In this paper , we discussed the similarity between machine design process and biology growth process , especially the similarity between machine structure design process and biology embryo growth process , and point out that we should use the rule of biology embryo growth process ( morphogenesis ) to implement assembly structure design automation , and put forth a feasible plan to implement the assembly structure design automation 摘要論述了機械設計過程與生物發育過程之間的相似之處,特別是機械結構設計過程與生物胚胎發育過程之間的相似性,指出借鑒生物胚胎發育的規律(形態發生學)實現裝配結構設計自動化的可能性,并從計算機實現的角度提出了可行的步驟和方案,利用此方案可實現裝配結構的自頂向下設計。
