二 标准距离

{
get { return _stdDistance; }
set => SetProperty(ref _stdDistance, value);
}
/// <summary>
/// 卡控阈值
/// </summary>
private double _thre = 0;
public double Thre
{
get { return _thre; }
set => SetProperty(ref _thre, value);
}

<Label Content="标准距离:" Margin="10"/>
<TextBox x:Name="tbx_STDDistance" Text="{Binding AppParameter.StdDistance}" Margin="10"/>
<Label Content="卡控阈值:" Margin="10"/>
