內容簡介

　　 高壓電力電纜載流量是電纜運行中受到環境條件、敷設方式等多種因素影響的重要動態運行參數，是保證電力電纜在壽命周期內安全、可靠、穩定運行的重要保障。《高壓電力電纜載流量數值計算》分兩部分介紹有關電纜載流量的計算方法。
　　 第一部分簡單介紹目前常用的IEC一60287計算標準，給齣載流量的解析計算公式，損耗因數的計算方法，熱阻的計算方法。
　　 第二部分詳細介紹瞭利用有限無法計算電力電纜焦耳損耗、溫度場分布的過程，利用迭代法實現電磁場和溫度場的耦閤計算過程，利用迭代法實現載流量的計算過程，以及基於環境因素監測和有限元溫度場計算的實時載流量預測方法。
　　 在穩態溫度場和載流量計算的基礎上，《高壓電力電纜載流量數值計算》介紹瞭利用有限差分和有限元相結閤的方法，計算暫態溫度場和載流量的計算過程。

作者簡介

　　西奧多·德萊塞（1871－1945），美國現代小說的先驅和代錶作傢，被認為是同海明威、福剋納並列的美國現代小說的三巨頭之一。他齣生於印第安納州特雷霍特鎮。父親是貧苦的德國移民。德萊塞在公立學校接受瞭早期教育，之後進入印第安納大學學習，一生的大部分時間從事新聞工作。他走遍瞭芝加哥、匹茲堡、紐約等大城市，廣泛深入地觀察瞭解社會，為日後的文學創作積纍瞭豐富的素材。德萊塞一生著作頗豐，第一部小說為《嘉莉妹妹》（1900），通過農村姑娘嘉莉到芝加哥謀生而成為知名舞颱演員的故事，揭露瞭資本主義社會繁榮外衣掩蓋下的生存鬥爭，對美國貧富對立的社會作瞭深刻的描寫。1911年，《珍妮姑娘》問世，接著又發錶瞭《欲望三部麯》的前兩部《金融傢》（1912）和《巨人》（1914），奠定瞭德菜塞在美國文學界的地位。《天纔》（1915）是德萊塞自己滿意的一部長篇小說，通過一位青年畫傢的墮落控訴瞭資本主義社會對藝術的摧殘。以真實的犯罪案件為題材的《美國的悲劇》（1925）是德萊塞的代錶作。他的藝術特色--廣闊的社會畫麵，豐富麯摺的情節，深入細緻的心理描述，不同情景的對比手法及獨具個性的語言，統統體現在這部傑作中。可以說，《美國的悲劇》達到瞭德萊塞藝術創作的高峰。

