Some New Views on the Principles of Magnetron Sputtering FANG Kai-ming1,TONG Hong-Hui1,ZHAO Jia-xue1 (1.Southwestern Institute of Physics, Chengdu, 610041, Sichuan, P. R. China) 摘要:In this paper, some common phenomena in magnetron sputtering are freshly analyzed and discussed on the basis of the motion of electrons in non-uniform orthogonal electric and magnetic fields. There exist magnetic......

FIRST ORDER LANGUAGE FOR ENTITY-ROLES MODEL+Pan Jiuhui; Liu Zhimin; Wang Yunyi(Department of Computer Science, Central South University of Technology. Changsha, 410083. China)Abstract:With respect to the mathematical structure supposed by theEntity-Roles Model. a first order (three--valued) logic language is constructured. A world to be modelled can be logically specified in this language......
