In this paper the use of analogies in physics and in technology is analysed. First the important role philosophically deep rooted analogies played in romantic physics is discussed. The work of Schelling and Ritter is treated in particular. Second the mechanical analogue models in the kinetic theory of gases and in electrodynamics are examined, as well as the severe philosophical criticism which they received. A sketch of the theory of the electron gas is presented as an example for the success and the shortcomings of analogue models. Finally mechanical and electric analogue models in technology are considered; moreover biological analogies in engineering research, and the principle of similitude as applied to model experiments in shipbuilding are discussed. The analysis of the historical examples shows that in the 19th and 20th century the word “analogy” is no longer a vague notion. It represents a scientific method, which, however, inevitably leads to both an extension of the original theoretical models and to special theories of mapping. 相似文献

中美两国双边关系从贸易开始,又由贸易推进和发展。中美贸易是中美关系的主体,它在各个时期的演变对双边关系的发展有着巨大的影响,以往有关中美贸易关系的研究虽然受到重视,但具体的考察不够。本文拟将1912至1928年中美两国间的贸易关系作为研究对象,对此间中美贸易状况作一具体的考察,并对这一时期中美贸易的一些特点和影响两国贸易发展的诸因素,作一简要述评。 一、近代中美商贸关系的发展和民国成立后的激增 相似文献

编绳是简牍文物的重要组成部分,但由于其易于降解,在出土时多已腐朽甚至不存,故而通常不被重视,在文献中迄今亦未见到相关科学分析。北京大学收藏的西汉及秦代简牍中尚留存有编绳残段。为了从科学的角度了解其材质以及劣变状况,并为简牍研究及保护提供参考资料,本研究综合使用形貌、偏光、组织化学等显微分析手段,对这两批编绳样品进行了种属鉴定及成分分析。结果表明,两批编绳样品性质基本一致:其质料均为苎麻,其中纤维素,半纤维素及果胶质已无法检出,木质素和脂蜡质残留,但木质素中的醛基已发生改变。此外,秦简编绳中含有寄生虫卵,可能归属于华支睾吸虫,这符合于当时的流行病学资料以及葬制。 相似文献

Street peddlers were a common feature of city life in China well into the twentieth century. The presence of these small-scale, often single-good merchants can be traced back to earlier centuries. That they survived until after WWII reflects in part the state of economic development of China, where recent immigrants were prepared to take up the meanest, lowest-paid jobs to make a living. In Peking, thousands of peddlers roamed the streets, and more particularly, the hutongs where most of the population lived. They ceaselessly offered their goods and services to the residents, day and night. In order to attract customers and to entice them out of their walled houses and courtyards, peddlers uttered musical vocal phrases, sometimes in elaborate form, and more interestingly, they sometimes used musical instruments. In this paper I examine who they were, how they operated and what they represented to Peking's urban society. From this sketchy social portrait, I will move into a study of how the peddlers were represented in various settings of the pictorial records. Finally, I argue that peddlers were an integral part of a kind of street theater. This is not just a metaphor. Through their calls, songs, and music, peddlers created a constant flow of live entertainment in the street. 相似文献