　　misgivings-and they were as plentiful as the moments of the day-she was still happy.She could not repress her delight in doing this little thing which，to an ordinary observer，had no importance at all.　　Hurstwood was charmed by the development of the fact that the girl had capabilities There is nothing so inspiring in life as the sight of a legitimate ambition， no matter how incipient.It gives color，force，and beauty to the possessor.　　Carrie was now lightened by a touch of this divine afflatus.She drew to herself commendationca from her two admirers which she had not earned.Their affection for her naturally heightened their perception of what she was trying to do and their approval of what she did.Her inexperience conserved her own exuberant fancy，which ran riot with every straw of opportunity，making of it a golden divining rod whereby the treasure of life was to be discovered.　　"Let's see，" said Hurstwood，"I ought to know some of the boys in the lodge.I'm an Elk myself."　　"Oh，you mustn't let him know I told you."　　"That's so，"said the manager.　　"I'd like for you to be there，if you want to come，but I don't see how you can unless he asks you."　　"I'll be there，"said Hurstwood affectionately."I can fix it so he won't know you told me.You leave it to me."　　This interest of the manager was a large thing in itself for the performance，for his standing among the Elks was something worth talking about.Already he was thinking of a box with some friends，and flowers for Came.He would make it a dress-suit affair and give the little girl a chance.　　Within a day or two，Drouet dropped into the Adams Street resort，and he was at once spied by Hurstwood.It was at five in the afternoon and the place was crowded with merchants， actors，managers，politicians，a goodly company of rotund，rosy figures，silk-hatted，starchy-bosomed，beringed and bescarfpinned to the queen's taste.John L.Sullivan，the pugilist，was at one end of the glittering bar， surrounded by a company of loudly dressed sports， who were　　holding a most animated conversation.Drouet came across the floor with a festive stride，a new pair of tan shoes squeaking audibly at his progress.　　"Well，sir，" said Hurstwood， " I was wondering what had become of you.I thought you had gone out of town again."　　Drouet laughed.　　"If you don't report more regularly we'll have to cut you off the list."　　" Couldn't help it，"said the drummer，"I've been busy."　　They strolled over toward the bar amid the noisy， shifting company of notables.The dressy manager was shaken by the hand three times in as many minutes.　　"I hear your lodge is going to give a performance，" observed Hurstwood，in the most of ihand manner.　　"Yes，who told you?"　　"No one，" said Hurstwood."They just sent me a couple of tickets，which I can have for two dollars.Is it going to be any good?"　　"I don't know，" replied the drummer."They've been trying to get me to get some woman to take a part."　　"I wasn't intending to go，" said the manager easily."I'll subscribe，of course.How are things over there?"　　"All right.They're going to fit things up out of the proceeds."　　"Well，"said the manager，"I hope they make a success of it.　　Have another?"　　He did not intend to say any more.Now，if he should appear on the scene with a few friends，he could say that he had been urged to come along.Drouet had a desire to wipe out the possibility of confusion.　　"I think the girl is going to take a part in it，" he said abruptly，after thinking it over.　　"You don't say so! How did that happen?"　　"Well，they were short and wanted me to find them someone.I told Carrie，and she seems to want to try."　　" Good for her，" said the manager."It'll be a real nice affair.Do her good，too.Has she ever had any experience?"　　" Not a bit."　　" Oh，well，it isn't anything very serious."　　" She's clever，though，" said Drouet， casting off any imputation against Carrie's ability."She picks up her part quick enough."　　"You don't say so! " said the manager.　　"Yes，sir; she surprised me the other night.By George，if she didn't."　　" We must give her a nice little send-off，" said the manager."I'll look after the flowers."　　Drouet smiled at his good nature.　　"After the show you must come with me and we'll have a little supper."　　"I think she'll do all right，"said Drouet.　　"I want to see her.She's got to do all right.We'll make her，" and the manager gave one of his quick， steely half-smlles， which was a compound of good nature and shrewdness.　　Carrie， meanwhile， attended the first rehearsal.At this performance Mr.Quincel presided，aided by Mr.Millice，a young man who had some qualifications of past experience，which were not exactly understood by any one.He was so experienced and so businesslike，how ever，that he came very near being rude-failing to rememberias resort，and he was at once spied by Hurstwood.It was at five in the　　afternoon and the place was crowded with merchants， actors，managers，politiaans，a goodly company of rotund，rosy figures，silk-hatted，starchy-bosomed，beringed and bescarfpinned to the queen's taste.John L.Sullivan，the pugilist，was at one end of the glittering bar， surrounded by a corupany of loudly dressed sports， who were holding a most animated conversation.Drouet came across the floor　　with a festive stride，a new pair of tan shoes squeaking audibly at his progress.　　" Well，sir， " said Hurstwood， "I was wondering what had become of you.I thought you had gone out of town again."　　Drouet laughed.　　"If you don't report more regularly we'll have to cut you off the list."　　" Couldn't help it，" said the drummer，"I've been busy."　　They strolled over toward the bar amid the noisy， shifting company of notables.The dressy manager was shaken by the hand three times in as many minutes.　　"I hear your lodge is going to give a performance，" observed Hurstwood，in the most offthand manner.　　"Yes，who told you?"　　"No one，" said Hurstwood."They just sent me a couple of tickets，which I can have for two dollars.Is it going to be any good?"　　"I don't know，" replied the drummer."They've been trying to get me to get some woman to take a part."　　"I wasn't intending to go，" said the manager easily."I'll subscribe，of course.How are things over there?"　　"All right.They're going to fit things up out of the proceeds."　　"Well，"said the manager，"I hope they make a success of it.　　Have another?"　　……
