【正文】 Amazon dolphins from extermination. We have other tasks too, which I can39。 manatees from being chopped up by speedboat propellers in Florida39。s just one of the reasons why The Eden Mission is a top priority ... Bellingham glanced quickly at his watch. I see time is running out. A few final words. Sea Shepherd39。s face showed her feelings. The naturalist then mentioned another charming practice: eating bear paws. Considered a delicacy in Japan, Taiwan, Hong Kong and Singapore, the paws of hunted bears are imported from China. The wildlife trade is a worldwide business, w orth billions of pounds. There are strict rules to control that trade. However, some countries don39。s voice broke into the boy39。 only the older ones understood that this was no celebration. For several nights to e there would be plenty of bodies to feed the flames. Niy miles inland, nothing broke the forest hush. A full moon silvered the treetops and light leaked down to the snowcovered floor beneath. Scraps of mist seemed caught on prickly branches. From the shadows, a ghostly shape glided into a clearing. Tw o amber eyes searched the dappled darkness. Stealthily the wolf a dvanced. Hunger had driven him from his snug den. He knew where to find a good meal. Not the mice and birds he had lived on lately, but a hare he had killed and buried in the frozen ground to keep it fresh and safe from crows and ravens. As the dogwolf wound through the trees at an effortless lope, which could carry him as far as 120 miles in a single day, his thic k browngrey yellow fur gleamed in the moonlight. He was a fine big dog:owdered horn cured colds, measles, nosebleeds, vomiting, heart weakness. The Japanese claimed it fought fever. Certain people even swore by it as a love potion. Most poachers are poor. So the temptation to earn money by any means, however risky, is very strong. They may work as farmer s for ?00 a year less than they39。s mind. He was busy trying to solve a sixty foot, sixty ton problem: a sperm whale that refused to give up. The harpoon had not found the vital spotthe gunner blamed the choppy sea for spoiling his aim and now the whale was towing the 110 ton boat behind it. Even with the engine reversed, the craft kept moving forward. The gunner got ready to fire a second harpoon. In the bloodstained water the mammoth beast continued its agonising struggle. He was a mature male, a bull. His slateblue body bore scars, souvenirs of epic battles with giant squid he had hunted in the dark depths. The biggest of these pink monsters, whose humanlike eyes were more than fifteen inches across, weighed 42 tons and measured 66 feet. But even the ir powerful beaks and ten suc kered tentacles were no match for the whale39。 除非另有科研合同和其他法律文書的制約,本論文的科研成果屬于成都信息工程學(xué)院。 ( 4)學(xué)??稍试S學(xué)位論文被查閱或借閱。 ( 2)學(xué)??梢圆捎糜坝?、縮印或其他復(fù)制方式保存學(xué)位論文。除非另有說明,本文的工作是原始性工作。 作者簡(jiǎn)介: 姓 名:李 洋 性別:男 出生年月: 1982 年 11 月 民族:漢族 Email: 聲 明 本論文的工作是 2020 年 2 月至 2020 年 6 月在成都信息工程學(xué)院網(wǎng)絡(luò)工程系完成的。同時(shí)也感謝其他老師在此期間的關(guān)懷和幫助,以及學(xué)院為我提供良好的畢業(yè)設(shè)計(jì)環(huán)境。在此期間,我不僅學(xué)到了許多新的知識(shí)和解決問題的方法,而且也開闊了視野,提高了解決問題的能力。 李誼瑞老師淵博的知識(shí)、嚴(yán)謹(jǐn)?shù)闹螌W(xué)態(tài)度深深的影響著我。 