k = 0.85
Case Else
k = 0.82

End Select

错误的 不行啊

Answer 1

Select Case x
Case Is < 10
k = 1
Case is < 20
k = 0.95
Case is < 50
k = 0.9
Case is < 100
k = 0.85
Case Else
k = 0.82
End Select

或者你用IF语句来实现
if x<10 then
k=10
elseif x<20 then
k=0.95
elseif x<50 then
k=0.9
elseif x<100 then
k=0.85
else
k=0.82
end if

Answer 2

Select Case x
Case Is < 10
k = 1
Case 10 <= x and x < 20
k = 0.95
Case 20 <=x and x < 50
k = 0.9
Case 50 <=x and x < 100
k = 0.85
Case Else
k = 0.82
