c. 計算過程： (注意：配料總重量為四種配料重量之和) 

 C₁=50x3.3/100+50x0.2/100+1x99/100

=1.65+0.10+0.99

=2.74 

Si₁=50x2.2/100+50x0.2/100+1x75/100

=1.10+0.10+0.75

=1.95

Mn₁=50x0.6/100+50x0.6/100 =0.60 

C₂=2.74(1+0.15)=3.151

Si₂=1.95(1-0.10)=1.755

Mn₂=0.60(1-0.15)=0.510

C=3.151x100/102=3.089=____1____%

Si=1.755x100/102=1.721=____2____%

Mn=0.510x100/102=0.500=____3____%

CE=3.089+1/3(1.721)=3.663=____4____%
