在把各个模块集成起来的时候，穿越模块接口的数据是否会丢失；
一个模块的功能是否会对另一个模块的功能产生不利的影响；
各个子功能组合起来，能否达到预期要求的功能的父功能；
全局数据结构是否有问题；
单个模块的误差累积起来，是否会放大，从而达到不能接受的程度。

大恩不言谢！

While integrating every modules, whether the data got across the interface of modules will lose or not;  
Is there any bad influences that one module's function deal with another module's function;
Whether can meet expected requirement of function of father' function while together with every child's function;
Is there any problems about whole data structure;
When each error are cumulated, is it amplified so as not to accept.
