我是VBA编程的新手。我正在尝试编写一个热容量函数,可以选择温度和单位,以及物质的相位。我已经有了代码,我创建了一个宏来调试它,因为它不断得到预期的数组错误。
以下是整个代码:
Sub Macro1()
'
' Macro1 Macro
'
Dim A As Double
Dim B As Double
Dim C As Double
Dim D As Double
Dim E As Double
Dim Temp As Double
Dim Bleh As Double
A = ThisWorkbook.Sheets("Heat Flows").Range("D3")
B = ThisWorkbook.Sheets("Heat Flows").Range("E3")
C = ThisWorkbook.Sheets("Heat Flows").Range("F3")
D = ThisWorkbook.Sheets("Heat Flows").Range("G3")
E = ThisWorkbook.Sheets("Heat Flows").Range("H3")
Temp = ThisWorkbook.Sheets("Heat Flows").Range("I3")
Bleh = MolarHC("K", "Gas", Temp, A, B, C, D, E)
End Sub
Function TK(Opt As String, Temp As Double)
If Opt = "C" Then
Temp = Temp + 273.15
ElseIf Opt = "K" Then
Temp = Temp
End If
End Function
Function MolarHC(Opt As String, Opt1 As String, Temp, A, B, C, D, E)
Dim TK As Double
Dim H As Double
TK = TK(Opt, Temp)
Select Case Opt1
Case "Gas"
H = A + B * Excel.WorksheetFunction.Power(((C / TK) / Excel.WorksheetFunction.Sinh(C / TK)), 2) + D * Excel.WorksheetFunction.Power(((E / TK) / Excel.WorksheetFunction.Cosh(E / TK)), 2)
Case "Liquid"
H = A + B * TK + C * Excel.WorksheetFunction.Power(TK, 2) + D * Excel.WorksheetFunction.Power(TK, 3) + E * Excel.WorksheetFunction.Power(TK, 4)
End Select
End Function
Function MassHC(Opt As String, Opt1 As String, Temp As Double, A As Double, B As Double, C As Double, D As Double, E As Double, MW As Double)
Dim H As Double
Dim MHC As Double
H = MolarHC(Opt, Opt1, Temp, A, B, C, D, E)
MHC = H / MW
End Function
在工作表函数中调用函数时,我也无法使函数返回值。我尝试将函数的名称更改为变量,如另一篇文章中所述,但我对预期的数组错误进一步陷入困境。
答案 0 :(得分:0)
您需要对函数进行编码以实际返回值:
Function TK(Opt As String, Temp As Double) As Double
If Opt = "C" Then
TK = Temp + 273.15
ElseIf Opt = "K" Then
TK = Temp
End If
End Function