在畢業(yè)設(shè)計(jì)的這段日子里,我所獲得的知識(shí)將是大學(xué)期間最珍貴的。 做畢業(yè)設(shè)計(jì)的這段時(shí)間來說,其實(shí)也不是很長(zhǎng),由于時(shí)間倉(cāng)促,以及我掌握知識(shí)的不全面,我的畢業(yè)設(shè)計(jì)中存在這樣或那樣的不足,給我即將 結(jié)束的大學(xué)生活留下了小小的一點(diǎn)遺憾。開發(fā)過程中,充分考慮 用戶的需求,使得本系統(tǒng)操作起來簡(jiǎn)單方便,具有高效的查詢功能,同時(shí)安全、靈活的權(quán)限管理機(jī)制可以方便地對(duì)每個(gè)用戶分配系統(tǒng)各個(gè)功能的使用權(quán)限,最終本系統(tǒng)完成了需求分析所要求的學(xué)生對(duì)教師評(píng)教,教師對(duì)教師評(píng)教以及管理員對(duì)結(jié)果進(jìn)行統(tǒng)計(jì)等功能。實(shí)現(xiàn)功能如圖: 圖 11教師所授課程測(cè)試功能圖 圖 12教師分?jǐn)?shù)測(cè)試功能圖 圖 13查看留言信息圖 管理員統(tǒng)計(jì)功能測(cè)試 管理員可以根據(jù)輸入查詢的條件對(duì)學(xué)生,教師的評(píng)論結(jié)果進(jìn)行查看,同時(shí)還可以查看教師在院系的排行。 首先,學(xué)生通過用戶名和帳號(hào)進(jìn)入到學(xué)生界面,點(diǎn)擊網(wǎng)上評(píng)教,進(jìn)入評(píng)教頁面,開始打分,如果學(xué)生對(duì)此教師有好的建議可以通過點(diǎn)擊留言鏈接進(jìn)行留言。軟件完成后,進(jìn)行系統(tǒng)測(cè)試。 } 6 系統(tǒng)測(cè)試 系統(tǒng)的功能測(cè)試是在編碼的過程中完成的。 } } (C:\)。jcolumn。irow。 var objSheet=。 =true。 column=(1).。 script language=javascript function outExcel(){ var table=。設(shè)計(jì)過程中,主要是應(yīng)用 JAVASCRIPT 的構(gòu)造函數(shù)創(chuàng)建了一個(gè) EXCEL。 ()。 ()。 group by ID, , , ,teacher.所授課程 , , order by 8 desc。 String sql=select ID,名 , , , , ,級(jí) ,avg( )as 分?jǐn)?shù) from teacher,score where = 姓名 and = and =39。 % if((name0)!=null){ String colloe=(name0)。 ()。+(name1)+39。+(name0)+39。并能打印排行榜表。 在統(tǒng)計(jì)功能中,管理員可以通過表單對(duì)教師及其所授課程的輸入,查看學(xué)生對(duì)此教師的評(píng)分,同時(shí)計(jì)算出總分和平均分,管理員還可以根據(jù)具體情況對(duì)評(píng)分結(jié)果進(jìn)行刪除。 管理員頁面及其基本功能的實(shí)現(xiàn) 此頁面管理員主要對(duì)學(xué)生,教師,課程信息進(jìn)行查詢,更改,錄入等操作以及對(duì)統(tǒng)計(jì)結(jié)果的操作,對(duì)信息處理就不重點(diǎn)介紹了。+lid+39。+biaoshi+39。 //實(shí)現(xiàn)次留言為已查看留言 if((留言 )!=null){ String biaoshi=no。+lid+39。 int lid=(id)。 (2) 留言信息 //留言信息的顯示 String id=(id)。 int i=()。 ResultSet rs=(sql)。) and 標(biāo)識(shí) =39。 String sql=select * from liuyan where 教師姓名 in(select 教師姓名 from teacher where 教師 ID=39。在此部分的實(shí)現(xiàn)過程中,判斷是否有新留言,我在留言表中設(shè)置了個(gè)標(biāo)識(shí)字段,當(dāng)為 yes 的時(shí)候,此條留言為新留言,當(dāng)教師查看后,標(biāo)識(shí)變?yōu)?no,表示已經(jīng)查看的留言。} //平均分 % avg=(double)(sum/count)。icount。 ()。 ()。+course+39。+cla+39。 int i。 int sum=0。 course=new String((ISO88591),gbk)。 cla=new String((ISO88591),gbk)。在此部分的實(shí)現(xiàn)過程中,利用了超鏈接傳遞班級(jí)和課程信息。 } } catch(SQLException e) 教師頁面及基本功能的實(shí)現(xiàn) 在上面的學(xué)生頁面中具體介紹了學(xué)生模塊的各個(gè)功能,教師模塊部分功能與其大同小異,這里就不一一介紹了,重點(diǎn)介紹下幾個(gè)關(guān)鍵的功能實(shí)現(xiàn)。 (sql)。 where 密碼=39。 else { sql=Update student Set 密碼 =39。 try { ()。+opassword+39。 else if (!(renpassword)) (確認(rèn)新密碼不正確! )。 String renpassword=(trenpassword)。 (2) 更改密碼 String opassword=(topassword)。關(guān)鍵代碼如下: (1) 退出 %()。同時(shí)也建議用戶經(jīng)常更改個(gè)人密碼。+biaoshi+39。+(name)+39。+bname+39。 if((board)!=null){ String bname=(board)。 ()。,+score+)。,39。,39。 String sql=insert score( 學(xué)號(hào) , 教 師 姓 名 , 課 程 名 稱 , 分?jǐn)?shù) ) values(39。 ……… // 代碼的剩略 s20=(t20)。 int sun=0。 int score=0。 (4) 評(píng)分錄入數(shù)據(jù)庫(kù) String t1=(t1)。 (name,name)。 name=new String((ISO88591),gbk)。name=%=name% target=_top (3) request 對(duì)象和 session 對(duì)象傳遞值的應(yīng)用 String name=(name)。 ()。+course+39。+name+39。+(username)+39。代碼方面將會(huì)多次運(yùn)用到 JSP 中的 request 對(duì)象和 session 對(duì)象,同時(shí)也會(huì)運(yùn)用到超鏈接來完成對(duì)數(shù)據(jù)值的傳遞。一個(gè)學(xué)生對(duì)一
