此代码为RFID中防冲突算法固定帧ALOHA算法法中的，时隙中的平均标签数目e随帧的大小而变化的仿真 -This code for the simulation of the time slot, the anti-collision algorithm in RFID fixed frame ALOHA algorithm method, the average number of tags e varies with the size of the frame

此代码为RFID中防冲突算法中动态帧ALOHHA算法的仿真，运用时隙中标签平均数的期望值e。 -This code for RFID anti-conflict algorithm to dynamically frame ALOHHA algorithm simulation, use the slot label average expectations e.

时隙 ALOHA（Slotted ALOHA）算法是在纯ALOHA 算的基础上将时间分成了多个离散的时隙，被分割成的时隙的长度要大于标签所携带数据信息帧的长度-Slot ALOHA (Slotted ALOHA) algorithm is based on pure ALOHA time will be counted into the slot more discrete, divided into the slot length is greater than the length of t
