Abstract：
Starting from the assumption of the instantaneous interaction and supposing that the effective couplings between the quark and the antiquark arc spin independent, an unified solution of the 3-dimensional wave functions of the mesons with the natural J^pc is obtained, where J can take all the possible values. This type of the solutions has only one independent space wave function, which satisfies a second order equation. In the heavy quark approximation, adopting the linear potential, the mass spectrum of the new and the old mesons can be roughly explained by the formula of the energy cigenvalue of this equation.
