【摘 要】 簡.奧斯汀是18世紀(jì)末杰出的英國女小說家，同時也是英國文學(xué)史上第一個重要的女作家。在奧斯汀的作品中，“理性”與“情感”是一個永恒的、矛盾統(tǒng)一的主題。本文對照其早期和后期的主要作品《傲慢與偏見》和《勸導(dǎo)》，對作品中女性人物的進行分析，看奧斯汀作品中“理性”與“情感”的平衡。

引言部分對簡〃奧斯汀在英國文學(xué)史的影響以及她的作品做了簡單的回顧，并指出了論文的主題。第二部分討論了“理性”與“情感”在《傲慢與偏見》中的體現(xiàn)。通過分析夏洛蒂〃盧卡斯、簡〃班內(nèi)特、伊麗莎白〃班內(nèi)特三個女性人物點明在簡〃奧斯汀的前期作品中，女主人公只有用“理性”約束“情感”，才能獲得婚姻的幸福。第三部分討論了“理性”與“情感”在《勸導(dǎo)》中的體現(xiàn)并指出“理性”只能帶來痛苦并不能給將來任何保障。這表明了“理性”向“情感”的轉(zhuǎn)變并歌頌了情感的偉大力量。在第四部分中，具體地解釋了簡〃奧斯汀創(chuàng)作思想的改變。并主要從社會和簡〃奧斯汀的個人經(jīng)歷兩方面闡述了這一改變的原因。

簡〃奧斯汀是一個集大成者，具有里程碑的意義，在英國文學(xué)史上起到了承上啟下的作用。奧斯汀闡述了自我認識的重要性并解決了這樣的疑惑，那就是只有當(dāng)“理性”與 “情感”達到平衡時，才會得到真正的幸福。

摘要：

19世紀(jì)俄國“自然派”作家正式提出了寫“小人物”的口號。他們在作品中描述小人物的悲慘命運和內(nèi)心痛苦，從而使文藝成為“社會的一面忠實的鏡子”?！靶∪宋铩痹谏鐣泄匐A、地位極其低下，生活困苦，但又逆來順受、安分守己、性格懦弱、膽小怕事，因此成為“大人物”統(tǒng)治下被侮辱的犧牲者。但通過對作家普希金、果戈理、契訶夫、陀斯托耶夫斯基等關(guān)于小人物的作品及其主人公的分析，我們不難發(fā)現(xiàn)“小人物”的悲劇命運并非僅限于官僚統(tǒng)治欺凌等外在的社會原因，同時還有“小人物”自身固有的內(nèi)在原因，其中，因循守舊不思轉(zhuǎn)變觀念的思維模式是釀成“小人物”悲劇命運的思想原因，軟弱怯懦、不思反抗的逃避行為是釀成“小人物”悲劇命運的性格原因。作者再現(xiàn)“小人物”保守思想和懦弱性格的目的，在于通過對“小人物”靈魂的拷問，完成人格形態(tài)的批判，把他們從沉睡中喚醒。對“小人物”寄寓有限的同情，但更多地傾注了對其劣根性哀其不幸，怒其不爭的抨擊。揭示現(xiàn)實中小人物存在的具體現(xiàn)象，生活在現(xiàn)代社會的人們，應(yīng)該靜下心來反思一下，是不是自己身上也能找到小人物的影子，指出文章對現(xiàn)實的警示意義。

(Chinese Department，Yulin College，Yulin，Shaanxi719000)

Abstract：In 19th century the writer of ＂the natural faction＂in Russia proposed a slogan to write the life of ＂the no man＂．They described the tragic destiny and inner world pain of ＂the no man＂，and it made the literary arts to become ＂a faithful mirror of the society＂．These ＂no man＂had a low position in the society and lead a miserable life，but at the same time，they all content with things as they are and had cowardly charcuter，therefore，they became the prey who were insulted under the domination of＂the great man＂．However，according to the author＇s analyze on the work which were wrote by Pushkin，Nikolai Vasilievich Gogol，Anton Chekhov and Fyodor Mikhailovich Dostoevsky，we can easily find the reason of tragic destiny of the＂no man＂is not only some external causes but also some internal causes．Among all this reasons，the thought pattern of stick to old ways is their tragic destiny＇s thought reason．The author reproduce their conservative thinking and cowardly character in order to crieicize the personality from of the＂no man＂and awake them from deep sleep．In this thesis，the author gives the no man limited sympathy，but pay more attention to attack their sadness and not the behaviors of struggle for their angry．According to reveal the phenomanon of existence of＂no man＂in real life，the author hopes the people live in real life can introspect thenselves and shows the significance to the reality．

