Alcohol-based coating was developed with brown alumina powder as refractory aggregate, phenolic resin as composite binder, the lithium base bentonite as suspending agent. Through the process testing and practical production verification, the coating developed was suitable for large-scale production of high manganese steel. © 2015, Journal Office of Special Casting and Nonferrous Alloys.

This paper investigates the flux distributions of the electron photo-detached from H- ion localized in a gradient electric field. In contrast with the photodetachment in the uniform electric field [Phys. Rev. A 40 (1989) 4983], where only two electron trajectories interfere at each given point on a detector, for the photodetachment in a gradient electric field, the electrons waves can travel along multiple paths from the negative ion to a given point on the detector plane, which makes the electron flux distributions on the detector plane become much complex. Using the semi-classical theory, we put forward a formula for calculating the electron flux. Our calculation results suggest that the electron flux distributions on a given detector plane is not only related to the propagation time of the detached electron, but also related to the detached electron's energy. With the increase of the detached electron's energy, the oscillating region in the electron flux distributions becomes enlarged and the oscillating structure in the flux distributions becomes much more complicated. This study will guide future experiment research on the photodetachment microscopy of the negative ions in the presence of non-uniform external fields. © 2015 Chinese Physical Society and IOP Publishing Ltd.

With the rapid development of science and technology, the process of economic globalization has been accelerated, intellectual property competition heats up, which becomes the key to the development of enterprise management, competition and restricting factors in the modern economic environment. Enterprise must take both with international laws and regulations system, and can effectively protect the interests of the market of intellectual property management strategy for long-term development. Through summing up chinese enterprise intellectual property management present situation, in accordance with the national “standard of enterprise intellectual property management” of the specific requirements, this paper builds the whole process of enterprise operation and management model of intellectual property standardization management, to establish a scientific management processes and system for enterprise management framework to provide the reference. © Tang Libo; Licensee Bentham Open.

Quantum chemical calculations have been performed for the complexes Li 3OCCX-Y (X = Cl, Br, H; Y = NH3, H2O, H 2S) and Li3OCN-X′Y′ (X′Y′ = ClF, BrCl, BrF, HF) to study the role of superalkalis in hydrogen and halogen bonds. The results show that the presence of an Li3O cluster in a Lewis acid weakens its acidity, while its presence in a Lewis base enhances its basicity. Furthermore, the latter effect is more prominent than the former one, and the presence of an Na3O cluster causes an even greater effect than Li3O. The strengths of hydrogen and halogen bonds were analyzed using molecular electrostatic potentials. The contributions of superalkalis to the strength of hydrogen and halogen bonds were elucidated by analyzing differences in electron density. © 2012 Springer-Verlag Berlin Heidelberg. Source
