簡(jiǎn)介:貴州大學(xué)2009屆碩士研究生學(xué)位論文碳納米管吸附二噁英的量子化學(xué)理論研究學(xué)科專(zhuān)業(yè)物理化學(xué)研究方向量子化學(xué)導(dǎo)師王一波教授研究生鄒海鳳中國(guó)﹒貴州﹒貴陽(yáng)2009年4月分類(lèi)號(hào)O6413論文編號(hào)2006151068密級(jí)貴州大學(xué)碩士學(xué)位論文摘要1摘要隨著人們環(huán)境保護(hù)意識(shí)的不斷增強(qiáng),二噁英作為一種對(duì)環(huán)境污染極其嚴(yán)重的有機(jī)污染物越來(lái)越引起人們的高度重視。二噁英在工業(yè)生產(chǎn)、日常生活中隨處都可以產(chǎn)生,而且它的污染性很強(qiáng),持續(xù)時(shí)間很久,毒害性很高,對(duì)環(huán)境和動(dòng)植物的破壞性非常強(qiáng)。如何減少二噁英的生成、有效吸附已經(jīng)生成的二噁英將它的污染性控制在盡可能小的范圍內(nèi)成為科研的熱點(diǎn)之一。碳納米管自從90年代被發(fā)現(xiàn)以來(lái),由于其自身的結(jié)構(gòu)特點(diǎn),被廣泛應(yīng)用于諸多領(lǐng)域。既然碳納米管用途廣泛,那這種新型材料能否用來(lái)吸附二噁英呢2001年,RQLONG1等在JACS上發(fā)表文章,報(bào)道了他們用TPDTEMPERATUREPROGRAMMEDDESORPTION方法研究碳納米管與二噁英體系,發(fā)現(xiàn)碳納米管與二噁英之間的相互作用強(qiáng)于活性炭與二噁英間的相互作用;認(rèn)為碳納米管是吸附二噁英的一種非常有效的材料,但二噁英與碳納米管相互作用的大小和本質(zhì)并不清楚。本論文基于RQLONG等的實(shí)驗(yàn)研究工作,運(yùn)用量子化學(xué)方法,對(duì)二噁英與碳納米管相互作用不同取向進(jìn)行了研究,構(gòu)建了PA、PB、TA和TB四種模型,對(duì)模型進(jìn)行了全自由度幾何結(jié)構(gòu)優(yōu)化,并對(duì)部分體系進(jìn)行了能量的分解。全部研究工作使用密度泛函PBE方法,在DZP基組水平下計(jì)算完成。全部研究工作分為兩個(gè)部分第一部分是通過(guò)理論計(jì)算選擇合適的碳納米管模型與二噁英分子;第二部分是對(duì)碳納米管與二噁英分子間相互作用進(jìn)行系統(tǒng)的研究和分析。計(jì)算結(jié)果表明碳納米管與二噁英分子間的相互作用以PB構(gòu)型更穩(wěn)定,其相互作用能為1466KCAL/MOL,大于水分子間氫鍵鍵能的3倍,作用距離為346?。其中,軌道相互作用占了相互作用能ΔEINT的3585﹪,靜電相互作用占了相互作用能ΔEINT的6415﹪。通過(guò)ETS方法揭示了這種相互作用的本質(zhì)靜電相互作用和軌道相互作用共同作用的結(jié)果。本論文擬通過(guò)量子化學(xué)的理論研究,為實(shí)驗(yàn)工作者提供有用的參考信息,為相關(guān)材料的研究與開(kāi)發(fā)提供理論依據(jù)。關(guān)鍵詞關(guān)鍵詞二噁英碳納米管分子間相互作用密度泛函理論

