武漢理工大學材料學院復(fù)試試題的詳細答案

1、武漢理工大學材料學院復(fù)試英語口語考察就是問你英語問題，一般只問一個，今年問了許多例如Talk about you hometowm? Talk about Olympic Games? Which sport is you favorite?之類的，大多都是跟生活相關(guān)的問題。我的問題是Do you like research? What kind of job do you want to do after you graduate? 在這個方面平時口語不錯的同學也不會感到很困難。老師面試的時候可能提的問題為：（中文回答）1. 就你的英語自我介紹中提到一個問題。如你的愛好為計算機，老師會問計算

2、機在材料中的運用有哪些？2. 你的畢業(yè)論文的題目是什么，主要的內(nèi)容是什么，有什么新穎的地方等等，用幾句話概括一下？3. 你報考的方向是什么，為什么報這個方向，你對這個方向有什么建議等4. 你是外校的話，為什么你要報武漢理工5. 你想在研究生這個時段做什么方面的研究、現(xiàn)在有什么打算不，等6. 你最擅長哪種材料（4大材料之1）,你對這種材料的生產(chǎn)、制備過程、功能，運用有哪些了解？如果你了玻璃的話，他一般會問你，它的生產(chǎn)過程是什么？7. 談你的研究課題,你有什么研究方案,還會問你一些關(guān)于這個課題的基礎(chǔ)知識。8. 其它問題面試不要緊張，要平靜，回答問題要注意簡潔性，不要長篇大論，要言簡意賅武漢理工大學

3、材料學院復(fù)試試題的詳細答案1.目前用于材料合成與制備的新的方法有許多，請舉例其中的1種并加以說明？ 答：（1）等離子體化學氣相沉積法(PCVD) PVCD是借助等離子體內(nèi)的高能電子與反映氣體原子,分子發(fā)生非彈性碰撞使之離解或電離,從而產(chǎn)生大量的沉積組元,如原子,離子或活性基團并輸送到基體表面上沉積成膜的. 非平衡等離子體激活代替?zhèn)鹘y(tǒng)的加熱激活是PCVD的主要優(yōu)點,可使基體的沉積溫度變較低. 由于其沉積溫度低,沉積速率快,繞鍍性好,設(shè)備操作維護簡單而廣泛用于沉積各種薄膜和超硬膜. 此法得到的膜純度高,致密,形成的結(jié)晶定向好,電子工業(yè)中廣泛用于高純材料和晶體材料的制備. 所涉及的化學反應(yīng)有:熱解反

4、應(yīng),氧化還原反應(yīng),復(fù)合還原反應(yīng)等. （2）溶膠-凝膠法(sol-gel) 溶膠-凝膠法是指有機或無機化合物經(jīng)過溶液-溶膠-凝膠而固化. 經(jīng)過熱處理而制得氧化物或其它化合物固體的方法. 由于溶膠凝膠過程中有著純度高,均勻性強,處理溫度低,反應(yīng)條件易控制等優(yōu)點而廣泛應(yīng)用于特殊光學玻璃,特殊薄膜,超細粉,復(fù)合材料,光學纖維,生物材料等領(lǐng)域. 其主要特點有: 1.可低溫合成氧化物,使得制造無法高溫加熱的制品成為可能; 2.提高材料的均勻性,多成分系溶液是分子級,原子級的混合; 3.可提高生產(chǎn)效率. 其可制得的材料主要有: 塊狀材料,纖維材料,涂層和薄膜材料,超細粉末材料及復(fù)合材料. 所涉及的反應(yīng)有:

5、1.溶劑化; 2.水解反應(yīng); 3.縮聚反應(yīng). 2.選擇兩種測試方法，并簡述其內(nèi)容？ 答：（1）XPS（X射線光電子能譜分析） 電子能譜是近幾十年發(fā)展起來的一種研究物質(zhì)表面性質(zhì)和狀態(tài)的新興物理方法，這里的表面指固體最外層的1-10個原子的表面層，一般為1到幾個nm。 光電子能譜是用X射線作激發(fā)源，轟出樣品中元素的內(nèi)層電子，并直接測量二次電子的能量，這能量表現(xiàn)為元素內(nèi)層電子的結(jié)合能Eb，Eb隨元素而不同，且有較高的分辨力，可以得到從價電子到K殼層的各級電子電離能，有助于了解離子的幾何構(gòu)型和軌道成鍵特性。 其測量原理公式由光電效應(yīng)得來：hv=Eb+Ek+。 應(yīng)用XPS可進行：1 化學分析：包括元素的

