DDL型叶片结构与工艺设计(中文3100字,英文2200字)
能源是经济和社会发展的重要物质基础。社会工业化以来,世界能源消费剧增,煤炭、石油、天然气等化石能源资源消耗迅速,生态环境不断恶化,特别是温室气体排放导致日益严峻的全球气候变化,人类社会的可持续发展受到严重威胁。随着人类社会的发展、科技的进步以及日益严重的资源和环境问题的挑战,世界能源结构开始经历第三次大的变革,即从煤炭、石油、天然气为主的能源系统,开始转向以可再生能源为基础的能源系统。

Energy is an important material foundation for economic and social development. Since the industrialization of society, world soaring energy consumption, coal, oil, natural gas and other fossil energy resources consumption rapidly, ecological environment is deteriorating, especially greenhouse gas emissions, leading to increasingly serious global climate change, sustainable development of human society by the Yan Zhongwei coerce. With the development of human society, the progress of science and technology and the increasingly serious resources and environmental problems and challenges, the world energy structure began to experience the third major changes, namely energy system mainly from coal, oil, natural gas, began to shift to renewable energy source system based.
