By analysis it is shown that the maximal modulation sensitivity comes from an appropriate end reflection coefficients of OWFPM for a certain light source spectrum width. 由分析得到，对于确定的光源光谱宽度，波导端面反射率只有取合适的值，才能取得最灵敏的调制效果。 - 2
We can monitor many parameters and characteristics by measuring TEN, such as surge frequency, spectrum width, threshold current, mode jump and stability of output light power. 通过对激光的电噪声的测量可以监测激光器的诸多参数和特性，如弛豫频率，谱线宽度，阈值电流，模式跳变及输出光功率是否稳定等。 - 3
Fixing the spectrum width of the weather echo signals, we change theirs mean Doppler frequency and filter them using regression filter. After filtering, we analyze the attenuation of them. 在天气回波信号谱宽固定的情况下，通过改变天气回波信号的平均多普勒频率，分析了回归滤波器对它的衰减情况。
