近半个世纪以来,在国外对夹层化合物的研究已引起许多科学工作者的兴趣,由于夹层作用不同于一般的化学反应,对夹层过程、结构及物性展开了广泛的研究。通过综述文章及许多论文刊载情况看,逐渐由化学领域转入物理或材料科学领域,同时在应用方面也作了探索。本文拟对夹层化合物的基本概况及应用作简单介绍。 For nearly half a century, the research on sandwich compounds in foreign countries has attracted the interest of many scientists. Since the interlayer effect is different from the general chemical reaction, the interlayer process, structure and physical properties have been extensively studied. Through the review of articles and many papers published situation, gradually from the field of chemistry into physical or material science, at the same time also made in the application of exploration. This article intends to sandwich the basic profile of compounds and their applications for a brief introduction.