簡(jiǎn)介:超長(zhǎng)彈性細(xì)桿是橫跨生命科學(xué)工程安全等諸多領(lǐng)域的重要的力學(xué)模型它有著極端細(xì)長(zhǎng)性以及小擾動(dòng)即可出現(xiàn)大變形的特性。超長(zhǎng)環(huán)狀DNA在外力和外力矩作用下會(huì)呈現(xiàn)出千差萬(wàn)別的空間構(gòu)型這其中不僅隱含了大量的遺傳信息也蘊(yùn)藏了諸多生命發(fā)展演變過(guò)程的本質(zhì)所以環(huán)狀DNA的研究已經(jīng)成為彈性桿理論研究的一個(gè)重要分支。目前國(guó)內(nèi)外許多研究者都嘗試將經(jīng)典的非線性動(dòng)力學(xué)理論與環(huán)狀DNA構(gòu)型的研究相結(jié)合并取得了一定的研究成果。生物分子學(xué)中DNA拓?fù)浣Y(jié)構(gòu)的變化是各種酶作用的結(jié)果反映到環(huán)狀彈性桿模型上各個(gè)參數(shù)的改變則可以與外力及外力矩等外界因素作用建立起相應(yīng)的關(guān)系。而目前針對(duì)此類(lèi)問(wèn)題的研究都是在簡(jiǎn)化甚至忽略此關(guān)系的條件下進(jìn)行的所以本文運(yùn)用非線性動(dòng)力學(xué)思想考慮多種外界因素影響在現(xiàn)有模型和重新建立的力學(xué)模型基礎(chǔ)上分析了等效初始扭矩等參數(shù)對(duì)圓截面和非對(duì)稱(chēng)截面彈性桿拓?fù)錁?gòu)型的影響并進(jìn)行了數(shù)值分析和對(duì)比驗(yàn)證從數(shù)學(xué)角度考量了外界酶作用與DNA拓?fù)錁?gòu)型變化之間的關(guān)系。本文主要工作及取得的重要結(jié)論主要有以下三個(gè)方面1引入了等效初始扭矩的概念利用勢(shì)能密度函數(shù)與哈密頓函數(shù)形式上的相似性建立了其與系統(tǒng)哈密頓函數(shù)、初始自連接數(shù)之間的定量關(guān)系揭示了非對(duì)稱(chēng)截面環(huán)狀KIRCHHOFF彈性細(xì)桿受到外力矩作用時(shí)其拓?fù)錉顟B(tài)參數(shù)的變化情況。以環(huán)狀DNA分子為背景對(duì)扭矩模型進(jìn)行了非線性動(dòng)力學(xué)分析并利用解析方法中的待定固有頻率法分析了主要參數(shù)對(duì)于扭矩模型穩(wěn)定構(gòu)型的影響。最后利用等效剛度得到相應(yīng)狀態(tài)下曲率的表達(dá)式為進(jìn)一步認(rèn)識(shí)和描述DNA環(huán)受到生物酶作用下的穩(wěn)定構(gòu)型提供了新的理論途徑2為研究復(fù)雜情況下的圓截面KIRCHHOFF細(xì)桿的構(gòu)型特征在原有的以復(fù)曲率為未知變量的SCHRDINGER方程建立了以扭率分量為變量的二自由度平衡方程。運(yùn)用動(dòng)力學(xué)中內(nèi)共振的思想指出了彈性桿出現(xiàn)諸多復(fù)雜構(gòu)型的原因在于兩個(gè)自由度固有頻率之比的不確定性該比值的取值區(qū)間為00531當(dāng)桿發(fā)生面內(nèi)變形時(shí)對(duì)應(yīng)的是01內(nèi)共振的情況。3連接數(shù)的計(jì)算是彈性桿拓?fù)鋵W(xué)研究的重要環(huán)節(jié)本文利用彈性桿的本構(gòu)關(guān)系及DARBOUX矢量角關(guān)系對(duì)計(jì)算連接數(shù)的GAUSS積分進(jìn)行了有效簡(jiǎn)化簡(jiǎn)化所得結(jié)果表明GAUSS積分可以寫(xiě)成僅含曲率與撓率函數(shù)的形式無(wú)需切線、矢徑函數(shù)等復(fù)雜函數(shù)即可直接計(jì)算彈性桿自連接數(shù)從而增強(qiáng)了其實(shí)用性。