論文題目：單壁碳納米管的AFM操縱、形變及相關(guān)拉曼光譜研究

作者簡介：段小潔，女，1980年2月出生，2002年9月師從于北京大學(xué)劉忠范教授，于2007年7月獲博士學(xué)位。

中文摘要

對形變碳納米管（CNTs）的研究，包括研究其在應(yīng)力存在下的結(jié)構(gòu)演化、應(yīng)力對其各種光電性質(zhì)及電子能帶結(jié)構(gòu)的影響等，不僅對CNTs在復(fù)合材料、納電子和納機電器件、以及應(yīng)力傳感器等中的應(yīng)用具有重要意義，還對相關(guān)理論的發(fā)展有巨大推動作用。本論文發(fā)展了對表面上單壁碳納米管（SWNTs）的原子力顯微術(shù)（AFM）可控操縱方法，基于此AFM可控操縱，研究了CNTs在彎曲形變下的屈曲行為，以及SWNTs在扭轉(zhuǎn)和拉伸兩種形變下的共振Raman光譜特征。主要成果包括：

1.發(fā)展了對表面上SWNT的AFM可控操縱方法；

通過對操縱過程中針尖運動路徑的合理設(shè)置、SWNT上操縱位置和針尖下壓距離的選擇，可以向SWNT中引入各種類型的應(yīng)力。SWNT中產(chǎn)生的應(yīng)力由其和基底間的相互作用力保持。發(fā)展了基于Si的AFM氧化的SWNT納米焊接術(shù)，以增加AFM操縱的可控性。當(dāng)對表面有SWNT的基底Si進行AFM氧化時，新生成的SiOx會對SWNT進行包覆，從而可以將SWNT在氧化點有

效的固定到基底表面。而且SWNT的存在會對Si基底的AFM氧化有明顯的增強作用，相同條件下，表面有SWNT的Si氧化后產(chǎn)生的SiOx，比沒有SWNT時更多，這種增強作用有利于對

SWNT的焊接固定。焊接的強度可以通過改變氧化偏壓、針尖運動速率（氧化時間）等進行調(diào)節(jié)，提高氧化偏壓、降低針尖移動速率有利于增強納米焊接的強度?？諝庵袩嵫趸瘜嶒灪屠庾V的表征均證明，此焊接過程對SWNT的化學(xué)結(jié)構(gòu)無明顯影響。在某些點對SWNT進行焊接固定后，AFM操縱引入的形變的大小和分布可以被有效地控制，從而大大增加AFM操縱的可控性。

采用更強的AFM氧化條件，可以實現(xiàn)SWNT和Si的同時氧化，從而可以在任意位點對SWNT進行切割。結(jié)合AFM納米切割、焊接和操縱等操作，可以構(gòu)筑各種復(fù)雜形狀的SWNTs，體現(xiàn)

了AFM作為納米工具箱的作用。

2.研究了CNTs在彎曲形變下的屈曲行為；

通過選擇合適的操縱位點、被操縱的CNT片段長度、操縱路徑并優(yōu)化針尖下壓距離，可以嚴(yán)格控制彎曲CNT的角度，這樣通過AFM操縱對同一CNT的可控彎曲，獲得了一系列彎曲角度逐漸增大的CNT。CNT被操縱以后，與基底相互作用力會有明顯減小，這使得CNT的有效彎曲區(qū)域，位于與基底只有vdW相互作用的被操縱部分，在AFM表征下表現(xiàn)為固定部分和被操縱部分的交點。有效彎曲部分與基底間僅有vdW相互作用，其長度在整個彎曲過程中幾乎保持不變。

通過記錄彎曲“點”在彎曲角度逐漸增大過程中的高度變化，研究了CNTs在彎曲形變下的結(jié)構(gòu)演化和屈曲行為。發(fā)現(xiàn)不同CNTs在彎曲過程中，表現(xiàn)出“突變”和“漸變”兩種屈曲模式，分別對應(yīng)于彎曲“點”高度的突躍、均勻彎曲向屈曲結(jié)構(gòu)的直接轉(zhuǎn)化，和彎曲“點”高度的逐漸增大、均勻彎曲向屈曲結(jié)構(gòu)的逐漸轉(zhuǎn)化。“漸變”屈曲導(dǎo)致一系列屈曲過渡態(tài)的出現(xiàn)。“突變”多發(fā)生于小直徑管，而“漸變”更常見于大直徑管。通過對CNTs的層數(shù)和厚度等的估算，發(fā)現(xiàn)一般情況下，“漸變”屈曲模式的CNTs比“突變”模式的CNTs具有更大的厚度直徑比。對“突變”屈曲模式的CNTs，臨界屈曲角度隨CNTs直徑的增大而減小。

