| Abstract: | 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. |

| Keywords: | : vibrating frequency step function characteristic value. |
