【正文】 s Liaoning province, decades ago. The solider gave the old man a handmade saddle when they bid farewell. The story inspired Nasun to write Carved Saddle, a song that later became one of his most popular numbers. Now, every year, Nasun recruits young singers and dancers for the troupe. The troupe has also designed a new repertoire, which is mostly based on the daily lives of Mongolian people, especially the lives of nomadic families, and has bined contemporary musical elements with folk songs of the region. Haimu, a 25yearold khoomei (a local variant of overtone singing) singer, joined the troupe three years ago. Along with a sixmember band, he performs fast songs and soft ones that he writes－all while playing the horsehead fiddle.Although I learned the piano since childhood and grew up listening to various kinds of music, to me, the folk music of Inner Mongolia is the root, he says. Performing in remote villages is pleasant. I feel at home on the boundless grasslands, and the warm people there make me feel fulfilled. The first round of spring auction season in Beijing ended last week, but it failed to create much spring in the art market. Although two pieces of Chinese painting fetched more than 100 million yuan, the decline in trading volume and sale rate showed a downturn this year. In the “Grand View: Chinese Painting Highlight” session at China Guardian 2015 spring auctions, Pan Tianshou’s representative work Eagle, Rock and Flora hit a record auction price of 279 million yuan, while Li Keran’s masterwork Jinggang Mountain fetched million yuan, an unexpected high in recent years. However, the trading volume fells to billion yuan from billion yuan in the same period the year before. The Huangchen 2015 Spring Auctions, which recorded million yuan in total sales, experienced the same. The section number went down to 5 from 12 pared to last year. According to expert Shao Jianwu, the art market did not attract much excitement this year due to the booming stock market and the persistent problems of forgery and fake deals. The two pieces of Chinese painting notched up high price this spring due to their own value not due to a revival in the market. The successful transaction of two works with a hammer price of more than 100 million yuan once again confirms that valuable and rare works of high quality always earn the longlasting high price. Chinese painting and calligraphy is still the pillar of the market. However, the overall sales rate has dropped slightly, which reflects the demand for the ordinary auction goods has weakened,” said the president of China Guardian’s Hu Yanyan. Besides, the entry of new buyers also makes certain changes to the direction of purchasing. In a word, the overall market trend is very unpredictable. Although China Guardian 2015 Spring Auctions has achieved remarkable results, it does not mean that the market has walked out of the predicament. We still have to wait for the big economic boom to invigorate the art market.” Even so, the hot pursuit of some special items appeared this spring. A special session of China Guardian Spring Auctions titled “Fine Gilt—Bronze Buddhist Images” achieved a great deal with total sales volume of million yuan and 92 percent sale rate. The 5th Shamar Rinpoche Statue from 1617th century of Tibet was sold for million yuan. The Beijing Chengxuan Auctions featured almost 2,800 items of coins and stamps in three sessions with good sale rate. The Huachen Auctions also set a special session of photographs under the condition of largescale decline of auction sessions. There was a palpable dull thud of disappointment that acpanied the return of the imperial entourage of Zhen Huan to her homeland. It followed a couple years of hushed excitement as Chinese fans were fed tidbits about their proud concubine who was supposed to conquer the high ground of the North American market. Zhen Huan is, of course, the title character of The Legend of Zhen Huan, a 2011 television series that swept China off its feet and later took other Asian countries by storm. Two years ago, it was reported that HBO, a premium cable service headquartered in the United States, was going to air it in North America after some modification. Now, a condensed version that provides English subtitles but no dubbing has finally been made available on Ne。s Poly Theater. Their show, titled Ulan Muqir on the Grassland, depicted the history and development of the art troupe.

總之，當(dāng)今網(wǎng)絡(luò)技術(shù)日新月異、高速發(fā)展，為了適應(yīng)這種變化，本系統(tǒng)還需要各個(gè)方面的努力來(lái)使它不斷完善。
但是由于畢業(yè)設(shè)計(jì)時(shí)間的關(guān)系，該系統(tǒng)還有許多不足之處，比如用戶界面不夠美觀，程序比較煩瑣等多方面問(wèn)題。

（1）根據(jù)各個(gè)模塊的功能需要，設(shè)計(jì)編寫(xiě)了功能完善的JavaBean組件，使得整個(gè)系統(tǒng)界面和功能的設(shè)計(jì)思路非常清晰，而且易于維護(hù)和擴(kuò)展。該系統(tǒng)可以根據(jù)需求對(duì)功能進(jìn)行擴(kuò)展和完善。服務(wù)器端的系統(tǒng)活動(dòng)圖也做了簡(jiǎn)單的設(shè)計(jì)，還有待于完善。圖613 “允許收取郵件”用例活動(dòng)圖以上即為本系統(tǒng)的設(shè)計(jì)與實(shí)現(xiàn)。圖611 用戶修改資料界面 服務(wù)器端的系統(tǒng)活動(dòng)圖設(shè)計(jì)（1）服務(wù)器端“允許發(fā)送郵件”的用例活動(dòng)圖，如圖612所示。 用戶修改個(gè)人資料管理模塊設(shè)計(jì)與實(shí)現(xiàn)此項(xiàng)管理是能讓各個(gè)用戶修改自己的信息，信息內(nèi)容和注冊(cè)用戶信息基本一致。在此類(lèi)函數(shù)中，首先對(duì)郵件表根據(jù)發(fā)件箱字段的條件issend=0和delS=0進(jìn)行SELECT操作，把郵件信息存放到Vector對(duì)象smsVector中，然后返回。在發(fā)件箱中可以查看沒(méi)有發(fā)送的郵件。 查看郵件詳細(xì)內(nèi)容界面設(shè)計(jì)草稿箱、發(fā)件箱和垃圾箱要實(shí)現(xiàn)的功能，也都是先顯示在一定狀態(tài)下的所有郵件的列表中，功能實(shí)現(xiàn)過(guò)程與收件箱類(lèi)似，這里不再一一重復(fù)介紹。圖610用戶收件箱管理界面，單擊各個(gè)發(fā)件人的用戶名，則可以查看此用戶的個(gè)人信息，此界面和管理員用戶管理中所設(shè)計(jì)的用戶基本信息界面一樣。用戶對(duì)收件箱進(jìn)行清理，會(huì)刪除所有不用的郵件，所以要提供“刪除收件”和“清空收件箱”按鈕，在郵件列表的每一條郵件后面都提供有復(fù)選框，用來(lái)選擇所要?jiǎng)h除的郵件。和平時(shí)所用的郵箱的收件箱一樣，此界面為所有郵件的列表信息，具體顯示發(fā)件人、主題(郵件的標(biāo)題)、日期和大小等內(nèi)容。如果是保存，則把所編寫(xiě)的郵件保存在發(fā)件箱中；如果是發(fā)送，則可在已發(fā)郵件找到所發(fā)送的郵件。（2）檢查收件人在系統(tǒng)中是否存在，即檢驗(yàn)收件人的合法性。在執(zhí)行發(fā)送郵件之前，需要檢驗(yàn)新輸入的收件人是否在系統(tǒng)中存在，一旦存在則不允許發(fā)送，然后再根據(jù)表mes
