英文摘要：

In this paper,the strong smoothness and LwS of Banach spaces are studied,and proved that the LwS spaces is strong smooth spaces and obtained some results and necessary and sufficient conditions related with them. At the same time,the weak exposed points and weak denting points of t3anach spaces are studied, and give the characteristic descriptions of strong smoothness, weak exposed points and weak den- ting points of Banach spaces. Also,we obtained the some properties of strongly smooth Banach spaces.
