论北宋词的女性化特征演进史

本文在阐释了词的女性化特征的前提下,主要描述了北宋词的女性化特征演进历程。笔者先对北宋词史链条上的每一个词人的风格进行个案梳理,然后用史学模式和史学思维重新构建北宋词女性化特征发展流变的整体框架。柳永、东坡、美成等的个案研究意在梳理出词人之间在词风上互相传承的关系,以此归结出词的本质属性--女性化特征的演进过程。

The Numerical Simulation of the Spherical Segment Liner Forming the EFP and Its Optimization Design

By using ANSYS / LS-DYNA software to make the numerical simulation of the process about Spherical Segment Liners forming the EFP,this paper focuses on analysis of shaped charge liner thickness and the charge of the aspect ratio L / D of the EFP forming impact.By looking at the EFP molding process graph and analyzing EFP node speed curve it is obtained that EFP molding process is consistent with the theoretical analysis.With shaped charge liner thickness increases,the rate of EFP constant decreases,the head is more and more blunt.With the charge of the aspect ratio L / D increases,EFP＇s speed has also increased,and after L / D is 1.75 the speed growth is slower.To get the optimal design parameters of charge with a radius of 6.5cm of the EFP Warhead,shaped charge liner thickness is 0.4cm,charge of the aspect ratio L / D is 1.5.
