簡介：1出處MATERIALSSCIENCEANDENGINEERINGA,2005,413545549太陽能級多晶硅的長晶速率和雜質(zhì)分布RKVANDE,?MJ?S,BRYNINGEN摘要在工業(yè)規(guī)模的多晶鑄錠爐中，定向凝固法鑄造多晶硅的長晶速率是由固液界面位置變化情況決定的。兩個實驗讓硅從底部以接近平直的固液界面垂直向上生長，凝固完后以不同的速率冷卻。發(fā)現(xiàn)4106米/秒的平均凝固速率和從坩堝底部溫度的計算值相吻合。檢測多晶硅錠生長方向上的碳氧分布和少子壽命。在兩塊多晶硅錠中，碳的分布是很相似的，它在多晶硅錠中間位置的濃度大約都是4PPMA。緩慢冷卻時發(fā)現(xiàn)多晶硅錠中有更高的氧濃度。這是由于涂層質(zhì)量差增加了坩堝中氧向熔硅中的擴散導(dǎo)致的結(jié)果?？焖倮鋮s的多晶硅錠的少子壽命被發(fā)現(xiàn)是大約10ΜM，然而緩慢冷卻的少子壽命只有2ΜM緩慢冷卻具有較低的少子壽命可能是由鐵從坩堝向熔體中擴散導(dǎo)致的結(jié)果。◎2005年BV出版社版權(quán)所有關(guān)鍵詞定向凝固，多晶硅，凝固速率，雜質(zhì)分，少子壽命1簡介多晶硅是太陽能電池制造中最常用的材料，它占到全球太陽能光伏組件的50以上。定向凝固法是鑄造太陽能級多晶硅的常用方法。它的原理是硅料熔化后把熱量從坩堝底部抽出，進而形成接近平直的固液界面從底部開始凝固。大部分雜質(zhì)被分離到硅錠頂部，并且最后的晶體結(jié)構(gòu)主要是平行于晶體生長方向的大柱狀晶粒。太陽能級多晶硅的光電轉(zhuǎn)換效率一般在1215這個范圍。光電轉(zhuǎn)換效率主要是由位錯間少數(shù)載流子的復(fù)合以及晶粒內(nèi)的缺陷例如雜質(zhì)、小的原子集團或者沉淀限制的。由于單純位錯間的復(fù)合被認為是相對較弱的，這也就暗示了這些區(qū)域的金屬雜質(zhì)和沉淀是增強再結(jié)晶能力的原由。眾所周知，多晶硅凝固過程嚴重影響著電池片的光電轉(zhuǎn)換效率。多晶硅的凝固決定著材料的結(jié)構(gòu)，而且快速冷卻凝固被認為影響著硅錠的位錯密度，固液界面的曲率可能影響著晶體的形態(tài)和雜質(zhì)在硅錠中的位置。碳和氧還有氮是多晶硅3硅錠的性能隨生長方向的變化進行了研究。切割過程中去除樣品底部的部分。傅立葉變換紅外光譜儀用來測量多晶硅錠中的碳氧含量。傅立葉變換紅外光譜儀可測量替代位氧濃度和間隙氧濃度分別從01PPMA和02PPMA到它們在硅中的最大溶解度。這些測量是在個表面拋光的2MM厚的樣品上進行的，并用標(biāo)準的測量在來兩個多晶硅錠的生長方向進行碳氧含量的測量。準穩(wěn)態(tài)光電導(dǎo)衰減儀被用來測量多晶硅錠中的少子壽命，這些測量是在2CM厚的樣品上進行的。圖1從上面觀察用于進一步分析多晶硅錠試樣的位置。表1熱量分別在硅（SI，S），坩堝（CR），石墨（G）中的熱傳導(dǎo)3結(jié)果31凝固假設(shè)熱量是從坩堝底部輻射出去的，則凝固的界面位置可以通過一個樣品的熱傳導(dǎo)模型計算出來。當(dāng)假設(shè)所有的界面具有相同的區(qū)域A（圖2）在固體硅，石英坩堝以及坩堝底部石墨絕緣材料的熱傳導(dǎo)可以用表1來表示。圖2系統(tǒng)的溫度和厚度變化曲線圖3凝固高度的計算值和測量值隨時間的變化曲線聯(lián)立公式（1）（3）并且假設(shè)QSI,SQCRQGQ,可以得出下面的公式在凝固過程中假定熱傳導(dǎo)系數(shù)是不同的，冷卻溫度TP是用熱電偶測量的。經(jīng)過結(jié)晶的固態(tài)硅的熱傳導(dǎo)可以表達為△H是硅的熱焓，ΡSI是硅的密度，MSI是硅的摩爾質(zhì)量,V是硅的長晶速率，

