One solution is to maintain sufficient shear to wipe the metal surfaces constantly, since most polymer degradation occurs when polymer contacts metal for too long.
一个办法是保持足够的剪切以快速清洁机筒内表面。因为当聚合物与金属接触太长时间后会发生聚合物降解。
Based on these experimental results, a suitable mathematical theory has been deeloped that incorporates the effect of microsphere size distribution and polymer degradation on drug release.
依据这些试验结果，结合了微球大小和聚合物降解度对于药物释放的作用得到了相应的数学上的结论。
