Fig. 9. The final-result trace of the two-point-vibration measurement after MA-MD processing. (a) Two vibration signals can be identified when N = 5; (b) Only the 500-Hz vibration can be identified when N = 10; (c) Both of the vibrations are lost when N = 20. The MA window width is 5.图9. 经MA-MD处理后的两点振动测量最终结果轨迹。(a) 当N=5时，可识别出两路振动信号；(b) 当N=10时，仅能识别出500Hz的振动信号；(c) 当N=20时，两路振动信号均丢失。MA窗口宽度为5。