分子動力學(xué)模擬發(fā)現(xiàn)，（1）所研究的CNTs中，SWNTs均為“突變”屈曲模式，而雙壁和三壁管均采取“漸變”屈曲模式；（2）“漸變”屈曲過程對應(yīng)彎曲角度逐漸增大時，多壁管從最外層到最內(nèi)層的逐漸屈曲，和各管層屈曲程度的逐漸增加，這是由其多層結(jié)構(gòu)導(dǎo)致的各層壁屈曲行為的不同步，和管壁間vdW相互作用對屈曲的阻礙造成的，這說明MWNTs的多層結(jié)構(gòu)是導(dǎo)致其“漸變”屈曲的主要原因；（3）基底的vdW相互作用對CNTs的屈曲行為沒有明顯影響。從導(dǎo)致兩種屈曲模式的機理考慮，除直徑外，CNTs的層數(shù)對其屈曲行為也有重要影響，這預(yù)示了在CNTs的力學(xué)性質(zhì)中，存在不同于傳統(tǒng)尺寸效應(yīng)的雙尺寸效應(yīng)，即直徑和層數(shù)共同決定CNTs力學(xué)行為。

本工作利用AFM可控操縱，在實驗上幾乎全程觀察了CNTs在彎曲過程中的結(jié)構(gòu)演化和屈曲形成過程，其所揭示的兩種屈曲模式的形成規(guī)律，不僅對大量存在的CNTs形變的理論工作提供了支持和參考，一定程度上填補了實驗上的空白，還對CNTs在復(fù)合材料、納電子和納機電器件、以及應(yīng)力傳感器等中的應(yīng)用具有重要意義，3.研究了扭轉(zhuǎn)和拉伸形變下單根SWNTs的共振Raman光譜行為；

AFM操縱可以向超長SWNT中同時引入扭轉(zhuǎn)和拉伸應(yīng)力，由于拉伸形變比扭轉(zhuǎn)形變的傳輸距離更遠，在操縱點附近扭轉(zhuǎn)和拉伸兩種形變同時存在，距離操縱點較遠的區(qū)域，只有純拉

伸形變存在。扭轉(zhuǎn)形變的產(chǎn)生證明了SWNT在AFM操縱下滾動的發(fā)生。

扭轉(zhuǎn)和拉伸形變都會導(dǎo)致SWNTs拉曼模振動頻率的變化。研究發(fā)現(xiàn)：（1）扭轉(zhuǎn)形變下，?RBM變大，位于～1600 cm-1的G+(E2(g))模振動頻率發(fā)生較大的紅移，而其他在1590 cm-1～1560

cm-1范圍內(nèi)的大部分G模會發(fā)生輕微的藍移，振動頻率發(fā)生紅移的G模的位移量，一般遠遠大于發(fā)生藍移的G模的位移量；（2）拉伸形變下，RBM和G+(E2(g))模振動頻率不變，而在1590 cm-1～

1560 cm-1范圍內(nèi)的大部分G模會發(fā)生明顯的紅移。（3）不同Raman活性模對形變的敏感度不同，扭轉(zhuǎn)形變下，RBM、位于～1600 cm-1的G+(E2(g))模比其他G模更敏感，而在拉伸形變下，其他G模卻具有更高的敏感度。這與形變導(dǎo)致的發(fā)生變化的C-C鍵是否與各模的原子位移模式相關(guān)聯(lián)有關(guān)；（4）通過對SWNTs中形變量大小和Raman頻率對形變變化率d?/d?地計算，發(fā)現(xiàn)RBM振動頻率對扭轉(zhuǎn)形變的變化率d?(RBM)/d?t，隨SWNTs手性角的增大幾乎線性增大。

某些SWNTs中，扭轉(zhuǎn)形變導(dǎo)致的對稱性破缺還會導(dǎo)致Raman模的分裂或新模的出現(xiàn)。按照預(yù)測，這種分裂或新模的出現(xiàn)最可能發(fā)生在鋸齒形和椅形SWNTs中。扭轉(zhuǎn)和拉伸形變都會導(dǎo)致SWNTs共振拉曼振動模強度的變化，這體現(xiàn)了形變對SWNTs電子躍遷能Eii的影響。根據(jù)

