摘　　要：在量子力学中,我们常用变分法和微扰法来求解近似问题。但在运用微扰法计算过程中,微扰项必须很小才可以使用,很难求精确解,对解决某些特定问题具有一定的局限性。而变分法则不受此限制。为此,下面运用变分法通过计算对基态锂原子的能量和波函数进行探解。In quantum mechanics,we use variation methods and perturbation methods to solve approximate problems.But in the application process of perturbation methods,the perturbation must be very tiny,and it is difficult to find the exact solution,which has some limitations to solve certain specific problems.While the variation methods are not subject to this restriction.Therefore,this paper will use the variation methods to analyze the energy and wave function of the ground-state lithium atom.
