汉英语境1
英译术语:
mean semi-squared difference
汉语语境:
利用半方差法计算实际磨削表面轮廓的分形维数。结果表明，分形维数D越大，轮廓曲线越复杂，同时D与传统的粗糙度评定参数轮廓算术平均偏差Ra、轮廓均方根偏差Rq及轮廓支承长度率t_p呈单调增长关系，但线性关系不明显。分形维数D是一个反映机加工表面特性的综合参数。
英语语境:
The actual calculation of the fractal dimension of the surface profile grinding method uses semi-variance. The results show that the fractal dimension D is a larger and more complex profile curve, while D and the traditional profile roughness parameters assessment arithmetical mean deviation Ra, the root mean square deviation Rq and contour profile bearing length ratio showed a monotonically increasing relationship t_p, but linear relationship is not obvious. Fractal dimension D is a comprehensive parameter reflects the machined surface characteristics.
