六铝酸盐因其特殊的层状结构具有高温热稳定性;晶格中Al^(3+)可被不同过渡金属和贵金属离子取代,具有活性组分可镶嵌性;镜面层排列疏松,为氧的优先扩散通道;以上结构特质为六铝酸盐在高温涉氧方面的应用奠定了坚实的基础。本综述从六铝... 六铝酸盐因其特殊的层状结构具有高温热稳定性;晶格中Al^(3+)可被不同过渡金属和贵金属离子取代,具有活性组分可镶嵌性;镜面层排列疏松,为氧的优先扩散通道;以上结构特质为六铝酸盐在高温涉氧方面的应用奠定了坚实的基础。本综述从六铝酸盐的结构出发,详细讨论了六铝酸盐的结构类型(磁铅石型和β-Al_2O_3型)和金属取代对其微观结构(尤其是金属化学状态)的影响,并介绍了近年来六铝酸盐在高温涉氧反应,如CH_4催化燃烧、环保领域N_2O消除、航天推进级N_2O分解、甲烷化学链燃烧和重整中的应用,重点关注了六铝酸盐结构与性能的关联,最后对六铝酸盐未来研究方向作出展望。 展开更多

On January 28, 1991, the Chinese Government wrote to the United Nations, offering to host the 1995 Fourth World Conference on Women. In March 1992, the 36th session of the UN Commission on the Status of Women gratefully accepted the invitation of the Chinese government and decided to schedule the conference for September 4-15, 1995, in Beijing. The theme of the conference is to seek equality, development and peace through action. The secondary subjects include issues of employment, education and health. At that time, all the member countries of the United Nations will send the high-level gorernmental delegation to attend the conference. Meanwhile, the Non-Government Organizations Forum will be held as a subsidiary plenary to the conference. The year 1995 marks the 50th anniversary of the founding of the United Nations, the 2Oth anniversary of the UN International Women’s Year and the lOth anniversary of the adoption of the Nairobi Strategy. This conference is an important event in UN women’s affairs 展开更多
