d、面等级标准：
surface classification standard
如果一个表面有多个不良，那么所有不良的总和来决定此表面不良是否超标。(对于划痕，则把所有划痕的长度相加之和来决定是否超标，对于圆形不良，则其直径和来决定是否超标)
If one surface has more than one defect, the sum of all the defects will determine the final level of defect. (As for the scratch, the sum of defect should be the
total length of all scratches, and as for spot, the sum of defect should be the
sum of diameter of each spot.)
