李秀成地方建设的新思维及其影响

李秀成地方建设的新思维,其主旨在于努力改变太平天国的征服者形象,强调社会秩序的恢复和与地方民众特别是士绅阶层的社会合作。这种新思维被他的部分部将效法,太平天国的地方建设出现了与前期迥然不同的新气象。     

池莉小说中的女性柔情

从女作家的性别出发,众多评论性的文章或者认定池莉从事的是中性写作,或者就池莉的所谓女权主义大作文章。本文拟撇开这些评论视角,从池莉重客观、重体验的写作特色以及传统的“阳刚阴柔”的审美认知角度简析一下池莉小说中的女性柔情。     

论李煜词几类常见意象的审美意蕴

"意象"是创作主体和客体相融合的产物,是客体中寄寓了主体的主观情思的具体形象,是客体经过主体的艺术物化所产生的结果。李煜词中的意象运用丰富多彩,其中有"愁"意象、"梦"意象、"月"意象,这些意象的运用,有助于我们对李煜的词作深一层的了解。     

李白诗句新解

本文通过对李白诗句＂古来圣贤皆寂寞,惟有饮者留其名＂中＂圣贤＂二字的考证,认为传统的仅限于字面意义上的理解甚为不妥,继而提出自己的新见解。     

"箕裘"新解

"箕裘"典出<礼记·学记>.长期以来,学术界多从唐孔颖达疏之说,将"箕裘"之"裘"错作"皮衣"、"皮袍"解. 文章根据文献资料和冶金史研究所得,对这一典故作了新的诠释.     

素环上导子的线性组合

设R是中心为Z,扩张形心为C的素环,证明了:设,(x),g(x),h(x)为R上非零导子,若af(x) bg(x) ch(x)亦是R上导子,且在R上交换,则f(x)=λ1x ζ1(x),g(x)=λ2x ζ2(x),h(x)=λ3x ζ3(x),其中λ1,λ2,λ 3∈C,ζ1,ζ2,ζ3为R一C的加性映射.     

Numerical investigation on heat transfer characterization of liquid lithium metal in pipe

Liquid Li metal is a promising nuclear reactor coolant; however, relevant research regarding its heat transfer characteristics remains insufficient. In this study, a steady-state two-dimensional mathematical model is established to describe the heat transfer process of liquid Li in a straight pipe. A numerical analysis is conducted to investigate the effects of inlet velocity, inlet temperature, and wall heat flux on heat transfer in liquid Li. The results indicate the advantage of using liquid Li for improving heat transfer at high inlet temperatures (> 1000 K) compared with using liquid sodium and lead–bismuth eutectic. Considering the mechanism of the outlet radial heat flow model, the ratio of turbulent to molecular diffusion coefficients presents a parabolic distribution along the radius of the pipe. Increasing the inlet velocity, decreasing the inlet temperature, and decreasing the wall heat flux can effectively weaken the dominant role of molecular heat transfer owing to the low Prandtl number of liquid Li. The heat transfer of liquid Li is investigated comprehensively in this study, and the results provide a basis for the practical application of liquid Li as a promising coolant.
