【正文】 s head while he died. So it goes. Derby was forty four years o。d been in Roland Weary39。t been in Billy39。s upper right arm with his thumb and forefinger, asked a panion what sort of an army would send a weakling like that to the front. They looked at the other American bodies now, pointed out a lot more that were nearly as bad as Billy39。t anything warm or lively to attract them merely long, low, narrow sheds by the thousands, with no lights inside. Somewhere a dog barked. With the help of fear and echoes and winter silences, that dog had a voice like a big bronze gong. Billy and the rest were wooed through gate after gate, and Billy saw his first Russian. The man was all alone in the nighta ragbag with a round, flat face that glowed like a radium dial. Billy passed w ithin a yard of him. There was barbed wire between them. The Russian did not wave or speak, but he looked directly into Billy39。s fur collar. Billy glanced dully at the coats of his neighbors. T heir coats all had brass buttons or tinsel or piping or numbers or stripes or eagles or moons or stars dangling from them. They were soldiers39。t hay after all. They were overcoats taken from prisoners who were dead. So it goes. It was the guards39。t. want to drop from the car to the ground. He sincerely believed that he would shatter like glass. So the guards helped him down, cooing still. T hey set him down facing the train. I t was such a dinky train now. There was a lootive, a tender, and three little boxcars. The last boxcar was the railroad guards39。s car owlishly, cooed calmingly. They had never dealt w ith Americans before, but they surely understood this general sort of freight. They knew that it was essentially a liquid which could be induced to flow slowly toward cooing and light. It was nighttime. The only light outside came from a single bulb which hung from a polehigh and far away. All was quiet outside, except for the guards, who cooed like doves. And the liquid began to flow. Gobs of it built up in the doorway, plopped to the ground. Billy was the nexttolast human being to reach the door. The hobo was the last. The hobo could not flow, could not plop. He wasn39。 Listen on the tenth night the peg was pulled out of the hasp on Billy39。s room. Her drawers were dumped. her closet was empty. Heaped in the middle of the room were all the possessions she could not take on a honeymoon. She had a Princess telephone extension all her ownon her windowsill Its tiny night light stared at Billy. And then it rang. Billy answered. There was a drunk on the other end. Bi 39。s partners in the New Holiday Inn. There was a full moon. Billy got out of bed in the moonlight. He felt spooky and luminous felt as though he were wrapped in cool fur that was full of static electricity. He looked down at his bare feet. They were ivory and blue. Billy now shuffled down his upstairs hallway, knowing he was about to be kidnapped by a flying saucer. The hallway was zebra striped with darkness and moonlight. The moonlight came into the hallway through doorways of the empty rooms of Billy39。t need to be jiggled to sleep. Valencia was snoring like a bandsaw. T he poor woman didn39。 系統(tǒng)退出 This boothwn outside, each car became a single anism which ate and drank and excreted through its ventilators. It talked or sometimes yelled through its ventilators, too. In went water and loaves of blackbread and sausage and cheese, and out came shit and piss and language. Human beings in there were excreting into steel helmets, which were passe d to the people at the ventilators, who dumped them. Billy was a dumper. The human beings also passed canteens, which guards would fill with water. When food came in, the human beings were quiet and trusting and beautiful. They shared. Human beings in there took turns standing or lying down. The legs of those who stood were like fence posts driven into a warm., squirming, fa tting, sighing earth. The queer earth was a mosaic of sleepers who nestled like spoons. Now the train began to creep eastward. Somewhere in there was Christmas. Billy Pilgrim nestled like a spoon with the hobo on Christmas night, and he fell asleep, and he traveled in time to 1967 againto the night he was kidnapped by a flying saucer from Tralfamadore. Four Billy Pilgrim could not sleep on his daughters wedding night. He was forty four. The wedding had taken place that afternoon in a gaily striped tent in Billy39。 [圖 8] (7)管理員設(shè)置界面 可以對(duì)登陸的用戶進(jìn)行添加，修改，查詢的設(shè)置。 [圖 6] (5)會(huì)員查詢界面 可以對(duì)會(huì)員進(jìn)行編號(hào)，姓名，班級(jí)的查詢。 [圖 4] 在本窗體中需要用戶填寫用戶登錄名、用戶口令 在這個(gè)窗體中登錄的用戶會(huì)進(jìn)入整個(gè)系統(tǒng)中，添加、修改、刪除的功能，當(dāng)用戶 3次登錄都失敗時(shí)系統(tǒng)會(huì)自動(dòng)關(guān)閉。當(dāng)管理員 點(diǎn)擊“進(jìn)入”按鈕時(shí)，就會(huì)出現(xiàn)“登錄”窗體。該系統(tǒng)執(zhí)行時(shí)，先錄入數(shù)據(jù)，然后根據(jù)會(huì)員的個(gè)人信息可以進(jìn)行查詢以及按照相同的屬于進(jìn)行排序，并可將結(jié)果進(jìn)行預(yù)覽。 軟件模塊結(jié)構(gòu)設(shè)計(jì) 1系統(tǒng)方案確定 通過(guò)對(duì)系統(tǒng)調(diào)研與分析，系統(tǒng)主要應(yīng)完成的功能如下：會(huì)員信息錄入、會(huì)員信息查詢、系統(tǒng)維護(hù)等三 大模塊。 (3) 超級(jí)用戶表： ID，超級(jí)用戶名，密碼。我創(chuàng)立以下幾個(gè)數(shù)據(jù)表： (1) 會(huì)員表：編號(hào)，姓名，性別，專業(yè)，班級(jí)，宿舍，電話，社團(tuán)部，職位，會(huì)費(fèi)，年，月，日。 只 顯 示 會(huì) 員 相 關(guān) 信 息 。目前在我國(guó)市場(chǎng)上最為流行、使用最多、最為先進(jìn)的可用作企業(yè)級(jí)開發(fā)工具的產(chǎn)品有： Microsoft 公司的 Visual 公司的 Visual 公司的 Delphi.
