The term garbage collection describes the automated process of finding previously allocated memory that is no longer in use in order to make the memory available to satisfy subsequent allocation requests. We have reviewed existing papers and implementations of GC, and especially analyzed Boehm’ s C codes, which is a real-time mark-sweep GC running under Linux and ANSI C standard. In this paper, we will quantitatively analyze the performance of different configurations of Boehm’ s collector subjected to different workloads. Reported measurements demonstrate that a refined garbage collector is a viable alternative to traditional explicit memory management techniques, even for low-level languages. It is more a trade-off for certain system than an all-ornothing proposition.

达那唑(Danazol),是一合成的17α-乙炔睾酮的衍生物,是一个十分有效的治疗子宫内膜异位的药物,常用的给药方法为口服。但口服的副作用很大,主要为对肝的影响。近来有研究表明阴道给药可克服肝脏首过效应,大大减少用药量减轻毒副反应,所以我们将达那唑制成阴道给药用膜剂。 本研究选用聚乙烯醇(PVA)0486和羟丙 甲基纤维素(HPMC)E50为膜材,采用刮板法制备达那唑阴道膜。 为了提
