This article analyses problems existing in calculating the speed of average development with horizontal method, and suggests using weighting method and deduces its formula.

Application of level set method in microstructure optimization of multiphase material;

After studying the level set method and its applications to image processing, we concentrate on discussing the inpainting model.

A new method based on the level set method was proposed for simulation the three-phase flow problems,with which the gas bubble behavior in the slag-steel interface was calculated,the infuence of bubble size on the bubble deformation during the floating process was analyzed,and its impact on the fluid velocity in the steel-slag interface was calculated.

Size of Government,Rule of Law,and the Development of Services Sector;

This paper examines the impact of China s rule of law on the development of services sector by using the panel data of different regions in China between 1991 and 2001.

The backwardness of services sector is closely related to poor rule of law,the catching-up strategy,the political tournament system and size of government.

According to the considerable revision of the legitimate defence system in the new Criminal Law,this paper puts forward the following suggestions:It s necessary to emancipate the mind,renew the concept and establish a new concept of legitimate defence;It s essential to strengthen education and supervision and enhance the judicial level o.

Finally, the deformation of horizontal flange in stepped welding casing is controlled by controlling welding procedure and adopting anti-deformation measure.
