摘　　要：本文简单介绍了遗传算法的理论基础和计算流程，讨论它的优越性能。结合反演单向纤维样品独立弹性常数的实验，探讨了遗传算法在此领域中的应用，与前反演结果相比较，验证了该算法的有效性。The theoretical basis, calculation procedures and advantages of genetic algo- rithms are briefly introduced. As an example of their applications, the elastic constants of a unidirectional fiber composite plate are inversely deduced by the genetic algorithms from ultrasonic velocity measurements. The elastic constants obtained are demonstrated to have higher accuracy compared with our previous results.