6、成分分析和定量分析2 固體表面相研究 3 化合物結(jié)構(gòu)的測定 可用來進行水泥熟料中硅酸鈣的水化表面分析分析能譜中O1s峰的寬窄變化和峰移動的方向可以判斷水化反應(yīng)的進行與否對其表面ESCA測定的Ca/Si比值可以分析水化過程及其產(chǎn)物 （2）透射電子顯微分析 透射電鏡是用聚焦電子束作為照明源，均勻照射到試樣的某一待觀察微小區(qū)域上，由于使用對電子束透明的薄膜試樣，故絕大部分電子穿透試樣，其強度分布與所觀察試樣區(qū)的形貌，組織，結(jié)構(gòu)一一對應(yīng)。經(jīng)過轉(zhuǎn)換可以在熒光屏上顯示出與試樣形貌，組織，結(jié)構(gòu)相應(yīng)的圖象。 其電子圖象的襯度來源于質(zhì)量襯度，衍射襯度和相位襯度。 透射電子顯微鏡是一種高分辨率（分辨率可達0。1n

7、m），高放大倍數(shù)（80萬倍）的顯微鏡。很適合觀察和分析材料的形貌，結(jié)構(gòu)，晶體中的位錯，層錯，空位團等晶體缺陷。 透射電鏡法要求試樣厚度僅為100-200nm，甚至幾十nm的，對電子束“透明”的試樣。試樣大致有三種：超細粉末顆粒，用一定方法減薄的材料薄膜，用復(fù)型方法將材料表面形貌復(fù)制下來的復(fù)型膜。 3.材料科學與工程的概念是什么？其四大要素是什么？其3大特點是什么？ 答：材料科學與工程就是研究有關(guān)材料組成, 結(jié)構(gòu), 制備工藝流程與材料性能用途關(guān)系的知識及應(yīng)用。 其四個要素為: 組成與結(jié)構(gòu),合成與生產(chǎn)過程, 性能, 使用效能。 材料科學與工程的特點： 1多學科交叉材料科學與工程與物理學,化學,冶金

8、學,金屬學,陶瓷學,計算數(shù)學等多學科交叉和結(jié)合的特點. 2具有鮮明的工程性材料科學是面向?qū)嶋H,為經(jīng)濟建設(shè)服務(wù)的,是一門應(yīng)用科學. 實驗室里的研究成果必須通過工程研究開發(fā)以確定合理的工藝流程,最后批量生產(chǎn)出符合要求的工程材料. 3處于發(fā)展中的學科材料科學沒有象力學,電學那樣完整的學科體系,是一門處于不斷發(fā)展之中的學科. 4.結(jié)合自己所學的專業(yè)，敘述本專業(yè)的2個熱點問題？ 答：（1）燃料電池 近二,三十年來,由于一次能源的匱乏和環(huán)境保護的突出,要求開發(fā)利用新的清潔再生能源. (燃料電池由于具有能量轉(zhuǎn)化率高,對環(huán)境污染小等優(yōu)點受到世界各國的普遍重視) 燃料電池是一種將所提供燃料的化學能直接變換為電能

9、的高效能量轉(zhuǎn)換裝置; 是既水力,火力,核力后的第四類發(fā)電技術(shù). 其特點有: 1.由于化學能直接轉(zhuǎn)化為電能,與普通發(fā)電方式相比,避免了能量形式的變化不受卡諾循環(huán)限制, 能量轉(zhuǎn)化效率高. 2.環(huán)保. 廢氣如SOx,NOx,CO2等的排放量極低. 此外,由于電池中無運動部件,工作時非常安靜. 3.電池的本題的負荷反應(yīng)性能好,可靠性高。 （2）碳納米管 是一種具有特殊結(jié)構(gòu)的一維量子材料(徑向尺寸為納米級,軸向尺寸為微米級). 它主要由六邊形排列的碳原子構(gòu)成數(shù)層到數(shù)十層的同軸圓管,層與層之間保持固定的距離. 作為一維納米材料,重量輕,六邊形結(jié)構(gòu)連接完美,具有許多異常的力學,電學性能: 1力學性能 其密度

10、只有鋼的1/6,結(jié)構(gòu)與高分子材料相似,但抗拉強度極大,彈性模量達1TPa,用其增強的塑料力學性能優(yōu)良且抗疲勞,抗蠕變,形變小,滑動性能好. 2電學性能 利用其結(jié)構(gòu)中空的特點,可作為制造某些納米尺度金屬導(dǎo)線的模具. 有些管徑的碳納米管是性能優(yōu)于石墨材料的良好導(dǎo)體,另一些管徑可能是半導(dǎo)體. 3導(dǎo)熱性能 其擁有非常大的長徑比,因而其沿長度方向的熱交換性能很高,垂直方向熱交換性能較低,故其可制成高各向異性熱傳導(dǎo)材料。 考研英語口語復(fù)試完整版范文1. 自我介紹(self-introduce)   Good morning.
