中文摘要：

针对生物信息处理过程中难于找到相关程序进行序列分析的问题，自行设计一套数据处理软件．经实际应用，软件可用于处理生物数据库Transterm中获得的海量原始数据．文中简介Transterm数据库中所需信息的格式，并说明BYSJ软件的设计目标、实现原理、源代码，以及软件的功能及使用．

英文摘要：

In the course of bioinformation processing, it is necessary to design some small software for sequence analysis in answering specific inquiry. BYSJ is just the software designing for processing enormous initial data, which are obtained from Transterm database. The authors describe the format of the file in Transterm database and on this basis, explain the design objective, implementation principle, source code of BYSJ software and also its fanction and usage. This is a successful attempt of software development in the field of bioinformatics.
