| Abstract: | This paper was studied the dynamic law and is surveyed YoungJs modulus and hangs to prick the size of some seats and sample in the experiment and hangs the relation between material and specifications and the frequency of resonance of thread, and introduced with interpolation method and the extension law to define that node the method of frequency of resonance as several kinds are quick and the method accurately to distinguish the true and false resonance signal. |
