以下是一个简单的 VB 实现四等水准测量的代码:
```
Private Sub btnCalculate_Click()
'定义变量
Dim h1 As Double, h2 As Double, h3 As Double, h4 As Double
Dim d12 As Double, d23 As Double, d34 As Double
Dim f12 As Double, f23 As Double, f34 As Double
Dim b As Double, l As Double, h As Double
'获取输入数据
h1 = CDbl(txtH1.Text)
h2 = CDbl(txtH2.Text)
h3 = CDbl(txtH3.Text)
h4 = CDbl(txtH4.Text)
d12 = CDbl(txtD12.Text)
d23 = CDbl(txtD23.Text)
d34 = CDbl(txtD34.Text)
'计算较差
f12 = h1 + d12 - h2
f23 = h2 + d23 - h3
f34 = h3 + d34 - h4
'计算平差数值
b = (f12 + f34) / 2
l = (f23 - f12 + f34) / 2
h = (h1 + h2 + h3 + h4) / 4
'输出结果
txtB.Text = Format(b, "0.00")
txtL.Text = Format(l, "0.00")
txtH.Text = Format(h, "0.00")
End Sub
```
该代码实现了四等水准测量的计算,用户需要输入测量数据,程序会自动计算较差和平差数值,并输出结果。需要注意的是,该代码仅供参考,实际使用时需要根据实际情况进行修改和完善。
