摘　　要：有效的软件变化追踪方法是实施软件演化的关键.基于需求信息传播与建模、需求变化信息传播路径和需求变化信息跟踪方法三个层面,阐述了软件变化跟踪的整体过程框架;给出了基于变化起源跟踪矩阵、变化对象跟踪矩阵、变化构件跟踪矩阵、以及可达矩阵的功能变化传播记录方法;凭借矩阵运算,描述了功能变化跟踪的具体实现,并给出了实施变化所付出代价高低的初步判定方法.对软件维护甚至软件演化研究具有一定的借鉴意义.It＇s a key of software evolution to achieve available method of software change-trace. A whole traceprocess framework of requirement change is drawn based on three tiers which are propagation ＆ modeling, propagation path, and trace approach of requirement change. Record method about propagation of function-requirement change is addressed based on trace-matrix of change-source ,of change-object and of change component. Implementation of changetrace based matrixcalculation is described, and a simple cost decision method of software change-implementation is brought forward. It is advantage to implement software maintenance as well as software evolution.
