結(jié)論又稱結(jié)束語、結(jié)語。是最終的總體的概括，也可寫建議、對(duì)策、設(shè)想，或提出研究中發(fā)現(xiàn)的尚待解決的問題。它是在理論分析和實(shí)驗(yàn)驗(yàn)證的基礎(chǔ)上，通過嚴(yán)密的邏輯推理而得出的富有創(chuàng)造性、指導(dǎo)性、經(jīng)驗(yàn)性的結(jié)果描述。它又以自身的條理性、明確性、客觀性反映了論文或研究成果的價(jià)值。結(jié)論與引言相呼應(yīng)，同摘要一樣，其作用是便于讀者閱讀和為二次文獻(xiàn)作者提供依據(jù)。結(jié)論又稱結(jié)束語、結(jié)語。是最終的總體的概括，也可寫建16一般來說可以歸納為以下幾點(diǎn)：1、歸納性說明研究結(jié)果或發(fā)現(xiàn)2、結(jié)論性說明結(jié)果的可能原因、機(jī)理或意義3、前瞻性說明未解決的問題一般來說可以歸納為以下幾點(diǎn)：17

有總結(jié)和小結(jié)之分。小結(jié)文稿篇幅短，內(nèi)容少、簡(jiǎn)單，多用于原著論文或短文的正文之后，它只用較少的文字將全文報(bào)告的主要內(nèi)容寫出來。內(nèi)容包括主要的結(jié)果、結(jié)論、數(shù)據(jù)，目的在于闡明本文的成果和理論。

總結(jié)的內(nèi)容和篇幅較小結(jié)為多，多用于綜述或討論類文稿之后，起著概括主題的作用。從內(nèi)容上說需將全文已論述的問題再扼要概括一遍，作者還可以發(fā)表自己的見解和觀點(diǎn)。有總結(jié)和小結(jié)之分。18學(xué)術(shù)英語conclusion結(jié)論的寫作19通常情況下，有關(guān)結(jié)論的內(nèi)容都包括在“結(jié)果與討論”或“討論”中，但有時(shí)也可將“結(jié)論”單獨(dú)列為一節(jié)。在“結(jié)論”中作者應(yīng)清楚、簡(jiǎn)潔地?cái)⑹鲎约貉芯康闹饕J(rèn)識(shí)或論點(diǎn)，其中包括最重要的結(jié)果、結(jié)果的重要蘊(yùn)含、對(duì)結(jié)果的說明或認(rèn)識(shí)等。通常情況下，有關(guān)結(jié)論的內(nèi)容都包括在“結(jié)果與討論”或“討論”中20應(yīng)注意的是，撰寫結(jié)論時(shí)不應(yīng)涉及前文不曾指出的新事實(shí)，也不能在結(jié)論中重復(fù)論文中其他章節(jié)中的句子，或者敘述其他不重要或與自己研究沒有密切聯(lián)系的內(nèi)容，以故意把結(jié)論拉長(zhǎng)。應(yīng)注意的是，撰寫結(jié)論時(shí)不應(yīng)涉及前文不曾指出的新事實(shí)，也不能在21

結(jié)論不是研究結(jié)果的簡(jiǎn)單重復(fù)，而是對(duì)研究結(jié)果更深入一步的認(rèn)識(shí)，是從正文部分的全部?jī)?nèi)容出發(fā)，并涉及引言的部分內(nèi)容，經(jīng)過判斷、歸納、推理等過程，將研究結(jié)果升華成新的總觀點(diǎn)。其內(nèi)容要點(diǎn)如下：

1）本研究結(jié)果說明了什么問題，得出了什么規(guī)律性的東西，解決了什么理論或?qū)嶋H問題；

2）對(duì)前人有關(guān)本問題的看法作了哪些檢驗(yàn)，哪些與本研究結(jié)果一致，哪些不一致，作者做了哪些修正、補(bǔ)充、發(fā)展或否定；

對(duì)于某一篇論文的“結(jié)論”，上述要點(diǎn)1）是必需的，而2）和3）視論文的具體內(nèi)容可以有，也可以沒有；如果不可能導(dǎo)出結(jié)論，也可以沒有結(jié)論而進(jìn)行必要的討論。

結(jié)論段的格式安排可作如下考慮：

如果結(jié)論段的內(nèi)容較多，可以分條來寫，并給以編號(hào)，如1），2），3）等，每條成一段，包括幾句話或1句話；如果結(jié)論段內(nèi)容較少，可以不分條寫，整個(gè)為一段，幾句話。

結(jié)論里應(yīng)包括必要的數(shù)據(jù)，但主要是用文字表達(dá)，一般不再用插圖和表格。3）本研究的不足之處或遺留問題。2316.ConclusionThispaperpresentedtheresultsofinitialresearchintothedevelopmentofmoreeffectiveminesafetyrulesandregulations.Responsesfromalmost500mineworkerswereanalyzedandsomesimpleguidelinesestablished,inparticular,regardingrulecontent.Theycanbesummarizedas:
