英文摘要：

The principle of biological genetic variation is introduced into the design process reuse to enhance the efficiency of design process and the method of design process reuse,and an optimization based on the principle of genetic engineering is put forward.As the design process gene is feature with heritability and variability of similar biological gene,the principle of design process reuse based on genetic engineering and its implementation mode are proposed.The design process gene can be reformed and changed by applying the method of biological genetic engineering to realize design process reuse and optimization.Finally,the system of design process reuse was designed as well as the application and analysis was carried out by taking the design process of some type of aircraft as an example.
