日本古代女性王权的产生及其文化生态

在公元1、2世纪至8世纪日本古代国家的形成过程中,曾经出现过多位女性登上王权宝座。她们的出现对于稳定社会政治,推动国家的体制、制度建设,繁荣文化与物质生活等发挥了不可替代的作用,在日本古代社会发展史中具有重要影响。拟通过日本古代女性王权的出现及其作用分析其历史、社会和政治背景,由此从一个侧面揭示日本女性与日本文化之间的内在联系。     

Atomic packing and short-to-medium range order evolution of Zr-Pd metallic glass

A larger-scale Zr₇₀Pd₃₀ alloy system has been simulated using molecular dynamics (MD) to investigate structure evolution in Zr₇₀Pd₃₀ metallic glass. The simulated pair distribution function of Zr₇₀Pd₃₀ metallic glass agrees well with the experimental results. Voronoi polyhedron analysis indicates that the icosahedra are not randomly distributed in space, but form characteristic intercrossed icosahedral clusters with medium-range order. Intercrossed icosahedral clusters are the dominant local configurations in Zr₇₀Pd₃₀ metallic glass and probably cause the quasicrystalline phase discovered in Zr₇₀Pd₃₀ metallic glass.

传统文化在包装设计中的作用

我国传统文化与包装设计都具有历史性,它们见证了一个民族的发展,也推动着一个民族的进步.无论在时间上还是在空间上,传统文化和包装设计都是同步的,与其说是传统文化影响了包装设计,还不如说包装设计就是传统文化的载体、舞台;传统文化是包装设计的灵魂.两者相互依存,不断地升华,不断地完美,展示了我国传统文化与现代设计相结合的独特魅力.

Ancient DNA sequences of rice from the low Yangtze reveal significant genotypic divergence

Rice (Oryza sativa) was first domesticated in the lower and middle Yangtze regions of China, and rice remains have been found in many Chinese archaeological sites. Until now, only phenotypic archeobotanical evidence, such as the spikelet bases of ancient grains, has been used to speculate on the domestication process and domestication rate of rice. In this study, we sequenced 4 genomic segments from rice remains in Tianluoshan, a site of the local Hemudu Neolithic culture in the low Yangtze and two other archaeological sites (~2400 and 1200 BC, respectively). We compared our sequences with those of the current domesticated and wild rice (O. rufipogon) populations. At least two genotypes were found in the remains from each site, suggesting a heterozygotic state of the rice seeds. One ancient genotype was not found in the current domesticated population and might have been lost. The rice remains belonged to the japonica group, and most if not all were japonica-type, suggesting that the remains might be at an early stage of indica-japonica divergence or an indica-japonica mixture. We also identified sequences with significant similarity to those from species of Sapindales, Zygophyllales, and Brassicales, which is consistent with the identification of other plant remains in the Tianluoshan site and the common rice field weeds such as mustards in southern China.     

GFRP加固带壁柱砖墙抗剪面积的简化计算

通过1片未加固带壁柱砖墙和9片玻璃纤维增强复合材料(GFRP)加固带壁柱砖墙的抗震性能试验,分析带壁柱墙体中壁柱对墙体抗剪承载力的影响,并提出壁柱影响系数.从等效抗侧移刚度入手,推导出壁柱影响系数最大值的计算表达式;运用壁柱隔离法,推导出壁柱影响系数的最小值计算表达式,并结合壁柱的开洞损伤情况,给出壁柱影响系数的统一表达式,从而简化了计算.最后,通过试验验证该系数提出的合理性.
