英语翻译
原文是 ：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.
我自己的翻译：
With the continuous development of wireless communication technology,The security issues of wireless physical layer has been concerned by more and more people.The wiretap channel is one of the ideas of researching security issues on wireless physical layer of wireless communication.So it has a very important value for researching.This article describes the basic concepts and theorems of the wiretap channel,Discussed several different kinds of wiretap channel and their basic coding Method.And based on what we have learned about BSC wiretap channel,to establish a third alternate communication wiretap channel model,and study the basic encoding method.Compared with the one alternate communication wiretap channel,it can ensure secure communications even in the case that eavesdropper’s channel is noiseless.
大神们帮我看看哪些地方有语法错误或者翻译的不合适.

Answer 1

第一行The security 改为 the security  逗号后面字母小写
第三行researching 也可改为investigating
第三行末,so 也可改为Therefore,
第四行 it has a very significant research value
第四行 This paper introduces the basic concepts and theorems of the wiretap channel, on the base of which several different kinds of wiretap channels and their basic coding methods are discussed. Moreover, according to the knowledge that we have learned about BSC wiretap channel, a three-time alternate communication wiretap channel model is established and its basic encoding method is studied as well. Compare with the one alternate communication wiretap channel, it can ensure the communication security even in the case that the noise in eavesdropper's channel is tiny little.
