建筑的检测，检测防火等级，逃生路线，以及楼宇的用途，等等。-Building testing, test fire rating, escape routes, as well as the use of buildings, and so on.

建立迷宫模型，采用c++进行编程，仿真界面显示迷宫和最快逃生路线。(The maze model is established, and the c++ is used to program. The maze and the fastest escape route are displayed in the simulation interface.)
