糙的，无色的，透明的。

The vermilion rockfish has scales on the bottom of the lower jaw which make it rough to the touch.

Many people like to glide along the sidewalk on roller skates. They owe a vote of thanks to Joseph Merlin of Belgium. He invented a kind of roller skate back in 1760. His skates provided a pretty bumpy ride, however.

许多人喜欢沿街边的人行道溜旱冰，他们应该感谢比利时人约瑟夫默林。1760年，约瑟夫默林发明了一种类似的旱冰鞋，然而，他的旱冰鞋因为粗糙使得滑行相当颠簸的。

The results indicate that, rolling with lubrication can reduce friction and improve production efficiency. The surface roughness and quality of aluminum after rolling are also decreased at same time.

结果显示轧制润滑可以减小摩擦，提高生产效率；同时又使得轧后铝板表面粗糙度降低，表面质量明显改善。

Faults--Coarseness; snipiness; overshot or undershot; eyes round or bulgy or light in color; exaggerated Roman nose; head not surmounted with topknot.

缺点——粗糙；上颚突出或下颌突出；眼圆或突出或颜色发浅；夸张的罗马鼻子，头部未被顶髫覆盖。

The surface morphology was studied by the AFM also.Though the average size of grain and the RMS(root-mean-square) value of the two samples is diffe-rent,comparing sample A with B, the result shows that sample A is more smooth.

通过原子力显微镜，对生长在两种衬底上薄膜的表面形貌做了观察，其晶粒的大小与表面粗糙度有一定的差别，表明二者都是以柱状形式生长的。

By using the KDMRF-1000F MRF polishing machine and KDMRW-1 water based MR fluid,one K4 flat work piece (80 mm in diameter) and one K9 sphere work piece (145 mm in diameter) were polished,experiments show that work piece one has a peak-to-valley value of 55.3 nm and a root-mean-square value of 5.5 nm;and work piece two has a PV value of 40.5 nm and a RMS of 5 nm,which indicates that the surface roughnesses of two work pieces have been improved obviously.

实验显示，样件一面形收敛到PV值55.3 nm，RMS值5.5 nm；样件二面形收敛到PV值40.5 nm，RMS值5 nm；样件的表面粗糙度均有显著改善。结果表明，磁流变修形技术具有高精度、高效率、高表面质量的特点。

The surface morphology and root-mean-square roughness had been characterized by atomic force microscopy.

结果表明，随着工作气压的升高，膜层的结构变疏松，薄膜的折射率和均方根粗糙度都随之减小。
