培养和选拔德才兼备的年轻干部是高校改革和发展的重要保证。做好这项工作，必须转变观念，严格把握基本素质要求，健全用人机制，加强教育管理。     

牡丹与寒梅:以两种花卉阐释唐宋士人的差异

在中国古代,历来有花卉鸟兽抒情明志的传统。在特定历史时期中,某种自然物象同特定的情感和意义之间建立了相对稳固的关系,经过社会的认同,物象便转化为人的情感符号而失去了自身客观性质的特征而成为时代的一种标志。牡丹与寒梅就是唐宋两代士人给予充分观照的审美对象,前者艳绚丽、神采外放,代表了唐代建功立业、开张扬厉的时代精神;后者瞿瘦淡雅,外枯中膏,可与宋人淡泊收敛,质朴深微的心态相契合。唐人爱牡丹,宋人重寒梅,从两种花卉的分析中,可对唐宋的时代精神加以阐释。     

快乐、广义消费与和谐社会模式的建构

快乐是人类经济社会发展惟一有惊天动地性的终极目的。而满足人类快乐需要的不仅是人类创造的国民财富，自然环境中的蓝天白云、青山绿水同样构成人类广义消费的基础内容，成为人类无上快乐的源泉。因此，广大科技工作者应确立科学发展观，在失去科学技术进步、实话国家重大工程与技术项目过程中，关注、构造人与自然和谐发展的经济社会模式。这对全面建设小康社会、实现人类快乐具有深远的意义。

Linearized and rational approximation method for solving non‐linear Burgers' equation

A new numerical method called linearized and rational approximation method is presented to solve non‐linear evolution equations. The utility of the method is demonstrated for the case of differentiation of functions involving steep gradients. The solution of Burgers' equation is presented to illustrate the effectiveness of the technique for the solution of non‐linear evolution equations exhibiting nearly discontinuous solutions.

Damage and fracture evaluation of granular composite materials by digital image correlation method

This paper presents the applications of digital image correlation technique to the mesoscopic damage and fracture study of some granular based composite materials including steelfiber reinforced concrete, sandstone and crystal-polymer composite. The deformation fields of the composite materials resulted from stress localization were obtained by the correlation computation of the surface images with loading steps and thus the related damage prediction and fracture parameters were evaluated. The correlation searching could be performed either directly based on the gray levels of the digital images or from the wavelet transform (WT) coefficients of the transform spectrum. The latter was developed by the authors and showed higher resolution and sensitivity to the singularity detection. Because the displacement components came from the rough surfaces of the composite materials without any coats of gratings or fringes of optical interferometry, both surface profiles and the deformation fields of the composites were visualized which was helpful to compare each other to analyze the damage of those heterogeneous materials.
