“…For orthogonal experiment results, a range analysis was conducted to identify the significance degree of different factors on the viscosity of modified SiC slurry. The average values of viscosity for three levels in every factor are defined as K 1 j , K 2 j , K 3 j ( j = A , B , C , D )
42,43 . For example, the calculation on the average value of A factor is shown as follows:
