我 们， 这，给的，好的， 吧，
硕士生的论文题目多是从实际的工程问题而来。可能是一个数据采集加控制系统，伴随着EMC的问题。而这些问题的解决往往有软件算法来完成。所以你选择题目的出发点是看看导师在从事哪方面的科研课题，以及这些课题的经费支持情况。在实际问题中找题目来做。并通过在论文过程中，培养自己的科研能力（查找资料、理论分析、实验动手、论文表述），再其次在专业领域提高自己的水平（比如单片机软件编程、FPGA应用等）。
那个（电子商务评论）你可以尝试看下
你这篇中国知网也好，万方数据也好都有例子！甚至百度文库都有！==================论文写作方法===========================论文网上没有免费的，与其花人民币，还不如自己写，万一碰到人的，就不上算了。写作论文的简单方法，首先大概确定自己的选题，然后在网上查找几份类似的文章，通读一遍，对这方面的内容有个大概的了解！参照论文的格式，列出提纲，补充内容，实在不会，把这几份论文综合一下，从每篇论文上复制一部分，组成一篇新的文章！然后把按自己的语言把每一部分换下句式或词，经过换词不换意的办法处理后,网上就查不到了,祝你顺利完成论文!
