粗糙度比
英文
roughness ratio-
The quality of buffer layer and thin films was analyzed by afm, xrd, rheed and xps respectively. the effect of the experimental parameters such as carbonization time, working pressure, c source gas flow rate, carbonization temperature, different carbonization gas and substrate on the carbonization process was studied firstly. it was observed that the size of particles was increased with the increase of carbonization time and the rms was opposite, but the trend was reduced while the carbonization time was long enough ; the size of particles was increased with the increase of working pressure too, and choosing a proper working pressure could get a smooth surface ; the size of particles was unobviously changed while the gas flow rate was low, but it was notability increased with the increase of gas flow rate while the gas flow rate was high enough, and a smooth surface could be also obtained by choosing a proper gas flow rate ; with the increase of carbonization temperature, the size of particles was increased, the rms is decreased and a good single - crystalline carbonization layer could be obtained, but a rough surface was formed at a excessive high temperature ; the rms of
對于碳化工藝，側重研究了碳化時間、反應室氣壓、 c源氣體的流量、碳化溫度以及不同種類的c源氣體、基片取向等因素對碳化層質量的影響，研究結果表明:隨著碳化時間的增長，碳化層的晶粒尺寸隨之變大，表面粗糙度隨之降低，但當碳化到一定時間之後，碳化反應減緩，碳化層的晶粒尺寸以及表面粗糙度的變化幅度變小;碳化層的晶粒尺寸隨反應室氣壓的升高而變大，適中的反應室氣壓可得到表面比較平整的碳化層;在c源氣體的流量相對較小時，碳化層的晶粒尺寸隨氣體流量的變化不明顯，但當氣體流量增大到一定程度時，碳化層的晶粒尺寸隨氣體流量的增大而明顯變大，同時，適中的氣體流量得到的碳化層表面粗糙度較低;碳化溫度較低時，碳化層的晶粒取向不明顯，隨著碳化溫度的升高，碳化層的晶粒尺寸明顯變大，且有微弱的單晶取向出現，但取向較差，同時，適中的碳化溫度可得到表面平整的碳化層;相比于c _ 2h _ 2 ，以ch _ 4作為c源氣體時得到的碳化層表面平整得多;比起si （ 100 ） ，選用si （ 111 ）作為基片生長的碳化層的晶粒取向一致性明顯更好。Founding - surface roughness inspection by visual tactile comparators

鑄造.用視觸覺比較儀檢驗表面粗糙度It is observed that the topography of the area with noise on a scar surface is characterized by larger surface roughness, plowing grooves, pits or adhesive joined asperities. while it is found that the topography of the scar after noise disappearance is characterized by a clear polished scar surface and a smaller surface roughness
有噪聲磨痕形貌的特徵是表面粗糙度比較大、存在不規則的犁溝、麻坑或粘著微凸體；而噪聲消失后的磨痕形貌特徵是表面粗糙度比較小、有微拋光作用發生。On a more refined level, we can distinguish degrees of roughness, intensity and shade of color.
在比較精確的水平上，我們可以區別粗糙度，強度和色度。Roughness comparison specimens - polished surfaces

顆粒含量模型說明，乾燥k /比不受孔隙度、差壓和礦物特性的的影響，但是要隨顆粒含量的粗糙度變化。The results show that, when increasing the feed rate of the grinding wheel, decreasing the rotating speed of the wafer chuck table and using coarser grit grinding wheel, the material removal rate in the wafer rotating grinding increase, the feed rate of the grinding wheel has greater influence on the material removal rate ; when suitably increasing the rotating speed of the grinding wheel, decreasing the feed rate of the grinding wheel and using finer grit grinding wheel, the wafer surface roughness can be reduced ; there exists a critical rotating speed of the grinding wheel ( about 2300rpm ), beyond which the material removal rate evidently decreases and the spindle motor current and wafer surface roughness steeply increase ; when the grit size of the grinding wheel is finer than # 2000, the material removal rate decreases and the wafer surface roughness has no obvious improvement
研究結果表明，增大砂輪軸向進給速度和減小工件轉速，採用粗粒度砂輪有利於提高磨削矽片的材料去除率，砂輪軸向進給速度對材料去除率的影響最為顯著；適當增大砂輪轉速，減小砂輪軸向進給速度，採用細粒度砂輪可以減小磨削表面粗糙度；在其它條件一定的情況下，砂輪速度超過一定值會導致材料去除率減小，主軸電機電流急劇增大，表面粗糙度變差；採用比# 2000粒度更細的砂輪磨削時，材料去除率減小，矽片表面粗糙度沒有明顯改善。Roughness comparison specimens - specification for turned, ground, bored, milled, shaped and planed specimens
