Billy39。 The dog, who had sounded so ferocious in the winter distances, was a female German shepherd. She was shivering. Her tail was between her legs. She had been borrowed that morning from a farmer. She had never been to war before. She had no idea what game was being played. Her mine was Princess. Two of the Germans were boys in their early teens. Two were ramshackle old me droolers as toothless as carp. They were irregulars, armed and clothed fragmentarily with junk taken from real soldiers who were newly dead. So it goes. They were farmers from just across the German border, not far away. Their manander was a middleaged corporalredeyed., scrawny, tough as dried beef, sic k of war. He had been wounded four timesand patched up, and sent back to war. He was a very good soldierabout to quit, about to find somebody to surrender to. His bandy legs were thrust into golden cavalry boots which he had take n from a dead Hungarian colonel on the Russian front. So it goes. Those boots were almost all he owned in this world. They were his home. An anecdote: One time a recruit was watching him bone and wax those golden boots, and he held one up to the recruit and said, 39。Nice playthings you have, the corporal told Weary, and he handed the knife to an old man. 39。What a lucky pony, eh?39。 and they had to walk for miles and miles, with Weary39。s optometer in his office in Ilium. An optometer is an instrument for measuring refractive errors in eyesin order that corrective lenses may be prescribed. Billy had fallen asleep w hile examining a female patient who was m a chair on the other side of the owl. He had fallen asleep at wor k before. It had been funny at first. Now Billy was starting to get worried about it, about his mind in general. He tried to remember how old he was, couldn39。re so quiet.39。You see something terrible?39。s why they lose their names when they bee dogpillars. He nodded while scratching the dogpillar39。m not criticizing you. I39。s not talk about it. You never know where someone might be listening. You39。d better go, I said. He turned a sadly smiling face toward me and bowed slightly. After stroking the dogpillar39。s time for the mail truck to e. Talking pains to look at my watch, I stood up. I39。d gone on boldly writing social criticism and had been arrested. There are even times when I think that. But I was just a dilettante, never knowing poverty, craving peaceful dreams. I wanted to live a fortable life. As a person strong in self respect, I couldn39。s profile. Now that he said so, it was a face I seemed to have seen somewhere before. I started to ask his name, hesitated, and fell silent. The elderly man said abruptly, It39。t that a strange law? The man gave me a quick glance, then replied casually. Didn39。Um.39。 he said. 39。 30 Then he made Weary sit down in the snow and take off his bat boots, which he gave to the beautiful boy. He gave Weary, the boy39。s breast pocket, over his heart. It is sheathed in steel. The corporal found the dirty picture of the woman and the pony in Weary39。s pistol to the pretty boy. He marveled at Weary39。s fans, the divinely listless loveplay that follows the asm of victory. It is called 39。s funny, huh?39。 感謝許學(xué)敏同學(xué)和李維綱同學(xué)，他們一直在鼓勵(lì)我克服學(xué)習(xí)和生活中的困難，使我順利完成論文。 The Design and Realization of Imitating System of Aviation in Selling Tickets Abstract: Either setting or booking tickets is one of the most basis businesses in civil avitation. On the surface, if is a simple business part of civil avitation, but it refers to many aspects,such as caption management and customers , the old traditional selling cannot be content to the object equirement of the increasing diacharge in modern civil avitation, This thesis design is to use developing implement Visual ,which developing selling management system of civil avitation.

