我国古代化学的发展,是我国古代劳动人民开展自然斗爭的一个组成部分。两千多年来,历史上儒法两条路线斗爭,深刻地影响着我国社会生活的各个方面,也影响着我国科学技术的发展,包括古代化学的发展。当前,在馬克思主义、列宁主义、毛泽东思想指导下,闡明我国古代劳动人民在化学技术上所作的伟大貢献,正确評价法家在古代化学发展上所起的促进作用,批判儒家的阻碍、破坏作用,以促进我国化学事业沿着毛主席的无产  相似文献

本文对我国古代城市街道绿化和城市风景点的发展作了概括的阐述与考证。我国南北朝和唐宋都城的街道曾有完善的绿化设施;我国古代城市风景点的起源也很早,唐长安城的曲江是其中的一个典型,其他如苏州虎丘、杭州西湖、扬州瘦西湖等都是古代著名的城市风景游览区。本文对中国古代城市建设史提供了资料。  相似文献

在中国文学史上,小说与其它文学样式相比,尤其与诗歌相比,出现和成熟较晚。笔者认为,原因主要来自两方面:一方面,从我国古代小说的渊源看,它源于神话,而中国的古代神话并不发达;同时它又源于史传文学,但史传文学的真实性原则又阻滞了古代小说的发展,使小说创作由历史真实到艺术真实,经历了一个漫长的历史时期。另一方面,我国古代小说创作队伍的缓慢形成和封建统治阶级对小说创作的严重干预,也是我国古代小说发展繁荣滞后的重要原因。  相似文献

中山大学徐贤恭同志对我国古代化学的发展曾经作了论述,但其中对我国化学史上具有重要地位的酿酒化学并没有开展讨论。其实,在我国悠久的历史和灿烂的文化中,我国古代人民在酿酒发酵化学方面也曾经为世界人民作出过重要贡献。下面从三个主要方面加以论述。一、发明曲蘖酿酒——制曲酿酒术现在世界上酿酒技术可归为三大来源:一为古代埃及的麦芽啤酒生产;二为古代的欧洲葡萄酒酿造,三为我国古代发明的曲蘖酿酒以及发展至今的制曲酿酒技术。曲蘖酿酒技术的发明是我国古代人民重要贡献之一。从大量出土文物中,可以看到这一独创的工艺的光辉成就。离现在大约六千多年前的龙山文化时期,我们的祖先就使  相似文献

有鬲氏考     
我国古代,种族林立。在漫长的历史发展过程中,各种族通过联盟和战争等等,交流文化,相互融合,形成了华夏族(汉族的前身),而大多数种族在相互融合过程中逐渐消失了。为了进一步研究我国古代历史,找出各种族的发展、融合的线索,是十分必要的。本文就是探讨在我国古代种族融合过程中消失了的一个种族——有鬲氏。我国古代,各种族的命名多种多样。有的种族以图腾为名,如:熊、罴、貔、貅、  相似文献

Language markedness is a common phenomenon in languages, and is reflected from hearing, vision and sense, i.e. the variation in the three aspects such as phonology, morphology and semantics. This paper focuses on the interpretation of markedness in language use following the three perspectives, i.e. pragmatic interpretation, psychological interpretation and cognitive interpretation, with an aim to define the function of markedness.  相似文献

Language is a means of verbal communication. People use language to communicate with each other. In the society, no two speakers are exactly alike in the way of speaking. Some differences are due to age, gender, statue and personality. Above all, gender is one of the obvious reasons. The writer of this paper tries to describe the features of women's language from these perspectives: pronunciation, intonation, diction, subjects, grammar and discourse. From the discussion of the features of women's language, more attention should be paid to language use in social context. What's more, the linguistic phenomena in a speaking community can be understood more thoroughly.  相似文献

理论推导与室内实验相结合,建立了低渗透非均质砂岩油藏启动压力梯度确定方法。首先借助油藏流场与电场相似的原理,推导了非均质砂岩油藏启动压力梯度计算公式。其次基于稳定流实验方法,建立了非均质砂岩油藏启动压力梯度测试方法。结果表明:低渗透非均质砂岩油藏的启动压力梯度确定遵循两个等效原则。平面非均质油藏的启动压力梯度等于各级渗透率段的启动压力梯度关于长度的加权平均;纵向非均质油藏的启动压力梯度等于各渗透率层的启动压力梯度关于渗透率与渗流面积乘积的加权平均。研究成果可用于有效指导低渗透非均质砂岩油藏的合理井距确定,促进该类油藏的高效开发。  相似文献

As an American modern novelist who were famous in the literary world, Hemingway was not a person who always followed the trend but a sharp observer. At the same time, he was a tragedy maestro, he paid great attention on existence, fate and end-result. The dramatis personae's tragedy of his works was an extreme limit by all means tragedy on the meaning of fearless challenge that failed. The beauty of tragedy was not produced on the destruction of life, but now this kind of value was in the impact activity. They performed for the reader about the tragedy on challenging for the limit and the death.  相似文献

正The periodicity of the elements and the non-reactivity of the inner-shell electrons are two related principles of chemistry,rooted in the atomic shell structure.Within compounds,Group I elements,for example,invariably assume the+1 oxidation state,and their chemical properties differ completely from those of the p-block elements.These general rules govern our understanding of chemical structures and reactions.Using first principles calcula-  相似文献

We have developed an adiabatic connection to formulate the ground-state exchange-correlation energy in terms of pairing matrix linear fluctuations.This formulation of the exchange-correlation energy opens a new channel for density functional approximations based on the many-body perturbation theory.We illustrate the potential of such approaches with an approximation based on the particle-particle Random Phase Approximation(pp-RPA).This re-  相似文献

正The electronic and nuclear(structural/vibrational)response of 1D-3D nanoscale systems to electric fields gives rise to a host of optical,mechanical,spectral,etc.properties that are of high theoretical and applied interest.Due to the computational difficulty of treating such large systems it is convenient to model them as infinite and periodic(at least,in first approximation).The fundamental theoretical/computational problem in doing so is that  相似文献

For molecular systems,the quantum-mechanical treatment of their responses to static electromagnetic fields usually employs a scalar-potential treatment of the electric field and a vector-potential treatment of the magnetic field.Although the potential for each field separately is associated with the choice of an(unphysical)origin,the precise choice of the origin for the electrostatic field has little consequences for the results.This is different for the  相似文献

Franck-Condon factors bridge the gap between theoretical modeling and experimental observations for molecular electronic spectroscopy and electron transfer.Under the displaced harmonic oscillator approximation,multidimensional Franck-Condon factors are decomposed into a product of many one-dimensional(1D)Franck-Condon(FC)factors,and each 1D-FC factor is associated with one Huang-Rhys factor that determines the leading contribution of  相似文献
