摘　　要：考虑到演化算法的鲁棒性和普适性 ,可用它来研究H-和He的外场特性 .H-和He在外场中基态能的计算问题可转化为一个函数优化问题 ,用MCI方法处理H-和He的定态波函数 ,用演化算法求体系的基态能 ,得到了高精度的结果 。Considering the robustness and commonness, it uses the evolutionary algorithm to calculate the characteristic of H - and He in outfield. The calculation for ground state energy of H - and He can be converted to a problem of function optimization. At first the MCI method is adopted to deal with state wave functions of H - and He, then the evolutionary algorithm calculates their ground state energies. Results show that it can obtain much more accurate results, and compared with other algorithms, it's more efficient. [