In a word ,it can be used in the management of civil avitation easily and quickly. Keywords: booking tickets 。 6 結(jié)束語(yǔ) 實(shí)驗(yàn)結(jié)果表明： 該模擬系統(tǒng)具有現(xiàn)實(shí)中訂票、退票以及一些基本的查詢(xún)功能，開(kāi)發(fā)一個(gè)具有開(kāi)放體系結(jié)構(gòu)的、易擴(kuò)充的、易維護(hù)的、具有良好人機(jī)交互界面的航班售票系統(tǒng)，實(shí)現(xiàn)航空公司的機(jī)票銷(xiāo)售的自動(dòng)化的計(jì)算機(jī)系統(tǒng)，為企業(yè)的決策層提供準(zhǔn)確、精細(xì)、迅速的機(jī)票銷(xiāo)售信息。關(guān)閉命令顯示 SET SAFETY OFF amp。顯示 4位年代 SET DATE YMD amp。 23 系統(tǒng)維護(hù)選擇是通過(guò)三個(gè)選項(xiàng)按鈕來(lái)執(zhí)行的 ,整體布局如圖 所示 : 圖 系統(tǒng)維護(hù)選擇表單圖 在用戶(hù)權(quán)限維護(hù)的操作中，首先需要用戶(hù)選擇操作，如添加新用戶(hù)、刪除舊用戶(hù)或修改原用戶(hù)的密碼等 ,無(wú)論哪一種操作 ,均需要輸入操作者的密碼 ,在操 作者的密碼通過(guò)后才能進(jìn)行相關(guān)的操作。整體布局如圖 所示 : 圖 乘客查詢(xún)和退票表單圖 “ 查詢(xún)乘客 ” 命令按鈕的過(guò)程代碼如下 : .setfocus locate all for alltrim( 乘 客 信 息 數(shù) 據(jù) 表 . 身份證號(hào) )==alltrim() if found() y=reo() go y messagebox(乘客已經(jīng)找到 ,提示乘客先辦理完相關(guān)手續(xù) ,否則不能退票 !) else messagebox(未能找到該乘客 ,請(qǐng)確認(rèn) !) endif “ 確認(rèn)退票 ” 命令按鈕的過(guò)程代碼 : locate all for alltrim ( 乘 客 信 息 數(shù) 據(jù) 表 . 身 份 證號(hào) )==alltrim() if found() if messagebox(當(dāng)前乘客確實(shí)要退票嗎 ?!,32+4+256,開(kāi)戶(hù)確認(rèn) )=6 y=reo() go y 本科畢業(yè)設(shè)計(jì)（論文） 如圖 所示 : 圖 數(shù)據(jù)關(guān)聯(lián)圖 將數(shù)據(jù)環(huán)境中的 “ 乘客信息數(shù)據(jù)表 ” 中的全部字段選中，并一次性地全部拖到表單中，形成一個(gè)表格控件“ grd 乘客信息數(shù)據(jù)表 ” 。 16 本科畢業(yè)設(shè)計(jì)（論文） 5 系統(tǒng)實(shí)現(xiàn) 實(shí)現(xiàn)數(shù)據(jù)庫(kù)的邏輯結(jié)構(gòu)的方式是直接使用 Visual FoxPro 的項(xiàng)目管理器來(lái)實(shí)現(xiàn)的。這樣一個(gè)系統(tǒng)給操作員帶來(lái)很大的方便，減少了手工操作帶來(lái)的麻煩。如果有不滿(mǎn)足訂票信息的或有輸入錯(cuò)誤還可以修改訂票。 “占用標(biāo)記”的字段允許為空，因?yàn)樵谠撟皇鄢鲋埃鼰o(wú)占用標(biāo)記。 “航班座位等級(jí)分配與座位占用表 ” 的邏輯結(jié)構(gòu)定義 在訂票、售票時(shí)，乘客需要指定相關(guān)的座位等級(jí)，系統(tǒng)為它分配一個(gè)座位，在該座位售出之后，需要為該座位作上已經(jīng)“占用”的標(biāo)記。 “航班信息數(shù)據(jù)表 ” 的邏輯結(jié)構(gòu)定義 在“航班信息數(shù)據(jù)表”的邏輯結(jié)構(gòu)定義中，把“航班號(hào)”字段定為主索引字段，因?yàn)橐粋€(gè)航班公司的每一個(gè)航班號(hào)應(yīng)該是唯一的，而 且該字段是用于與“乘客信息數(shù)據(jù)表”建立關(guān)鍵字段。 Visual FoxPro 還提供了一個(gè)集成化的系統(tǒng)開(kāi)發(fā)環(huán)境。本系統(tǒng)的流程 分析如圖 所示： 圖 數(shù)據(jù)流程圖 有了數(shù)據(jù)流圖，我們?cè)谛枨蠓治龅幕A(chǔ)上，設(shè)計(jì)出能夠滿(mǎn)足用戶(hù)需求和各種實(shí)
