The results of simulations show that : 1 ) both of the ann and the ga can get the good results to the one - dimension ihcp , 2 ) the two methods also can get the good results to the two - dimensions design ihcp , 3 ) the two methods have poorer anti - noise performance to the two - dimensions multi - varies ihcp . 4 ) the ga has good anti - noise performance to the two - dimensions unique - varies ihcp , nor has the ann 求解结果表明： 1 ) ann和ga对一维导热反问题均能得到满意的结果， 2 )对二维设计型导热反问题，两者也能得到高精度的解；对二维多宗量导热反问题，两者的抗噪声性能都比较差， 3 )对二维单宗量导热反问题， ga的抗噪声性能可以达到要求， ann则性能较差。
Considering the operation and expansibility of experiments , we can change the meters " parameters , the way of data processing , the structure of programme , etc . it is changed to be industrial field , which inspires students " ideas and improve their abilities of solving problem . they can adopt the factual work quickly 同时着重考虑设计型和综合型实验的操作性、扩展性：可以改变仪表参数、数据处理方式、程序结构等，变实验台为工业现场，充分激发学生思考的积极性，提高解决问题能力，使学生尽快适应实际工作要求。
According to the urgency and the necessity of reconstructing material mechanics lab , plans and suggestions were put forward in six aspects which consist of reconstructing universal material machine and photo - elastic instrument , rebuilding electrical testing lab , increasing devisable experiments , adding virtual experiments , making exhibit - boards 摘要鉴于改造材料力学实验室的紧迫性和必要性，从改造万能材料试验机、光弹仪和电测实验间，增加设计型实验项目，增加虚拟实验，制作展示板等6个方面，提出了具体方案和建议。
