Introduction是論文中不可或缺的一部分，作者往往在此陳述研究的主題和背景。本文介紹了Introduction應(yīng)當(dāng)包含的信息，并總結(jié)出SCI論文中該部分的常用句式。

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(guó)外網(wǎng)站，大家可以寫論文的時(shí)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(jiǎn)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(chǎng)所。

Introduction通常占論文總字?jǐn)?shù)的10-15%，例如，如果你的論文總字?jǐn)?shù)是3000，那么你應(yīng)該把Introduction定在400個(gè)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?yàn)樵诳吹秸撐拇缶种?，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(duì)研究的自信心，并用適當(dāng)?shù)膮⒖嘉墨I(xiàn)來支撐你的觀點(diǎn)。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：

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(dòng)機(jī)

6）研究目標(biāo)

7）研究的意義和優(yōu)勢(shì)
