Developed from China＇s nuclear R＆D system and manufacturing capability, as well as APIO00 technology introduction and assimilation, CAP1400 is an advanced large passive nuclear power plant with independent intellectual property rights. By discussing the top design principle, main performance objectives, general parameters, safety design, and important improvements in safety, economy, and oth- er advanced features, this paper reveals the technology innovation and competitiveness of CAP1400 as an internationally promising Gen-IIl PWR model. Moreover, the R＆D of CAP1400 has greatly promoted China＇s domestic nuclear power industry from the Gen-II to the Gen-III level.展开更多

In order to study the effect ofb on the wettability of the rough surface, the effects of apparent contact angle （CA） and sliding angle （a） of the droplet on the rough surface were measured with the contact angle meter. The results show that the experimental values of CA well agree with the classical wetting theory and a decreases with the increase of b. Two drop shapes exist on the samples＇ surface, corresponding to the Cassie state and the Wenzel state respectively. The contact state in which a drop would settle depends typically on the size of b. On the role of gravitation, the irreversible transition of a drop from Cassie state to Wenzel state should occur at a certain space of the square pillars. Since the transition has implications on the application of super-hydrophobic rough surfaces, theoretically, the prediction of wetting state transition on square pillar array micro-structured surfaces provides an intuitionistic guidance for the design of steady superhydrophobic surfaces.展开更多

Based on the situation of Far East Cable Company, it analyzes the significance of strengthening the protection of proprietary IPRs and implementing a strategy for technology standards and then discusses the actual work and future arrangement of proprietary IPRs and technology standard strategies. It points out that the enhancement of proprietary IPRs protection and implementation of technology standard strategies is the only way for enterprises to remain competitive.展开更多
