中国秽蝇族共有9个属,其中秽蝇属种类128种,溜头秽蝇属种类48种,分别是秽蝇族中较大的属。近年来中国各地报告秽蝇族种类很多,多在国外SCI刊物发表,国内学者在文献资料不全、标本较少和对种群个体变异认知不足的情况下,在发表的秽蝇族种类中很难避免出现同物异名或异物同名等问题。在完成国家自然科学基金项目的过程中,发现了《雷公山景观昆虫》专著中的秽蝇属和溜头秽蝇属的部分种类存在一些问题,其中秽蝇属8个种和溜头秽蝇属的12个种存在同物异名的次异名,共20种,根据外部和尾器形态特征相结合的方法分别作了订正。  相似文献

在有瓣蝇类中,多数种类只有雄性的描述,在秽蝇属分类工作中也是一块空白状态,这对于蝇类防治、利用和系统分类学研究都有重要影响。因此,根据斑股秽蝇Coenosia punctifemorata Cuiet Wang,1996的交尾标本进行了补充描述,完善了对雌性鉴定的科学性,提高了该种雌性描述的可靠性,可为上述领域的研究解决亟待解决的问题。文中列出了斑股秽蝇的种类鉴别特征,描述了雌性的外形特征,绘制了腹部和尾器的特征图,并补充了该种雄性的腹部特征图。该种的观察标本保存于沈阳师范大学昆虫研究所。  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
