The obtained reinforced phases of Al-Ti-C composition have high specific Surface due to peculiarities of explosive mechanical and chemical syntheses. It increases the uniformity of their distribution in a matrix melt during the mixing process and also increases properties of castle composite materials.展开更多

The article first discusses thetheoretical issues of early art production in China, mainly taking Mr. Dong Xuewen’s views as an example. Second,scholars have their own views on the discussion of the unbalanced development of art production and materialproduction in the 1970s and 1980s. Third, this article uses the art production theory to construct the contemporaryliterary art form, and raises the art production theory to the essentialism to discuss the art production theory and thereflection theory. Fourth, the relationship between art production and art consumption is in large-scalecomprehensive systematic research.展开更多
