在重子手征微扰理论的框架内，我们计算了中子的电偶极矩和λ。它们是由存在真空角θ（o）时有效拉格朗日量的强CP破坏项引起的。这样的拉格朗日的建设概述，我们能够给一个估计θ（o）。
We calculate the electric dipole moments of the neutron and the Lambda within the framework of heavy baryon chiral perturbation theory. They are induced by strong CP-violating terms of the effective Lagrangian in the presence of the vacuum angle theta(o). The construction of such a Lagrangian is outlined and we are able to give an estimate for theta(o).
