Lignocellulosic biomass represents a renewable resource for the production of biofuels.However,the complexity of lignin-hemicellulose structures,the crystallinity of cellulose and low surface area are major obstacles to the effective utilization of lignocellulose.Dilute-acid hydrolysis is an effective and probably the most commonly pretreatment of lignocellulose,which results in a highly digestible substrate for further enzymatic cellulose hydrolysis with reasonably high sugar yields.However,unexpected side reactions occur unavoidably during the degradation of lignocellulose,which yield several toxic by-products other than glucose and seriously restrict microorganism growth and the production of butanol.

柴油发动机因具有高效可靠的动力性能、良好的经济性而被广泛应用。但柴油车尾气中的污染物带来了严重的环境问题,威胁人类健康。与此同时,各国也根据国情纷纷制定了越来越严格的排放法规。因此,消除柴油车尾气中的污染物刻不容缓。传统的消除柴油车尾气中碳烟颗粒物的方法是采用颗粒物过滤器(DPF),但颗粒物过滤器存在活性涂层易脱落的缺点。针对该问题,本文拟采用剪切流协助的溶胶-凝胶法制备具有三维网格结构的SBA-
氮(N)在水稻产量和品质形成过程中起着关键作用,增施氮肥是水稻获得高产的必要措施之一。氮肥的利用率越高越有利于农业的可持续发展。了解氮素吸收转运及再分配的机理对于提高氮肥的利用率和指导农业上氮肥的施用具有重要意义。已有一些研究表明,氮素营养与细胞分裂素水平和叶片衰老之间有着非常紧密的联系,但是缺氮处理下细胞分裂素对水稻幼苗氮素吸收转运及再分配和叶片衰老的调控机制仍不清楚。本论文以籼稻9311为实验
