Because of the composite material is heterogenetic , we can design a composite material with optional strength and stiffness to meet the need as a special construction 由于复合材料的各向异性,可以设计出有任意方向的强度、刚度的材料,能够满足特殊机身结构的要求。

In one word , the methods for producing acellulace matrix have not been standardized . in this study , we want to select the best way to produce acellular matrix . we also use immunohistochemical method for detecting the magor heterogenetic antigen a - galactosyl residues ( a - gal ) in acellular matrix 并应用免疫组化的方法检测脱细胞后基质的主要异种抗原，用种植实验观察异种机体对脱细胞生物基质的组织反应倩况，另在其上种植鼠成纤维细胞以观察脱细胞生物基质的细胞毒性和细胞相容问题。
