采用探针法测定了不同竹龄的毛竹竹青和竹黄在砂磨加工前后的表面粗糙度 ,用轮廓最大高度 (Ry)、微观不平度十点高度 (Rz)和轮廓算术平均值偏差 (Ra)三个分析因子对竹材表面粗糙度进行分析 ,并与水青冈和水曲柳等木材进行对比 ,结果表明 :竹材表面粗糙度随竹龄的增加而减小 ;竹青表面比竹黄更光滑 ;与水曲柳和水青冈相比 ,竹材外侧的表面粗糙度相对较小 The surface roughness of bamboo, bamboo and bamboo with different bamboo ages was measured by probe method before and after sanding. The surface roughness was measured by the maximum height of profile (Ry), the ten-point height of microscopic roughness (Rz) Ra). The results showed that the surface roughness of bamboo decreased with the increase of bamboo age; the surface of bamboo green was more than that of bamboo Smooth; Compared with Ash and Fagusia, the outer surface of the bamboo has a relatively small surface roughness
