It is well-known that one key issue of solving the Helmholtz equation using finite element method (FEM) is the accuracy deterioration in the solution with increasing wave number due to the ‘‘numerical dispersion error”. Such a numerical dispersion er
氮化反应机理及在材料科学中的应用，孙长庆，郑伟涛，This report presents consistent insight into the mechanism behind the unusual behavior of nitride compounds from the perspective of tetrahedron bond formation and its consequence o
氧氮碳在固体表面四面体成键过程中的电子极化和转移，孙长庆，，In order to gain improved understanding of the kinetics and dynamics of C, N, and O reaction with a solid surface, it is essential to focus on the reaction from the perspectives of
氧原子在金属表面法向迁移机理：四面体键切换重构，孙长庆，，The obsercved O-floating or diffusing at metal surfaces are attributed to the processed of tetrahedron bond switching under a certain conditions.
氮氧添加对纳米固体功函数的调制，孙长庆，郑伟涛，A model is presented towards measures lowering the work function for high-efficiency electron emission. It is suggested that an oxide or nitride tetrahedron formation creates nonbo
This paper presents a new morphing method based on the “as-rigid-as-possible” approach. Unlike the original as-rigid-as-possible method, we avoid the need to construct a consistent tetrahedral mesh, but instead require a consistent triang
In the measurement of automobile body-in-white, it has been widely studied to position the two-dimensional (2D) visual sensors with high precision. In this paper a graphic positioning method is proposed, a hollow tetrahedron is used for a positioning