簡介：畢業(yè)設(shè)計（論文）外文翻譯題目基于OD矩陣神經(jīng)網(wǎng)絡(luò)與主成分分析法的路段流量估算專業(yè)矩陣。為了克服這個局限性，CASCETTA（1989）提出了一種像隨機變量的闡明來解釋鏈接和路徑流動，因此，就獲得了這些變量平均值的價值。在這一研究方向也有其他人的論文，比如YANG等人（1992），而且在不斷的改善（YANG等人，2001）；這些人在1996年提出了一種使OD矩陣估算使用的同時鏈接流量數(shù)據(jù)和信息的鏈接選擇比例的統(tǒng)計方法。GONG在1998年使用一個神經(jīng)網(wǎng)絡(luò)當(dāng)作一個工具，用以求解最優(yōu)化的問題，但是在同一類引用之前，由一個平均信息量最大化的問題。本論文為了解決共享計算機技術(shù)的OD矩陣估算，特別是從道路網(wǎng)絡(luò)流量鏈接的神經(jīng)網(wǎng)絡(luò)知識。它工作的一個應(yīng)用多層前饋神經(jīng)網(wǎng)絡(luò)OD矩陣利用接近的典型的特征來估算；沒有松動的共性，它們被假定鏈接一個測量和OD矩陣的連續(xù)關(guān)系上。由于前饋神經(jīng)網(wǎng)絡(luò)的學(xué)習(xí)機制，無論如何，同時期的相關(guān)鏈接流OD矩陣的知識使極其必要的。這個要求多虧了那不勒斯大學(xué)的運輸實驗（BIFULCO,2004）,他們匯總了所有必要的和那些通常不容易實地收集到的信息，并且具有必要的完整性。2數(shù)據(jù)預(yù)處理信號的清理和標(biāo)準化對于接下來得到一個更簡單神經(jīng)網(wǎng)絡(luò)使很有必要的。其基本思想是可以把這個問題歸結(jié)為固定條件下減少問題,如果不能,則穩(wěn)定之間的關(guān)系及其方差信號。在本文，我們主要集中在信號方差穩(wěn)定階段，我們沒有缺失數(shù)據(jù)或有錯誤的測量結(jié)果。在文學(xué)的定義，有幾個穩(wěn)定形成了強大的意義上，我們可以完成完整的陳述過程，但這是這不實際，因為需要指定無限對分配的約束矩（BITTANTI,1986）。一個簡單的方法來降低問題的穩(wěn)定性二階統(tǒng)計量即信號分布可被完全描述使用前兩階矩施加恒定的期望值和一種基于協(xié)方差函數(shù)獨立于具體??,EVTMT??的時間,但是基于指標(biāo)只能依賴于它們的區(qū)別??VREVTMVTM??????。接下來時間的不變轉(zhuǎn)移讓我們使用這個較弱的假定期望值和發(fā)差的21TT???穩(wěn)定性。弱的平穩(wěn)過程所涉及的是經(jīng)典最小二乘法最小化的方法。自從反向誤差函數(shù)最小化，通過訓(xùn)練程序?qū)W習(xí)神經(jīng)網(wǎng)絡(luò)的權(quán)值也屬于這個框架,能夠成為一個經(jīng)典的梯度下降或另一種訓(xùn)練算法的總和,是平方誤差之間（KDIMENSIONAL）目標(biāo)價值和網(wǎng)絡(luò)的輸出。NT?NY?
