计算说明：
$$ \alpha_{t}=atan\left ( \frac{\tan \alpha_{n} }{\cos\beta } \right )$$
$$ inv\ \alpha_{wt}=2\left ( \frac{x_{n1}+x_{n2}}{z_{1}+z_{2}} \right )\tan\alpha_{n}+inv\ \alpha_{t}$$
$$y=\frac{z_{1}+z_{2}}{2\cos\beta } \left ( \frac{\cos\alpha _{t}}{\cos\alpha _{wt} } -1 \right )$$
$$d=\frac{zm_{n}}{\cos \beta }$$
$$d_{b}=d\cos\alpha_{t}$$
$$d_{w}=\frac{d_{b}}{\cos\alpha_{wt}} $$
$$h_{a1}=(1+y-x_{n2})m_{n}$$
$$h_{a2}=(1+y-x_{n1})m_{n}$$
$$h=(2.25+y-x_{n1}-x_{n2})m_{n}$$
$$d_{a}=d+2h_{a}$$
$$d_{f}=d_{a}-2h$$
