本文主要總結(jié)SCI論文 Introduction部分的常用句式,，總結(jié)內(nèi)容來自國外網(wǎng)站（避免和國內(nèi)資源重復(fù)）,，大家可以寫論文的時候,，直接從中挑選使用,！值得收藏！

Introduction部分在Abstract之后出現(xiàn),。Introduction部分應(yīng)向讀者簡要概述你的主題和研究的原因,。Introduction是設(shè)置研究背景和給讀者留下良好第一印象的最好場所。Introduction通常占論文總字數(shù)的10-15%,，例如,，如果你的論文總字數(shù)是3000，那么你應(yīng)該把Introduction定在400個字左右,。通常建議在完成論文的其他部分后編寫論文的Introduction部分,。這是因為在看到論文大局之前，很難弄清楚在論文的Introduction部分到底要放什么內(nèi)容,。Introduction部分應(yīng)該讓讀者感覺到你對研究的自信心,，并用適當(dāng)?shù)膮⒖嘉墨I來支撐你的觀點。閱讀Introduction部分后,，讀者必須清楚地了解研究論文的其余部分要做什么,。

研究論文的Introduction部分應(yīng)包括以下內(nèi)容：

（1）總體介紹

（2）問題定義

（3）研究現(xiàn)狀

（4）問題解決方案

（5）研究動機
