摘要
以正则变分和线性变分函数为基础,对互补变分原理作了论证,推导出二阶能量修正的上界和不受任何条件限制的下界,对具体计算方法作了详细的研究,得出互补变分原理在微扰理论近似中的应用.所求氢原子和极化率结果比一般的变分法的微扰法所得结果更接近于实验值,并指出这理论可以推广应用到激发态或处理高阶修正问题.
<Abstrcat> Basing on the regular variation function and the linear variation function, correction the complementary variation principle is proposed. The upper limit of the second energy correction as well as the unconditioned lower limit are deduced. It concludes that the result of the polarizability of hydrogen atom is more close to the experimental value than that resulted from the common variation and perturbation theories. As a result, it points out this theory can be introduced to use in the excitation condition and to resolve the higher expurgation problem.
