摘要：Solid oxide fuel cells(SOFCs)have attracted a great deal of interest because they have the highest efficiency without using any noble metal as catalysts among all the fuel cell ***,traditional SOFCs suffer from having a higher volume,current leakage,complex connections,and difficulty in gas *** solve these problems,Rolls-Royce has fabricated a simple design by stacking cells in series on an insulating porous support,resulting in the tubular segmented-in-series solid oxide fuel cells(SIS-SOFCs),which achieved higher output *** work systematically reviews recent advances in the structures,preparation methods,perform-ances,and stability of tubular SIS-SOFCs in experimental and numerical ***,the challenges and future development of tubular SIS-SOFCs are also *** findings of this work can help guide the direction and inspire innovation of future development in this field.

摘要：回顾中国铝工业使用进口铝土矿的起因和发展，迄今已经达到每年4000～5000万吨的巨大规模，进口国家、地区形成多元化格局。关于各种类型铝土矿的特征和来源、出口方的各类诉求、矿石价格的相关因素等，文中都有涉及。进口矿主要是三水铝石，其工艺溶出特性与国内的一水硬铝石有很大区别，不能简单地用一般的铝硅比去评价。本文基于溶出过程原理，重点分析了进口铝土矿的矿石单耗、碱消耗，明确了它们在氧化铝生产成本中占有的显著地位。基于这样的方法途径去认识进口铝土矿，才能确保经营效益的提升。

摘要：指出了传统村落景观是社会的经济和自然达到协调统一而呈现出的和谐的生态人居环境。通过对绍兴传统村落的考察,研究了其村落布局,建筑和庭院空间,植物景观,水系景观要素。且在村落选址布局景观营造过程中,融入宗族文化,体现了绍兴"天人合一、耕读写意、依山傍水"的村落景观特征。