簡(jiǎn)介:還原論是哲學(xué)史上有深遠(yuǎn)影響的主張和派別。近四十年來(lái),由于非物理學(xué)哲學(xué)的興起,反還原論調(diào)變?yōu)榭茖W(xué)哲學(xué)的主流聲音。本論文基于化學(xué)概念分析,對(duì)化學(xué)理論做初步的特征性認(rèn)識(shí),嘗試對(duì)化學(xué)還原論給予客觀如實(shí)的評(píng)價(jià)。本論文主要從兩方面的內(nèi)容展開(kāi)討論。一是針對(duì)化學(xué)還原論,通過(guò)策略性選擇,避免繼續(xù)糾纏于量子化學(xué)的近似計(jì)算問(wèn)題,對(duì)化學(xué)中的元素概念和分子結(jié)構(gòu)概念的發(fā)展歷程進(jìn)行細(xì)致入微的分析,考察化學(xué)概念和理論的特征二是系統(tǒng)梳理還原論的思想淵源、起因,對(duì)物理主義層次性結(jié)構(gòu)基礎(chǔ)上提出的各種代表性還原模型,理論還原的中心主張有清晰的梳理和把握,結(jié)合化學(xué)概念和理論特征揭示還原論存在的局限。本論文包括引言和五章節(jié)的研究討論內(nèi)容。引言部分簡(jiǎn)單考察化學(xué)哲學(xué)研究狀況與化學(xué)還原問(wèn)題的相關(guān)性,以及國(guó)內(nèi)外對(duì)化學(xué)還原問(wèn)題的研究狀況和視角,在此基礎(chǔ)上介紹本論文的研究思路和研究?jī)r(jià)值。第一章中系統(tǒng)梳理還原論的根源和理論基礎(chǔ),并結(jié)合化學(xué)哲學(xué)的發(fā)展簡(jiǎn)要介紹相關(guān)的化學(xué)還原論題。作為哲學(xué)教條或宗旨的還原論的產(chǎn)生,首先根源于追求科學(xué)統(tǒng)一的哲學(xué)理想。其次是世界的層次結(jié)構(gòu)主張,以及與此相關(guān)形成的微觀物理主義觀點(diǎn),分析論證微觀物理主義存在的致命問(wèn)題。在第二章分析科學(xué)哲學(xué)中主張的適于所有科學(xué)還原的三種理論還原模型,指出這三種模型針對(duì)化學(xué)科學(xué)存在的困難和不足。第三章和第四章立足于化學(xué)中的兩個(gè)基本概念化學(xué)元素和分子結(jié)構(gòu),通過(guò)考察概念發(fā)展史,突出表現(xiàn)化學(xué)理論的語(yǔ)境依賴(lài)性特征,揭示化學(xué)科學(xué)中認(rèn)識(shí)論還原存在的問(wèn)題和困難。第五章是論文的結(jié)論。化學(xué)理論與物理學(xué)第一原理之間的關(guān)系,根本的問(wèn)題不在于近似,對(duì)理論還原的研究應(yīng)當(dāng)立足于更深層次的問(wèn)題和視角。從元素概念和分子概念的提出和相關(guān)理論的形成來(lái)看,深層次基本實(shí)體概念的提出本身與還原的內(nèi)涵一致,還原方法的應(yīng)用和追求是相當(dāng)富有成效的,還原論對(duì)于一門(mén)學(xué)科的發(fā)展有著非常重要的意義。但是,關(guān)于深層次微觀不可觀測(cè)實(shí)體描述的語(yǔ)境依賴(lài)性又決定了理論的整體性特征,依賴(lài)于語(yǔ)境的科學(xué)理論必然是不可還原的。因而,關(guān)于化學(xué)理論的結(jié)構(gòu)認(rèn)識(shí)有必要在兩者之間保持必要的張力。

