Assuming that the bare mass of the straton is very large and that the interaction of the straton and antistraton is instantaneous in the rest frame of the meson and taking the form of V0 γ,×γ5+V1γ4×γ4...Assuming that the bare mass of the straton is very large and that the interaction of the straton and antistraton is instantaneous in the rest frame of the meson and taking the form of V0 γ,×γ5+V1γ4×γ4×V2γ×γ, we solve the B-S equation for mesons. The mass formula m2=（m1+m2）2+2（m1+m2）E is obtained, where m1 （m2） is the effective mass of the straton （antistraton） inside the meson and E is the eigenvalue of the Schrdinger equation. The obtained mass spectra including both light mesons and heavy mesons agrce with experimental data. Our model may provide a possille explanation for the question why the nonrelativistic Schrdinger equation can be used even for hadronic systems composed of u, d, s stratons, though their effective mass is very small.展开更多
