Abstract：
In this paper,the authors find a transformation which connects the covariant formalism with the light-cone formalism in bosonic open string theory,which leads to the connection between covariant statevectors and light-cone statevectors,and yields an orthogonal complete set of states in covariant formalism and a physical projective operator for arbitrary space-time dimension D and intercept of Regge trajectory α(0).The later reduces to the result given by L.Brink and D.Olive in the case of D=26,α(0)=1.Finally,we explicitly show that in covariant formalism,the mass square operator M ²≥0 except for the tachyon of ground state.
