Abstract：
A quantization scheme for boson string with Weyl ordering is proposed in this paper.Inconsistency between Hermiticity requirement in coordinate space and normal ordering in oscillator space is avoided.The Virasoro algebra of Nambu-Goto string with Weyl ordering were derived by virtue of principal value sum where all central terms vanished.We also calculated the angular momentum operators of the string and their commutation rules,and reached the conclusion that dimension of the string is 26(D=26).
