| 摘 要： | 红外无损检测的本质可归为热传导反问题的求解。利用通过解析法求解热传导正问题得出的结论，提出基于遗传算法优化求解的红外无损检测缺陷信息新方法，该算法采用浮点数编码，并采用多遗传算子并行损作，不仅获得了好的结果，而且维系了种群的多样性。模拟实验验证了算法的鲁棒性和可靠性。

| Abstract: | The essence of infrared nondestructive testing is to find a solution to inverse problem of heat conduction. A novel solving method to this problem based on genetic algorithm was proposed. It uses floating point coding technique and multi-operators parallel style to improve the precision of the result and to maintain the variety of the group. The simulation experimental results prove that this method behaves a strong robustness and reliability. |