AFM Manipulation, Deformation and Related Raman Spectroscopy of

Single-Wall Carbon Nanotubes

Duan Xiaojie

ABSTRACT

The study on deformed carbon nanotubes(CNTs), including the study of their structure evolution and properties change under strain, is important not only for the application of CNTs in composite materials, strain sensors, nanoelectronic and nanoelectromechanical devices, but also for the development of related theory.In this thesis, we have developed controlled atomic force microscopy(AFM)manipulation techniques for single-wall carbon nanotubes(SWNTs)on surfaces.Using this controlled AFM manipulation, the buckling behavior of CNTs under bending, and resonance Raman spectroscopy of SWNTs under torsional and uniaxial strains, have been studied.The main results are listed as followings:

1.Controlled AFM manipulation techniques for SWNTs on surfaces have been developed By defining proper tip path, manipulation position on SWNT, and choosing optimal tip pressing distance, different kinds of deformation can be induced into SWNT.The deformation is stabilized by the interaction between SWNTs and substrate.To get controlled AFM manipulation, a new kind of nanofabrication---nano-welding has been invented based on the AFM oxidation of Si substrate.When the Si substrate with SWNT on top of it is oxidized by the AFM tip, the newly formed SiOx will grow around the tube, effectively fixing that site of SWNT onto the Si substrate.The existence of SWNT can enhance the oxidation of Si.With same oxidation condition, more SiOx can be produced with the presence of SWNT than the case where there is no SWNT.This is helpful for the fixing.The intensity of the welding can be modulated by changing the oxidation voltage and the tip moving speed.With higher voltage and slower tip moving, stronger welding can be obtained.From the thermal oxidation of SWNTs in air and the Raman characterization, it was found that this nano-welding has no obvious influence on the chemical structure of SWNTs.Together with this nano-welding, the magnitude and distribution of strain induced into SWNT by AFM manipulation can be well controlled.Both SWNT and Si can be oxidized when using stronger oxidation condition(much higher voltage and lower tip moving speed), thus the SWNT can be cut at well defined position.Combining this AFM cutting, nano-welding and manipulation, complex SWNT-based structures can be constructed, proved the function of AFM as a nano-toolbox.2.The buckling behavior of CNTs under bending has been studied

By choosing proper manipulation site on SWNT, the length of the fragment which is being manipulated, manipulation path, and optimal tip pressing distance, the angle can be well controlled when SWNT is bent by AFM manipulation.Based on this controlled bent of CNT by AFM manipulation, A CNT with a series of different bending angles has been obtained.The interaction between manipulated SWNT fragment and substrate is largely decreased after the manipulation.And the effective bending region is located at the fragment where Only vdW interaction exists between it and the substrate.It appears as the cross point between the fixed SWNT part and

manipulated SWNT part in the AFM image.Only vdW force exists between the effective bending region and substrate, and its length keeps constant when changing the bending angle.Through recording the height change at the effective bending region when changing the bending angle gradually, The structural evolution and buckling behavior has been investigated under the bending.Two distinct ?abrupt? and ?gradual? buckling modes have been revealed in different CNTs.For the ?abrupt? buckling mode, the height of the bending ?point? has a sudden increase, and an abrupt transition from the uniform bending to buckling happens.While the ?gradual? mode corresponds to a gradual increase of the height at the bending ?point?, with a gradual transition from uniform bending to buckling.The ?gradual? buckling results in a series of buckling intermediate formation.?Abrupt? buckling mode is mostly found for small diameter CNTs, while for large diameter CNTs, the ?gradual? mode is more common.Through the estimation of the wall numbers and thickness of CNTs, it was found that the CNTs with ?abrupt? buckling mode has smaller thickness diameter ratio than the CNTs with ?gradual? buckling mode.The critical buckling angle decreases with the increase of CNT diameter for the ?abrupt? buckling mode.The buckling behavior has also been investigated by molecular dynamics(MD)simulations.It was found:(1)for all the CNTs studied, the SWNTs have “abrupt” buckling mode, and double and three walled CNTs take “gradual” buckling modes;(2)the “gradual” buckling corresponded to the process that different tube walls of MWNTs buckled at different bending stages, and the buckling degree of individual tube walls gradually increased along with the bending strain increase.This is caused by the unsynchronization of the buckling for different walls caused by the multi-shell character, and the retarding of buckling by the inter-wall vdW force.The study on the formation of the two buckling modes found that the multi-shell structure of MWNTs accounts for the “gradual” buckling modes;(3)The MD studies also proved that the vdW interaction with substrate has no remarkable effect on CNTs buckling behavior.The study on the buckling mechanism suggests that except for the diameter, the wall number also determines the buckling behavior.This means for the mechanical properties of CNTs, a special “dual-size” effect may exists, that is, both the size and the thickness determine the CNTs mechanical behavior.By using controlled AFM manipulation, the work here observed the structural evolution and buckling formation almost in the whole bending process.The founding about the two buckling modes, not only provides support and reference for the relevant theoretical study, fills the gap between theory and experiment, but also is important for the application of CNTs in composite materials, nanoelectronics and NEMs, and strain sensors.3.The resonance Raman spectroscopy of individual SWNTs under torsional and uniaxial

