摘要
采用截断本征方程的方法研究２＋１维ＳＵ（２）格点规范场的胶球质量及胶球波函数．计算结果表明：五阶胶球质量ｍ／ｅ２与五阶真空波函数的一样没有表现出良好的收敛行为，在１／ｇ２＞０．８区间，胶球质量逐渐下降。胶球波函数和在时，趋于平稳，有较好的标度行为．
The method of trUncating eigenvalue equations is used to study glueballmass and glueball wavefunchon. The results of calculahon are (1) the fifth orderglueball mass shows no good convergent behavior as uo of fifth-order vacuum wave- function. At region 1/ g2 > 0.8, the glueball mass descends gedully. (2) At region1/ g2 > 0.8, the gluball wave funchon become steady, and shows good scaling.
