“一带一路”背景下中国少数民族艺术计划平台建设分析

在“一带一路”背景下,对中国民族文化宫文物进行了数字化整理,并构建了一个可以包容中国各民族文化艺术品的开放性平台。实现了民族文化平面艺术品的超分辨率采集及可视化,采用超分辨率平面艺术品分布式存储和切片技术,以及民族文化非平面艺术品的3D模型展示等技术,实现技术较高、开放性较好的中国少数民族艺术平台,为宝贵的中国少数民族文化艺术提供载体,使得这些艺术品以数字化方式高质量留存,保护和传承民族文化。

Study on the Resistance of Marine Silica -fume Concrete in Both Frost- thaw Cycles and Chloride Penetration and its Pore Structure

A study was made from both macro and micro aspects into the resistance in frost - thaw cycles and chloride penetration of silica - fume concrete by simulating the characteristics of the marine environment and using the R -value evaluation method, MIP and SEM experiments. The results show that the composite use of silica fume and air - entraining agent with an adequate mixing amount can increase substantially the comprehensive property of concrete in resisting frost - thaw cycles and chloride penetration. After concrete is under frost and thaw cycles by the erosion of seawater, the levels of the most probable pore radius and total porosity have a certain law of varying with the level of R - value, among which an obvious relation of correspondence in a inverse proportion exists. The concrete mixed with silica fume has a poor ability of SO4^2- penetration resistance. The amount and types of superficial and internal corrosive products can reflect the reason of difference in concrete R - value, that is, when the R - value is high, the amount and types of products. MIP and SEM valuation method. superficial corrosive products are more than that of internal corrosive micro analytical results can prove the macro conclusion of R - value evaluation method.
