biodegradation rate meaning in English

生物降解速率

In this work , pluronic f127 was used as a progen and different biodegradation rate and surface property as amorphous calcuim phosphate , a - calcuim triphosphate , - calcuim triphosphate and a / p - calcuim triphosphate were selected to make three - dimensional porous composites with plla . in the phase separation of pure plla or cp / plla composite system the ppo block of pf127 can aggregate plla clew to induce phase separation . this resulted big round pores of 50 ~ 300 m and uniform ladder - like structure of 400 ~ 1000 m
具体结果如下：浙江大学硕士学位论文在单纯的聚乳酸以及钙磷酸盐/聚乳酸复合体系的相分离过程中， pf127的ppo链段对plla链段有聚集作用，促进相分离过程，在不同溶剂中分别可得到孔径在50一300林m的较大的圆孔和有序度为400一1000林m的梯状孔，孔隙率为80 % ~ 93 % 。
