This text provides fast and convenient water quality testing methods for fixed-frequency spectrum impurities in the water analysis and research.
Although there is a gap from the accurate identification and detection applications, the experiment data show that the method is feasible.
Paper process focuses on fixed-frequency test vector production experiments as well as impurities in the water approach a useful attempt to and follow-up study has certain reference.
Papers on the impurities in the water given frequency spectrum analysis is a draw on the vibration signal acquisition of arrival to a detection method of frequency characteristics of the target object, the attempt will undoubtedly simplify the convenience of the motor measured.
