Studies the combustion synthesis of Al Ti TiO 2 system and concludes that, due to its low exothermic nature, a stable combustion wave can be maintained only when the system is ignited at a certain preheating temperature, and coupled with appropriate pseudo HIP process, dense TiAl/Al 2O 3 composites with density as high as 97% of the theoretical value can be produced, and points out. Microstructure observation shows in situ formed Al 2O 3 particles are of an average size smaller than one micron, and the hardness of TiAl matrix is enhanced by introduction of these particles.

年年岁岁花相似 岁岁年年人不同──千古诗坛奇闻故事郭文卿作为本文题目的这两句话，历来被视为名句。这对佳句，原本出自唐代诗人刘希夷《代悲白头翁》一诗中。而作者刘希夷却
去年。我去参加在日本举行的亚洲创新论坛。我提了一个观点：目前亚洲企业在考虑企业发展模式的时候，对于西方依然有着一种崇拜的心态，基本上是把西方的理念直接拷贝过来?至少到目前，整个东方的思维依然在西方的框架之下很难超越，当然。日本也不例外。 我一直认为“以全球应对全球”是一个国家支撑未来的核心能力。恕我直言，因为文化和语言等带来的一些障碍，日本企业在高端管理人才整合方面是滞后于欧美企业的，所以我判断
天不变,道亦不变,对于文学来说也是如此。无论其载体如何在历史的长河中流变,文学所具有的人文情怀是不能舍弃的,所需要的怀抱人道理想,投入自己的生命,以真诚的态度去写人,
你可曾用掌声表达情感过?你可曾用掌声给别人带来安慰过?你可曾用掌声给予他人鼓励过?如果没有,请从现在做起,用发自内心的掌声关怀别人吧。因为,生活需要掌声。我们的祖先可
