The modeling grammar of B language is compatible with Systems Biology Markup Language ( SBML ), current actual standard. As an interactive interpreting programming language, B language, combined with its simulator, provided a convenient way for calculation of the complex biological model. B语言的建模语法根据系统生物学标记语言设计,符合当前通行标准,并且B语言具有交互性解释型编程语言的特征,配合构建的仿真环境,就能方便的对模型进行仿真和计算。
