摘　　要：计算了J^(PC)=1^(-1) 三胶子流的两点函数并推导出其量子色动力学求和规则;在零宽度近似下,得到了矢胶怪球1^(-+)的质量mv=1.9GeV,这与格点规范计算结果比较接近。The two-point function of the JPC = 1 + exotic vector gluonic current is cal culated by including both the perturbative and non-perturbative contributions of QCD. Using the zero-width approximation, the mass of the 1 - vector odd-glueball is then estimated in the framework of QCD sum rules. Our result agrees with the prediction from the calculation of the lattice gauge theory.
