求翻译：根据以上的公式可知整个信号解调部分的幅值特性除了D一个变量剩下的都是常量，因此最终的幅值特性可以用D的特性来描述，而我们最终求解的是臂长差ΔL，根据ΔL和D的关系，因此也可以通过ΔL的幅值特性来描述系统的特性：是什么意思？

Based on the above formula shows that the amplitude of the signal demodulation part of the characteristics of a variable in addition to D and the rest are constants, so the final amplitude characteristic can be used to describe the characteristics of D, and we end up solving the arm length differenc

May know the entire signal demodulation part according to above formula the peak-to-peak value characteristic to be left over except a D variable all is the constant, therefore the final peak-to-peak value characteristic may use D the characteristic to describe, but we finally solve are the reach di

According to the above formula we can see the entire signal demodulation amplitude characteristics in addition to d a variable part and the rest are constants, so the final amplitude characteristics of d can be used to describe the characteristics of, and our final solution is poor arm length δ l, a