strain has been investigated

The AFM manipulation can induce both torsional and uniaxial strains into the ultra-long straight SWNTs.Because the longer propagation distance of uniaxial strain than the torsional strain, only pure uniaxial strain exists at region far from the manipulation point.While at region close to the manipulation sites, both the two strains happen.The formation of torsional strain suggested the rolling of SWNT under the present AFM manipulation.Both uniaxial and torsional strain can change the Raman vibrational frequency.It was found that:

(1)the RBM and G-band spectra responded differently to the two types of strains.Under torsional strain, RBM frequency ?RBM was found to upshift and one of the modes assigned to E2 symmetry in the G+ band, which occurs at ~1600 cm-1(G+(E2(g))), downshifted significantly, whereas the rest G

modes located in the range of 1590 cm-1～1560 cm-1 are slightly upshifted.The redshift of the(G+(E2(g)), ismuch larger that the buleshift of other G modes;(2)Under uniaxial strain, ?RBM and ?G+(E2(g))do not have noticeable response and the rest of the G modes in the range of 1590 cm-1～1560 cm-1 are downshifted.(3)Different Raman modes have different sensitivity to both strains.RBM and G+(E2(g))is more sensitive to torsion than other G modes.Whereas under uniaxial strain, other G modes have larger sensitivity than RBM and G+(E2(g)).This is related to the correlation between the C-C bond change and the atom vibrational displacement of different modes;(4)The

calculation on the strain magnitude and frequency shift of Raman modes per strains d?/d? found that, under torsional strain, d?(RBM)/d?t nearly linearly increased along with the increase of the tube chirality angle.G-band was found to split into multiple sub-bands in some cases, presumably due to broken symmetry induced by torsion.This splitting is most likely found in zig-zag and armchair SWNTs.Both the uniaxial and torsional strains can change the intensity of resonant Raman peaks.This is originated from the influence of strains on electronic tranision energy Eii.From this change, the

modulation direction and magnitude of strains on the electronic transition energy of SWNTs can be calculated.The influence of strain on the resonant Raman spectra of SWNTs has drawn much attention recently.The work here firstly experimentally studied the torsional strain effect on resonant Raman spectra of SWNTs.And the study in the single SWNT scale by AFM manipulation can exclude the average effect originated from different diameter and chiraligy.This helps to reveal the intrinsic property of SWNts.The comparison of uniaxial and torsional strain for same SWNT, also benefit the understanding of the influence of different strains on SWNTs.4.The analysis and modulation of strain distribution along SWNTs axis, and the comparison

of related mechanical parameters of different SWNTs

It was found that after AFM manipulation, both the torsional and uniaxial strain would have a “?” shaped distribution along the SWNT axis, due to the friction between SWNTs and the substrate, and the partial relaxation of strain.The characteristics of the distribution, including the propagation distance of strain, the maximum strain and its position, and the slope of the strain distribution, are determined by the force exerted on SWNT by AFM tip, the elasticity modulus E and the shear modulus G, and the friction between SWNT and surface.By controlling the AFM manipulation and using patterned substrate with different components, the magnitude and distribution of strain in SWNT has been modulated.With the comparison of strain distribution in different SWNTs, their mechanical properties, such as E and G, and the friction with the substrate have been compared, on the single SWNTs scale.It was found that there is no monomial relationship between these parameters and the SWNTs diameter, this suggests that the chirality of SWNTs also has important effect on SWNTs mechanical properties.Key words:Single-Walled Carbon Nanotubes(SWNTs), AFM manipulation and fabrication, deformation(strain), buckling, resonance Raman spectroscopy
