丘浚与斯密经济思想之比较分析

本文比较和分析了丘浚和斯密经济思想的相同之处,并运用马克思主义政治经济学的研究方法和分析范式进行了重新审视,对他们经济观点中存在的不足和某些缺陷进行了初步的探讨和考述。这必将有助于正确继承和发展他们经济思想中的科学合理成分,有助于对中国古代经济思想在新的视野和语境中进行更加深入的发掘和研究。     

回转窑煤粉喷射系统的燃烧技术

本文介绍了回转窑煤粉喷射系统的燃烧新技术及其机理。指出在燃煤中掺入适量的石灰石和添加剂共同燃烧,可以使回转窑的系统水泥产量提高5～10％,熟料中的游离氧化钙降低0.5～1.0％,煤耗降低 5％左右。     

Application of ICP-MS trace element analysis in study of ancient Chinese ceramics

Chemical analysis plays a significant role in the study of ancient ceramics[1,2]. Most ancient Chinese kilns used clays mined from the local areas and differences in the geochemistry and mineralogy of these raw materials may be expected. The chemical composition of ceramics may also be influenced by production techniques, such as processing by washing and mixing of different sorts of raw materials. These may also vary from kiln to kiln and even change over time. Thus the raw materials and pro…     

Neutron activation analysis and M(o)ssbauer spectroscopy research on coloring mechanism of ancient Chinese Guan porcelain

The content of 30 kinds of coloring elements in Guan porcelain in the Southern Song Dynasty has been determined by neutron activation analysis (NAA). Iron is the major coloring element. M(o)ssbauer spectroscopy has shown that the iron of the glaze exists in the form of structural iron (Fe2+, Fe3+). The quantitative relationship between the main wavelength of every color glaze and the relative content (Fe2+/Fe3+) of structural iron has been determined. Thus the coloring mechanism of Guan porcelain in the Southern Song Dynasty has been revealed entirely.     

《文选》钱氏学之陆机《文赋》研究——兼论《管锥编》之学术价值

陆机《文赋》研究在《文选》钱氏学中占重要位置,特别精彩处有四:一、揭文胆;二、辨“警策”与“警句”;三、释工拙相参;四、证灵感。对李善注肯定少否定多,且有嘲讽口吻。《管锥编》是一部博大精深的经典,是粉碎“四人帮”后文化界的第一声春雷,在中国学术史上的价值和影响难以估量;不可“臆说”。

大型多支承变刚度回转窑支承载荷分配问题

回转窑是冶金、水泥、耐火材料生产中的核心设备，是一种重载、大扭矩、多支点、静不定运行系统，由于其载荷和刚度分布复杂、各支承存在偏移，作用在它托轮上的支承载荷分配严重不均。本文针对回转窑载荷和刚度分布的特点，建立支承载荷求解的力学模型和线性方程组，导出支承载荷分配与支承偏差的关系式；用该方法对现场回转窑进行计算，得出该窑支承载荷分配的线性公式和一些分析结论，为生产中回转窑的状态分析、优化调控提供依据。
