第3题:

在Excel的运算中,下列求和公式的表达有错误的是( )。

A.=SUM(D1:D4,D5,D6) B.=D1+D2+D3+D4+D5+D6

C.=SUM(D1;D6) D.=SUM(D1,D2,D3,D4,D5,D6)

第4题:


A.d1=d0+λ,d2=d0+3λ
B.d1=d0-λ,d2=d0-3λ
C.d1=d0+λ/2,d2=d0+3λ/2
D.d1=d0-λ/2,d2=d0-3λ/2

答案:C
解析:
根据劈尖角与条纹间隔的关系,轻压C端,条纹间距变大,说明B、C直径大于A。相邻条纹对应劈尖膜厚度差为λ/2,所以d1-d0=λ/2,d2-d0=3λ/2,由此解出d1、d2即可。 正确答案应为C
