Liu, Q., Khramov, A.V. & Zhang, H.C., 21.4.2015. A new species of Kalligramma Walther, 1904 Walther, J., 1904. Die Fauna der Solnhofener Plattenkalke bionomisch betrachtet. Denkschriften der Medizinisch-Naturwissenschaftlichen Gesellschaft zu Jena 11, 133214. [Google Scholar] (Insecta, Neuroptera, Kalligrammatidae) from the Middle–Upper Jurassic of Daohugou, Inner Mongolia, China.

A new species of Kalligramma Walther, 1904 Walther, J., 1904. Die Fauna der Solnhofener Plattenkalke bionomisch betrachtet. Denkschriften der Medizinisch-Naturwissenschaftlichen Gesellschaft zu Jena 11, 133214. [Google Scholar] (Insecta, Neuroptera, Kalligrammatidae) is described as Kalligramma delicatum based on a nearly complete forewing from the Middle–Upper Jurassic of Daohugou, Inner Mongolia, China. The new species is characterized by the narrow costal space with sinuous costal veinlets, Rs with eight primary branches, MP with five pectinate branches and 1A forked beyond its mid-length. The forewing of Kalligramma can be distinguished from the hind wing by its ovate rather than subtriangular shape, significantly wider costal space and more numerous crossveins between costal veinlets. The new species is interpreted to represent a forewing based mainly on its shape.

<正>The concept of"purity"and"pollution"exists in every ethnic group or culture,and the emergence and existence of this concept is closely associated with geographic environment,religious belief,mode of production,lifestyle,morals and world outlook,and is supported and restricted by a whole set of cultural logics hidden deeply in the social structure.Different ethnic groups and cultures have different criteria for classification of"purity"and"pollution".One article,behavior or social phenomenon may be deemed"pure"by one ethnic group,but"polluted"by another.The human perception of"purity"is a  相似文献

This paper explores the concept of heritage as part of sustainable development planning. Heritage is taken to include both the cultural and natural spheres to incorporate people, activities, landscapes, monuments, landmarks, artefacts, and nature. Heritage planning then involves the sustainable development of the cultural and natural environment to prepare for its stewardship, research, and communication for the benefit of society. This perspective leads to broader questions on approaches to heritage planning where the cultural environment is considered specifically within sustainable development planning just as the natural environment is studied separately in specialised disciplines. The paper proposes that in developing resource‐management plans the effects of cultural resources on natural resources, and vice versa, must be integrated and addressed. Seoul, Korea, an historic metropolitan city that has gone through radical political and economic changes, is examined as a case study. It identifies how the city is integrating sustainability of the contextual association of the cultural and natural environment with promotion of economic growth.  相似文献

Beam-column connections are zones of highly complex actions and deformations interaction that often lead to failure under the effect of earthquake ground motion. Modeling of the beam-column connections is important both in understanding the behavior and in design. In this article, a framework for developing a neural network (NN) based steel beam-column connection model through structural testing is proposed. Neural network based inelastic hysteretic model for beam-column connections is combined with a new component based model under self-learning simulation framework. Self-learning simulation has the unique advantage in that it can use structural response to extract material models. Self-learning simulation is based on auto-progressive algorithm that employs the principles of equilibrium and compatibility, and the self-organizing nature of artificial neural network material models. The component based model is an assemblage of rigid body elements and spring elements which represent smeared constitutive behaviors of components; either nonlinear elastic or nonlinear inelastic behavior of components. The component based model is verified by a 3-D finite element analysis. The proposed methodology is illustrated through a self-learning simulation for a welded steel beam-column connection. In addition to presenting the first application of self-learning simulation to steel beam-column connections, a framework is outlined for applying the proposed methodology to other types of connections.  相似文献

The completeness of the complex response spectrum method for both formally underdamped and overdamped modes is theoretically proved, and the physical meanings of the decoupled modes as well as involved parameters are recognized and clarified in this paper. For the system with relatively large non-classical damping, the eigenvalue pairs generated by the complex mode decomposition method are real and the so-called modal damping ratios are larger than unity. In this paper, we firstly clarified that the decoupled modes are virtual and the so-called modal frequency and damping ratio are mathematical parameters that have no physical meaning. Then, the completeness of the complex response spectrum method for both formally underdamped and overdamped modes is rigorously proved by allowing the “damping frequency” to be an imaginary number. For the virtually overdamped modes, Duhamel integral involved in the calculation for formally underdamped modes automatically convert to hyperbolic Duhamel integral. A numerical example taken from the published literature is given to verify this method. Structural responses for the system with coupled damping under multi-support seismic excitations are further analyzed and numerical results indicate the accuracy of complex response spectrum method.  相似文献

大清定鼎中原前夕和之后一个半世纪,在满汉文化思想接触、碰撞、相互融合的历史过程中,清帝出自居安思危、巩固皇权和延缓政权衰落周期的目的,在皇族宗室子孙、八旗子弟及中枢臣僚中开展民族传统教育,强调“力戒汉俗”、“不忘满洲骑射旧俗”,并将其视为“祖宗家法”和与国家民族命运攸关的基本教育之法。自太宗至仁宗嬗递六代,其间因各朝政治形势和教育针对性的变化,发生诸多修正,由此反映出社会进步的历程。  相似文献

后55年体制下的日本市民运动   总被引:1,自引:0,他引:1  
本文拟从“后55年体制”下的日本市民运动这一角度出发对当代日本社会的发展演进做一分析,笔者认为,从中长期的发展看,20世纪90年代后期出现的“后55年体制”是一种过渡性体制,日本政治在未来相当一段时期仍将处于一个寻求变革的调整期,在这一调整期,方兴未艾的日本市民运动正在成为对当代日本政治产生巨大影响的重要因素,基于这一认识,笔者还就当代日本市民运动的发展基础与“后55年体制”下的日本市民运动的积极因素做了初步的分析和讨论。  相似文献

根据窑址标本和传世品而知,"皇帝万岁"铭瓷器至迟在北宋时已出现,延续至明清.佛教将皇帝比作佛,并以世俗方式颂之,原出于自我保护和发展的需要,也是它接受和利用中国文化价值观念的表现."皇帝万岁"铭瓷器可说是中国佛教走向本土化、世俗化的一个见证.  相似文献

《俘虏记》是日本战后文学中具有广泛影响的反映日本侵略战争的作品之一。小说中,作家以主人公“我”没有向美国士兵开枪为主要情节,说明作为侵略士兵的“我”是“善良的”和“有人性的”。这显然是在为日本士兵的侵略罪行辩解。通读作品,我们会发现,主人公“我”之所以没有开枪,是因为想不被追击的美军发现,保全自己的生命。显然,作家在这里偷换了概念,其用心是为了掩盖日本侵略军的野蛮行径。因此,对这篇小说的错误战争认知理念。我们应当以批判的态度来分析。  相似文献
