摘　　要：膜系初始结构优化设计是膜系优化设计的关键。针对多膜料设计 ,提出了一种新的膜系初始结构优化设计算法 ,将膜系的初始设计视为组合优化问题 ,采用遗传算法 ,求得组合的最优解。给出了算法的原理 ,并给出了相应的设计实例。结果表明 ,本算法是一种简单、有效。The original structure optimization of optical multilayer is important for the whole design of the optical thin films. To the design with a few materials, a new method is given. Because the design of the original structure of optical multilayer can be looked as a optimization problem about the combination of the parameters of the thin films, the GA (Genetic Algorithm) can be used to get the beast solution. The theory of the GA is explained, a serial design examples are given. The results indicate that the way presented above is simple, effective and general for the original structure.
