摘要
阐述了花岗石表面轮廓的特点,提出先对原始轮廓曲线进行高斯滤波,然后再进行粗糙度计算的方法;并对用高斯滤波和最小二乘中线两种方法计算的粗糙度进行了比较,认为高斯滤波方法更适合花岗石表面轮廓的粗糙度研究。其计算方法较为可靠和简捷。
The characteristics of granite surface profiles are described. Gauss filtering has been adopted on original granite surface profile curves, and then research its roughness. Two roughness datum have been compared that been calculated by Gauss filtering and least squares midline. It is an available and fast computation method for roughness to granite surface profiles.
