Al2O3f/Al2O3 ceramic matrix composites(CMC)are promising candidate materials of blades and combustor liners of future gas turbines in light of their higher temperature capability,higher environmental stability and oxidizing-free capacity[1–3].Nevertheless,grain growth,sintering and creep deformation at high operation temperatures are still serious problems for Al2O3f/Al2O3 ceramic matrix composites,which can lead to a reduction in the strength and damage tolerance[2].Moreover,Al2O3 can be corroded by the high temperature water vapor in combustion environments and yields volatile products,such as Al(OH)3[4].Consequently,environmental barrier coatings(EBCs)are necessary for Al2O3f/Al2O3 ceramic matrix composites,which can protect Al2O3f/Al2O3 CMC from high temperature and flowing combustion gas corrosion and thus increase the high temperature capability and the service life of components.

Study of nitrogen-fixation cell biology has gradually advanced to the study of only one kind of cells in root nodules, such as the infected cell, uninfected cell, cortex cell, from general structure of root nodules now. Some authors even start to study one kind of composition of the above-mentioned cells, for example, cell wall, cytoplasm, dictyosome, microbody and specially cytoplasmic inclusion, etc., because these studies can help us

高考英语全国卷中完形填空占了相当的分值,各省市自命题卷中也大多包含完形填空这一题型,因为完形填空能比较准确地考查考生阅读理解、词汇及语法知识运用等综合能力。它要求考生在选项中选取一个最佳答案,而非唯一正确答案,这就增加了难度,因为往往并不是唯一选项意思契合上下文,也并不一定唯一选项语法恰当。在这种情况下,考生唯有对文章的理解达到一定准确程度,对英语语言有一定驾驭能力,才能够甄选出一个最符合上下文意思、用法最恰当且衔接
