摘要： 利用形式化规格说明语言—— B语言对软件需求进行了严格定义，在严格的数学基础上进行软件开发，以获得更好的软件性能。利用形式化方法的需求分析，有助于发现需求中隐含的不一致性、二义性和不完整性，对其进行更深入精确的理解，从而进行规范化管理。

Abstract: The paper models software requirement in the form of formalized specification language B, develops software based on a precise mathematical framework in order to achieve better software performance. It is helpful to describe requirement with formal methods, which keeps the consistency, unambiguity and completeness. It also makes further and precise understanding of requirement, so as to manage it more standardfully.
