The Chinese role which China acted in Africa could be a kind of mode in supporting the developing country. Those are updating and building the basal establishment of the Africa country roundly, building the concessionary area of economy, impulsing the development of scopes in Afric economy which had been neglected by the west world , encouraging Chinese company to invest in the danger location, believing the Afric country's ability and supporting them institute the tactic of development by themselves.

中国当前在非洲扮演的角色，也许会成为支持第三世界发展的一种模式：全面更新非洲国家的基础设施建设；在当地设立经济特区；推动非洲经济中被西方忽视的领域的发展；鼓励中国公司在高风险的地区投资；相信非洲国家的能力，支持它们自己制定发展战略。

Beverly Joubert,非洲,狮子 A hundred years ago there were 450,000 lions in Africa,When we started our work in the early 1980s,research told us ther were only about 50,000 lions.

一百年前在非洲有45万只狮子，可20世纪80年代之后，研究告诉我们，只有5万只狮子了

Africa is the antecedence and the politicians will altercate abbreviation the debt burden, catastrophe barter regulations which put the continent's abridgement at a disadvantage, and giving added aid.

政治家们将讨论减少非洲的债务负担，结束那些束缚非洲经济发展的贸易规则，而且要给予非洲更多的援助。马克·多伊勒是一位在非洲工作了多年的记者。

The studies was proceeded on the the supercritical CO2 extraction technique of rotenone from Tephrosia vogelii. The extraction influences of technology conditions were systematically groped, The research results were listed as follows:1 The analysis method applied in this paper has been proved to be suitable to technology research of the studies on the SC-CO: extraction technique of rotenone from Tephrosia vogelii. 3 indexes, extraction ratio of rotenone. extraction ratio of total compounds and rotenone content percent in total compounds weight, were carried out with HPLC quantitatively determination combined with the sample weight loss after extraction. With these 3 indexes. The extraction influences of technology conditions were evaluated by synthesis. Then the best technology conditions were ascertained for different extraction aims.2 The pretreatment of rough material should be needed before extraction. Comminuting the material to 0.28mm size is most fit to SC-CO: extraction.3 Firstly static extracting 20 min then turn to dynamic doing is the better extraction mode than other ones.4 The orthogonal experiment was conduct with 3 factors and 5 levers.

本论文通过对非洲山毛豆SC-CO_2萃取中影响萃取效果的工艺条件的研究，初步得出如下结果：(1)本论文中所采用的萃取效果评价方法适宜于非洲山毛豆中鱼藤酮的超临界流体萃取技术研究，该方法具体为：HPLC定量分析非洲山毛豆SC-CO_2萃取物中的鱼藤酮含量，再结合萃取前后处理样品的重量损失，得出鱼藤酮萃取率、萃取所得粗物质萃取率和粗物质中鱼藤酮含量三个参数，以此三个指标综合评价萃取条件对萃取效果的影响；(2)通过对原料粒度对萃取效果影响的研究，结果表明SC-CO_2萃取非洲山毛豆复叶中的鱼藤酮，原料粉碎成30目粒度叶粉时萃取效果较好；(3)通过对萃取方式与萃取效果之间关系的研究，结果表明SC-CO_2萃取非洲山毛豆中鱼藤酮应采用先静态后动态的萃取方式，静态萃取时间为20min；(4)通过温度、压力和CO_2流量三因素五水平的正交试验，结果表明温度是最主要的影响因素，压力因素对鱼藤酮萃取率的影响程度高于CO_2流量，而对于粗物质萃取率和粗物质中鱼藤酮含量CO_2流量因素高于压力。

Meanwhile, Achebe also introspects the dark side of African culture, reflects on the outlet for Africa development and argues that only by persisting in their national culture, winning national dignity and absorbing the essence of western civilization can a new Africa be built.

同时，在重塑非洲形象的同时阿切比也质疑了非洲文化，思考了非洲发展的出路，最终证实只有坚持自己的民族文化，获得民族尊严，并吸收西方文明的精髓才能构建一个新非洲。来源：18ABC论文网www.abclunwen.com

When traveling in Africa, sometimes I was embraced by heavenly natural scenes, and other time the simple and honest custom caught my eye balls. Once and again . I felt the heartbeat of the continent from ancient African drumbeats, in the exciting racecourse and in the crowded streets.

行走在非洲大地，我从最初沉醉于天堂般旖旎的自然风光中逐渐被非洲敦厚的风土人情所吸引，在古老苍凉的非洲鼓声中，在人潮涌动，烈马奋蹄的赛马场上，在街市的人流交汇中，我一遍又一遍地聆听着非洲的心跳。

The Scramble for Africa 15 对非洲的掠夺 At the beginning of the 19th century British possessions were confined to slave trading posts on the west coast.

At the turn of the century, as the fast development of economic globalization, Africa is confronting with tremendous challenges in political, economical and social fields. Africa needs a continental organization with higher authority than the Organization of African Unity.

世纪之交，随着经济全球化的深入发展，非洲在政治、经济和社会等各个领域都面临巨大挑战，非洲需要一个比非洲统一组织具有更高权威的全洲性组织。2002年7月9日，非洲联盟应运而生，它的诞生使非洲数代领导人的非洲统一理想变为现实。

Forty-four years ago today, the Organization of African Unity was established, which was a historic step taken by African countries and peoples for liberation, solidarity and unity . The 25th of May thus became a special day in the annals of Africa. The African Union formally succeeded the OAU in 2002, shouldering the important responsibility of maintaining peace and stability and achieving development and renaissance in Africa. African countries entered a new stage in their efforts to develop themselves through unity.

44年前的今天，非洲统一组织的成立标志着非洲国家和人民在争取民族解放、促进团结统一的道路上迈出了历史性的一步，5月25日这一天永远载入了非洲的史册。2002年，非洲联盟正式接过非洲统一组织的旗帜，担负起维护非洲和平稳定、实现非洲发展振兴的重任，非洲国家联合自强进入一个新的发展阶段。
