通过对不同结构材料的吸波性能研究，结果表明，材料结构设计合理的情况下，多层材料的吸波性能优于单层材料的吸波性能。
In sso , the thickness of each stack of the laminate must be integer times as thick as that of single ply , the angle of each stack of the laminate is selected from a set of standard angles , and the stacking sequence can change arbitrarily . when material and ply angles of the laminate are selected , ga is used to giye the optimal laminate that meets the given requirements of thickness and geometry factors
在550中，层合板各分层的厚度必须是单层材料厚度的整数倍，铺层角取作一些标准的角度，各分层在层合板厚度方向上的相对位置可任意变化，利用ga求出满足给定厚度和几何因子要求的层合板最优铺层结构。
