最早在吉安传播马克思主义的不是罗石冰,刘九峰,曾延生,而是袁玉冰,赵醒侬,方志敏,曾天宇,邹努等。吉安第一批共产党员不是宋大勋,郭化非,刘承休,谌光重,而是袁玉冰,罗石冰,曾延生,邹努,来吉安建党的不只是罗石冰一人,还有欧阳洛,艾焕彩,刘家麒,龙超清,李锦云,陈正人,贺铁汉,吉安建党时间不是1923年8月,也不是1925年7-8月,而是1926年1月26日,吉安最早的党组织不是中共吉安支部,而是中共吉安小组。  相似文献

在高等代数的教学中,学生们的反映是"概念多,论证多,方法多样,内容比较抽象。"因此,有的学生说:"高等代数听懂容易,记住难,使用更难。"我们认真究其根源,关键是对概念的理解不深不透,对定理的论证似懂非懂,定理本质木曾掌握,因而,有时解题论证入手困难,所以,在高等代数的教学过程中,必须设法引导学生学会应用概念,使用定理,进行解题论证,近几年来,我们在教学过程中,结合具体内容,自觉地多举实例,用分析,对比的方法,处理好具体和抽象,特殊与一般这两对矛盾,从而使学生能仔细体会,认真理解,确切掌握概念的内涵及…  相似文献

在美术界,我喜欢结识那些默默无闻地探索,不计名利,真正有水平的人,接近他们,了解他们……我要介绍给大家的童和平,他没有显赫的头衔和名望,人很平常,但当我见到他的作品时,我很惊喜。他的画很现代,又很传统,重一“写”字,抒情写意,笔墨浓厚,气韵生动,大气磅礴,雄强壮阔,造景具象又抽象,意境宏观,表现着强烈的生活感受,充满着积极向上的生机和活力,极具象征意义和隐喻性,内涵丰富,耐人寻味。自由而自然的创作心境,使其作品极富变化,既没有定型的套路,也没有规范、成法与概念的束缚,乱中有序,动中有静,柔中有刚…  相似文献

五代,两宋是中国绘画史上的重要时期,其山水画在空间布局上的巧妙处理,对后世山水画的发展产生了重要的影响,五代,北宋的山水画,侧重于完整地,整体地把握客观对象,以繁复的,“全景式”的构图,显示一种雄浑,博大的气象,南宋山水画,则以少取胜,强调对景物的大胆剪裁,以简约的,“边角式”的布局,营造出一种空灵的,诗一般的氛围。  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

Wuthering Heights, Emily Bronte's only novel, was published in December of 1847 under the pseudonym Ellis Bell. The book did not gain immediate success, but it is now thought one of the finest novels in the English language. Catherine is the key character of this masterpiece, because everybody and everything center on her though she had a short life. We can understand this masterpiece better if we know Catherine well.  相似文献

The Williston Basin is a significant petroleum province, containing oil production zones that include the Middle Cambrian to Lower Ordovician, Upper Ordovician, Middle Devonian, Upper Devonian and Mississippian and within the Jurassic and Cretaceous. The oils of the Williston Basin exhibit a wide range of geochemical characteristics defined as "oil families", although the geochemical signature of the Cambrian Deadwood Formation and Lower Ordovician Winnipeg reservoired oils does not match any "oil family". Despite their close stratigraphic proximity, it is evident that the oils of the Lower Palaeozoic within the Williston Basin are distinct. This suggests the presence of a new "oil family" within the Williston Basin. Diagnostic geochemical signatures occur in the gasoline range chromatograms, within saturate fraction gas chromatograms and biomarker fingerprints. However, some of the established criteria and cross-plots that are currently used to segregate oils into distinct genetic families within the basin do not always meet with success, particularly when applied to the Lower Palaeozoic oils of the Deadwood and Winnipeg Formation.  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
