At last, an intelligentized testing instrument for electric wire high frequency carrier wave channels is developed.
在此基础上，研制开发出了一套智能化电力线高频载波通道测试装置。
Its carrier wave is a kind of the bearing's inherent vibration with high frequency, and its modulating wave is a pass vibration corresponding to the local defect.
该调幅振动的载波为滚动轴承的某一高频固有振动，而调制波为与缺陷或损伤有关的通过振动。
