The 21st century is an era of knowledge- economy. In this century, China's agriculture is to transform from traditional pattern to knowledgable,marketable,ecological,intensive,social and modern pattern. The new developing trend indicates that in this century China's agriculture will develop towards genetic ,ecological,white,seaside, urban,tourism,network,aeronautic,precise and high quality. 21世纪是知识经济的时代。在新的世纪里 ,中国农业将实现由传统农业向知识化、市场化、生态化、集约化和社会化的现代农业转变。这一发展新动向表明 ,基因农业、生态农业、白色农业、海洋农业、都市农业、观光旅游农业、网上农业、太空农业、精准农业和优质农业将是 2 1世纪中国农业发展的新趋势 Contemporarily,the world ' s agriculture comes into the times of knowledge agriculture under the force of new technological revolutionary,and it is developing toward the ones of gene,caution,three-color,ecology,sus - tentation,web,space and so on.As a developing country with great agriculture,that how to develop it in our country has become an important issue on economic development.With the speedy advance of knowledge econ - omy,especially after China ' s entry to WTO,knowledge application... Contemporarily,the world ' s agriculture comes into the times of knowledge agriculture under the force of new technological revolutionary,and it is developing toward the ones of gene,caution,three-color,ecology,sus - tentation,web,space and so on.As a developing country with great agriculture,that how to develop it in our country has become an important issue on economic development.With the speedy advance of knowledge econ - omy,especially after China ' s entry to WTO,knowledge application in agriculture has become the objective de - mand and irreversible tendency. 当今世界,在新科技革命的推动下,世界农业步入知识农业时代,正向着基因农业、精细农业、三色农业(包括绿色农业、蓝色农业、白色农业)、生态农业和持续农业、网上农业、太空农业等方向发展。我国作为一个发展中的农业大国,如何发展农业已成为我国经济发展的重要问题。随着知识经济的迅猛发展,特别是我国加入WTO后,农业的知识化已成为我国农业发展的客观要求和必然趋势。 >=The backbone of the modem science and technology-information, biology and material-are experiencing a breakthrough whose important fact is the development of composite material. Composite material is playing an important role in the technology of aeronautics and astronautics. 现代科学技术的三大支柱——信息、生物和材料正孕育着和实现着重大的突破,复合材料的发展正是这种突破的一个重要方面。随着我国航空航天技术的发展,复合材料对航空航天技术的促进有着举足轻重的作用。复合材料中的“复合”这个词表示由两种或多种材料在宏观尺度上组合成的一种有用的材料。它有着长远的使用历史,人们很早就知道把稻草掺入泥中做成泥砖可增加强度;用胶板代替木板不但能提高强度,而且能减少变形;中世纪的剑和盔甲也是用不同材料层合构成的。从60年代末开始,以纤维增强为表征的复合材料进展非常迅速,已在航空航天领域得到了日益广泛应用。由于航空航天事业的发展,人类走出地球以外已经成为当今人们普遍关注的重大问题。它科技含量高,涉及众多领域,要求实现多学科联合与攻关。随着现代科学技术发展和转移,复合材料应用也要进一步扩大,研制适于太空农业发展的复合材料新品系。
