On Accurate Calculation of Vibrating Frequencies for Piecewise Homogeneous string

Liu Jixi  
An accurate calculation of vibrating fregencies for piecewise homogeneoues string is given, which offers an effect approxi- maiton to frequenecies for the general nonhomogeneous vibrating string, since the latter can be approximated by the piecewise homogeneous ones.
