The cover is made from a biodegradable polymer which has a high quality stable finish but biodegrades easily in compost. 这种外壳是用一种可生物降解的聚合物制成的,这种聚合物的外涂层质量高,稳定性强,但是在堆肥中很容易生物降解。
The experimental contrast of the same strain of bacteria that biodegrades phenol in immobilized cell state and in free cell state proved that red brick fragments is a fine carrier material. 通过同一菌种在固定状态和游离状态降解含酚废水的实验对比,证明红砖碎粒是一种优良的载体材料。
Polylactic acid ( PDLLA), which gradually biodegrades into water and carbon dioxide, has good biocompatibility and biodegradability. Therefore, the research of drug carrier materials is now focused on families of polylactic acid. 聚乳酸是一种具有优良生物相容性和生物降解性的聚合物,可逐渐降解为二氧化碳和水,因此成为当今药剂载体材料中的一大研究热点。
