摘　　要：The explicit common eigenvectors for complex scalar fields φ (x) and φ+ (x) are derived . They span an orthonormal and complete space. Based on this, the charge conjugate unitary operator and the operator which generates Bogolyubov pseudo-particles transformation can be neatly derived. It is emphasized that | ξ】 is different from the direct product of two independent eigenvectors respectively belonging to two real scalar fields, and | ξ 】 is named the correlated eigenstates of φ( x) and φ^+ (x).The explicit common eigenvectors for complex scalar fields ?(x) and ?+ (x) are derived. They span an orthonormal and complete space. Based on this, the charge conjugate unitary operator and the operator which generates Bogolyubov pseudo-particles transformation can be neatly derived. It is emphasized that |ξ? is different from the direct product of two independent eigenvectors respectively belonging to two real scalar fields, and |ξ? is named the correlated eigenstates of ?(x) and ?+ (x).
