翻译下面这一段
随着无线通信技术的不断发展,无线物理层的安全问题越来越被大家所关注.而窃听信道的研究是无线通信的物理层安全的重要研究思路,因此有着十分重要的研究价值.本文介绍了窃听信道的基本概念和定理,并在此基础上分类讨论了几种不同类型的窃听信道及它们的基本编码方式.并根据所学的关于BSC窃听信道的知识,建立一个三次交替通信的窃听信道的模型,研究其基本编码方式.这样的窃听信道较于一次交替通信的窃听信道,可以在窃听者信道的噪声很小的情况下,依然保证通信的安全.

答案和解析
along with the development of wireless communicating technology,the safety factors on wireless physical technology is focused by public at a higher level than before.As the researching on wiretapping channel is a very important branch of the physical safety researching of wireless comunicating technology,it is very valuable to research the wiretap channel technology.The following passage had intrudoced the basic concepts and principles of wiretap channel and also had discussed different types of wiretap channels along with their basic encoding methods.According to the knowledges relative to BSC wiretap channel,a model of 3-way alternative communication was built to research the basic encoding method.This kind of wirepat channel could ensure the safety of the communication with a wiretapping channel under a low noise situation compared with a 1-way alternative communication channel.
