魏晋皇帝宗庙祭祖礼制考论

魏晋皇帝宗庙四时祭祖礼制,既有沿袭东汉相关制度之处,也有因时适宜变革、创新之处。由于受经学领域郑玄、王肃两大学派相互辩难、竞长的影响,曹魏皇帝宗庙禘、祫祭礼制最初依据郑玄学说,而后兼采郑玄、王肃学说定制。为兼顾情、礼,东晋自穆帝以后,逐渐实行每三十个月举行一次祭祀的殷祭制度。

The Translatology Process of the Word''''Gaze''''in Chinese Context

With reference to the concept of'cultural studies'and certain modern theories in translation studies,this essay makes a general analysis of the translation and introduction of the'gaze'concept in China.On the basis of this analysis,it explores how this concept spread to China and why,this concept Was explained and rewritten through translation and interpretation in the course of the spread;and what responses and reflections we should bear during the process.     

合理垂直烧结速度的研究

通过考查气流速度的变化研究垂直烧结速度随烧结过程的变化规律。结果表明:垂直烧结速度并非固定不变,而是随着烧结过程的逐步进行发生显著变化;点火保温后,随烧结物理化学反应的进行,燃烧带逐渐形成并变宽且产生过湿现象,导致料层的透气性显著变差,烧结速度显著下降,直至约25 min后过湿层完全消失,透气性变好,烧结速度迅速上升。根据垂直烧结速度变化规律,通过改变负压烧结,进行烧结速度优化实验,结果表明:在保持转鼓强度及成品率基本不变的情况下,将垂直烧结速度由20.08 mm/min提高到21.82 mm/min,利用系数由1.401 t/(m2-h)提高到1.587 t/(m2-h)。     

Electronic Structure and Magnetic Properties of SmCo7-xZrx

The electronic structure and magnetism of SmCo_7-xZr_x alloy are investigated using the spin-polarized MS-X. method. The results show that a few of electrons are transferred to the Sm(5d⁰) orbital due to orbital hybridization between Sm and Co atoms. The exchange interactions between 3d and 5d electrons are more important than the polarization effects of the conductive electrons, thus it is the main reason resulting in the long-range ferromagnetic order in SmCo_7-xZr_x. The Curie temperature of SmCo_7-xZr_x is generally lower than that of corresponding pure Co, which may be explained by the weaker average coupling strength between Co lattices due to some negative couplings mainly occurring of 2e site. The calculated results for the Sm₅Co₃₂Zr₂ cluster may lead to a better understanding of why SmCo_7-xZr_x is stable phase. Since the spin-up DOS peak of d electrons at E_F arises and the bonding of electrons at E_F strengthens with increasing Zr concentration, which results in the internal energy of the system decrease, the stable ferromagnetic order forms in SmCo_7-xZr_x.
