标题： Gauge and Lorentz Covariant Quark Propagator in an Arbitrary Gluon Field

摘要： 在存在任意胶子场的情况下，夸克传播子按胶子场及其导数的幂次依次以规范和洛伦兹协变的方式进行计算。 结果与传播子两端连接路径无关，且在胶子场为零的平凡情况下，领先阶结果与精确传播子一致。 显示英文摘要

摘要： The quark propagator in presence of an arbitrary gluon field is calculated gauge and Lorentz covariantly order by order in terms of powers of gluon field and its derivatives. The result is independent of path connecting ends of propagator and leading order result coincides with the exact propagator in the trivial case of vanishing gluon field.
