摘　　要：计算了０＋＋三胶子标量流的两点函数，其中计及了直至量纲为６的凝聚项的贡献．在＂零宽度共振态加连续谱＂的谱函数模型中，得到了０＋＋三胶子标胶球的量子色动力学求和规则，由此定出了该标胶球的质量．The two-point function of the 0++ three-gluon scalar current is calculated byincluding not only the perturbative contribution but also the non-perturbativecontributions of condensates of dimension up to six The QCD sum rules for the0++ three-gluon scalar glueball are deduced in the 'zero-width resonance pluscontinuum' model. The mass of this glueball is determined to be 1.45GeVapproximately.
