如果我们要计算两种非离子表面活性剂混合后的HLB值，下列哪个公式适用。设W[img=~/QImg/Tiles/YA25_124_17_1.gif]、W[img=~/QImg/Tiles/YA25_124_17_2.gif]为表面活性剂的质量，HLB[img=~/QImg/Tiles/YA25_124_17_1.gif]和HLB[img=~/QImg/Tiles/YA25_124_17_2.gif]为A、B两种表面活性剂的HLB值

A、B两种表面活性剂的HLB值
A、HLB[img=~/QImg/Tiles/YA25_124_17_1.gif]+HLB[img=~/QImg/Tiles/YA25_124_17_2.gif]
B、(HLB[img=~/QImg/Tiles/YA25_124_17_1.gif]×HLB[img=~/QImg/Tiles/YA25_124_17_2.gif])[img=~/QImg/Tiles/YA25_124_17_3.gif]
C、(W[img=~/QImg/Tiles/YA25_124_17_1.gif]×HLB[img=~/QImg/Tiles/YA25_124_17_1.gif]+W[img=~/QImg/Tiles/YA25_124_17_2.gif]×HLB[img=~/QImg/Tiles/YA25_124_17_2.gif])／(W[img=~/QImg/Tiles/YA25_124_17_1.gif]+W[img=~/QImg/Tiles/YA25_124_17_2.gif])
D、(HLB[img=~/QImg/Tiles/YA25_124_17_1.gif]×W[img=~/QImg/Tiles/YA25_124_17_1.gif]×HLB[img=~/QImg/Tiles/YA25_124_17_2.gif]×W[img=~/QImg/Tiles/YA25_124_17_2.gif])[img=~/QImg/Tiles/YA25_124_17_4.gif]
E、(HLB[img=~/QImg/Tiles/YA25_124_17_1.gif]+HLB[img=~/QImg/Tiles/YA25_124_17_2.gif])／2
