Because sequence data increase rapidly in biology sequence database , it is very exigent to develop algorithms that have high biology sensitivity and efficiency 随着生物序列数据库中序列数据的激增，开发兼有高度生物敏感性和高效率的算法就显得非常迫切。
2.
The research contents are improved and innovated algorithms of sequence alignment in bioinformatics . these algorithms are advanced more evidently than traditional algorithms in biology sentivity and computing efficiency . the software system based on these algorithms can offer sustainment for bioinfromatics research and practice 本文的研究内容是生物信息学中序列比对的改进与创新算法，经过实际测试，其生物敏感性和运算效率较之传统算法均有所提高，在此算法基础上开发的系统平台软件可以为生物信息学的研究及实践提供一定支持。
