 1. 配料計算：


(c). 計算過程
(注意：配料總重量為四種配料重量之和)
C₁=50x3.6/100+50x0.2/100+1x99/100
=1.80+0.10+0.99
=2.89
Si₁=50x1.80/100+50x0.2/100+1x50/100
=0.90+0.10+0.5
=1.50
C₂=2.89(1+0.1)=3.179
Si₂=1.50(1-0.1)=1.350
C=3.179x100/102=3.117=____1____ %
Si=1.350x100/102=1.324=____2____%
CE=3.117+1/3(1.324)=3.558=____3____ %
