摘　　要：通过对蝌蚪图中的硬热圈重求和的方法自洽地计算了标准模型在有中性流作用下的高温有效势到（ｇ３，ｇ’３）级，克服了通常计算中存在的困难。By using the Fresummation of the hard thermal loops in the tadpole diagrams,the effective potential of order(, g3,g′3)is consistently calculated in the standard model with neutral current at high temperature and the difficulties in the naive calculation are overcome.It is proved that the electroweak transition is of the firstorder and the critical temperature is given.

关 键 词：有效势 相变 标准模型 自治计算
