研究者所關注的問題是選擇新的體系進行研究,以期得到性能更好的鋰離子導體材料,這也正是本論文的基本出發點;復合離子導體中第二相的加入改善了基質的界面結構和導電機制,不僅可以提高基質材料的電導率,還可以在一定程度上改善材料的其它性能,如燒結性能、脆性和機械強度等。因此復合材料的研究是離子導體一個有廣闊前景的發展方向;合成鋰離子導體,特別是成分復雜的體系以傳統的固相合成法為主,但這種方法需要較高的溫度,容易引起鋰的揮發,從而造成產物組成的偏移,而且不易得到顯微結構均勻的材料。The bank vulnerability has been matter of concern in the works of economic historian and the institutional school. the classical economists such as marx, marshall, keynes mainly describe and analyze bank crisis from the angle of economic cycle, minsky and kindleberger introduces the behavior factor of microscopic main body into the analysis of bank vulnerability. the development of the game theory and the information economics lay a solid foundation for stiglitz and weiss ' s study about bank vulnerability
