The interrelationship between several basic categories in fuzzy topology is made clear in terms of co-tower extension of topological constructs. It is shown that for ever completely distributive lattice L,the the category of L-fuzzifying topological spaces is isomorphic to the cotower extension of the category of topological spaces, and it can be embbedded in the category of L-topological spaces as a simultaneously reflective and coreflective subcategory.

目前我国东部的石油勘探工作已进入精细勘探阶段,如何确定陆相地层中薄储层的空间展布规律及其性质已成为一个亟待解决的问题,由于我国东部的绝大多数中、新生代陆相含油盆地大都以薄层砂、泥岩沉积为主,夹有少量薄层碳酸盐岩、页岩及膏盐层,地层岩性和厚度横向变化均较大,而且这些地层的厚度远远低于常规地震勘探的垂向分辨率,因此,从理论上研究沙泥岩薄互层地震反射特征、薄互层组内的单层厚度、子结构厚度、互层组内层数、入射子波类型、主频、采样率等各种因素对反射波特征的影响,将对我们定性或定量求取薄互层组中各单层厚度或薄层组的厚度、预测薄储层的空间展布规律有一定的理论和现实意义。
