NS2中的模拟场景脚本自动生成工具，非常方便

移动电话主要采用频率复用，但分配给移动电话的频段很少，远不能满足用户的需要。 因此就提出将地区划分成小区，称为蜂窝（Cell），每个蜂窝内使用一组频率，相隔一段距离后，相同的频率又可重复使用。 -The main use of mobile phone frequency reuse, but allocated to the small-band mobile phone, far from being able to meet the needs of users. Therefore proposed to be divided into residential areas, known as cellular (Cell), each use a set of cellular frequencies, separated by some distance, the same frequency can be reused.

这个程序可以根据系统的时钟，通过多个计数器的联合使用可以完成秒脉冲信号的产生，并同时输出对应的时分秒信息。-it can generate the second_pulse.and output the time information of the second_pulse

使用DELPHI进行串口通信软件的编辑，使用的控件是MSComm，可以实现串口号、波特率、校验位、停止位、通信方式等的选择。
