本文利用超POInCArE张量运算，构造了一个3维n＝1超引力理论，给出了一般的拉氏密度，详细讨论了超对称自发破缺机制及超HIggS效应.By using super-Poincare tensor calculus, we construct an N = 1 supergravity theory in 3-dimensions, and the most general Lagrangian is obtained.The mechanism of spontaneous supersymmetry breaking and super Higgs eFFect are studied in detail.国家自然科学基金;福建省自然科学基
