在report中， executive summary 和introduction 有什么区别

executive summary是对整篇report的总结，主要写你的研究内容，研究对象，研究目的，研究意义等等，introduction部分相当于一个background ，而不是概括report的内容

答案：executive summary：执行总结，意思是将上文中的内容进行简单的，可执行性的概括。introduction：简介，意思是对本文的内容和背景进行简单的介绍，以引出后文。
详细解释：
举个例子说明，一般写一个business proposal（商业提案）的时候，introduction只是简单介绍一下将要推出的产品或服务是干什么的；而executive summary要把business plan（商业计划）中的每一个模块都要简单概括一下，尤其是financial projections（财务预算）.

executive summary：执行摘要 introduction：课题研究简介，开场白