簡(jiǎn)介:經(jīng)典的第一積分能否作為約束是一個(gè)存在爭(zhēng)議和令人困擾的問(wèn)題,至今仍沒(méi)有定論。為了解決這個(gè)問(wèn)題,本論文深入研究了約束和經(jīng)典第一積分經(jīng)典第一積分在本文是指循環(huán)積分和能量積分的內(nèi)在聯(lián)系,證明約束和經(jīng)典第一積分從本質(zhì)上都屬于第一積分的范疇。進(jìn)一步,本論文在第一類(lèi)拉格朗日方程的基礎(chǔ)上證明了所有除約束外的第一積分包括經(jīng)典第一積分都可以按約束處理,而相應(yīng)的拉格朗日乘子等于零。本論文還利用系統(tǒng)的全部第一積分對(duì)動(dòng)力學(xué)方程進(jìn)行降階,并得到動(dòng)能嵌入形式的動(dòng)力學(xué)方程。為了揭示能夠把第一積分看作約束處理的本質(zhì)原因,本論文綜合考慮牛頓的經(jīng)典力學(xué)和拉格朗日的分析力學(xué),把微分形式的分析力學(xué)變分原理的適用范圍從約束組所限制的微變空間擴(kuò)展到積分組上的微變空間,并且成功的把物理規(guī)律的普遍性歸結(jié)為微變空間上對(duì)應(yīng)變分的獨(dú)立性。進(jìn)一步,根據(jù)改進(jìn)的多重微變空間上的變分原理以及改進(jìn)微變空間上對(duì)應(yīng)變分的獨(dú)立性發(fā)展了拉格朗日力學(xué)體系,并推廣到事件空間。改進(jìn)后的理論體系不僅從根源上解決了第一積分能否作約束處理這個(gè)爭(zhēng)議問(wèn)題,而且該理論體系與牛頓第二定律一致。本論文研究了最大可積組與系統(tǒng)的解析解之間的關(guān)系,并利用最大可積組得到一類(lèi)兩連桿、三連桿以及四連桿平面自由運(yùn)動(dòng)的周期性解析解;還根據(jù)可積組與系統(tǒng)的運(yùn)動(dòng)軌跡的關(guān)系,計(jì)算了零耦合自由飄浮空間機(jī)械臂的軌跡方程。進(jìn)一步,在改進(jìn)的微變空間動(dòng)力學(xué)理論和經(jīng)典的降階方法基礎(chǔ)上,提出了混合降階方法首先利用系統(tǒng)的最大可積組建立初步的降階模型,然后再根據(jù)羅斯方程和惠特克方程分別對(duì)循環(huán)積分和能量積分進(jìn)行進(jìn)一步降階。在多重微變空間動(dòng)力學(xué)建模方法的基礎(chǔ)上,利用一般三體系統(tǒng)所共有的經(jīng)典第一積分和中心構(gòu)形的平面三體系統(tǒng)所特有的第一積分降階系統(tǒng)的動(dòng)力學(xué)方程,得到與系統(tǒng)的解等價(jià)的可積組,從而證明了中心構(gòu)形的平面三體問(wèn)題都具有周期解。本論文構(gòu)造了一類(lèi)對(duì)稱(chēng)的三體系統(tǒng),此類(lèi)系統(tǒng)中有一個(gè)質(zhì)點(diǎn)作往復(fù)直線運(yùn)動(dòng),另外的兩個(gè)質(zhì)點(diǎn)等質(zhì)量且關(guān)于第一個(gè)質(zhì)點(diǎn)往復(fù)運(yùn)動(dòng)所形成的直線旋轉(zhuǎn)180度對(duì)稱(chēng),并且該系統(tǒng)滿(mǎn)足一定的初始條件。此類(lèi)系統(tǒng)共有14個(gè)獨(dú)立的第一積分,容易證明只要再找出一個(gè)獨(dú)立的可積的第一積分,則系統(tǒng)的解就是周期解。進(jìn)一步,證明了此類(lèi)系統(tǒng)所對(duì)應(yīng)的曲線族中可以找到其中一條曲線,該曲線對(duì)應(yīng)的解為周期解。本論文還證明了這類(lèi)三體系統(tǒng)的兩個(gè)旋轉(zhuǎn)質(zhì)點(diǎn)的運(yùn)動(dòng)曲線不能保持在某個(gè)平面內(nèi)。
