粗糙表面

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。

When the saturated vapor of pure R11 or R113 was condensed on the PF tubes under free convection conditions, the HTCs (based on the outside area of the base tube, the same be1ow) were 14 to 20 times those of the smooth tube because the condensate surface tension made the condensate film on fin surfaces thin and the rough saw-toothed fin surfaces disturbed the boundary layer in the condeneate film.

纯R11、R113的饱和蒸气在大空间花瓣形翅片管上冷凝时，由于凝液的表面张力将翅片表面上的液膜拉薄以及粗糙的锯齿形的翅片表面扰乱了凝液膜内的流动边界层，传热膜系数（以坯管外表面积为基准，下同）是光滑管的14—20倍。
