一个新颖的哲学理论：突现论及其在地质上的应用          下载免费PDF全文

张旗 《甘肃地质》2022,(1):1-11

突现论是一个崭新的哲学理论,只有100多年的历史,但是,突现论已经崛起为复杂性系统的核心理论,成为近期哲学领域研究的热点之一。突现论认为,世界是由不同层级（或层次）构成的,不同层次按照事物的复杂程度不断提高划分的。世界基本上有三大层次,从低到高为物理、生命和心灵。突现论有4个特征：1,不同层次性质不同,高层次性质来源于低层次;2,突现具有不可预测的新颖性;3,不可还原性;4,高低层次之间存在因果关系。文中简要介绍了突现论的概念并探讨了突现论在变质岩、岩浆岩、矿床学以及地球演化研究中的可能的应用,希望能够对科学研究的进一步发展有利。  相似文献   

Sunspot numbers based on historic records in the 1610s: Early telescopic observations by Simon Marius and others     

R. Neuhuser  D. L. Neuhuser 《Astronomische Nachrichten》2016,337(6):581-620

Hoyt & Schatten (1998) claim that Simon Marius would have observed the sun from 1617 Jun 7 to 1618 Dec 31 (Gregorian calendar) all days, except three short gaps in 1618, but would never have detected a sunspot – based on a quotation from Marius in Wolf (1857), but mis‐interpreted by Hoyt & Schatten. Marius himself specified in early 1619 that for one and a half year... rather few or more often no spots could be detected... which was never observed before (Marius 1619). The generic statement by Marius can be interpreted such that the active day fraction was below 0.5 (but not zero) from fall 1617 to spring 1619 and that it was 1 before fall 1617 (since August 1611). Hoyt & Schatten cite Zinner (1952), who referred to Zinner (1942), where observing dates by Marius since 1611 are given but which were not used by Hoyt & Schatten. We present all relevant texts from Marius where he clearly stated that he observed many spots in different form on and since 1611 Aug 3 (Julian) = Aug 13 (Greg.) (on the first day together with Ahasverus Schmidnerus); 14 spots on 1612 May 30 (Julian) = Jun 9 (Greg.), which is consistent with drawings by Galilei and Jungius for that day, the latter is shown here for the first time; at least one spot on 1611 Oct 3 and/or 11 (Julian), i.e. Oct 13 and/or 21 (Greg.), when he changed his sunspot observing technique; he also mentioned that he has drawn sunspots for 1611 Nov 17 (Julian) = Nov 27 (Greg.); in addition to those clearly datable detections, there is evidence in the texts for regular observations. For all the information that can be compared to other observers, the data from Marius could be confirmed, so that his texts are highly credible. We also correct several shortcomings or apparent errors in the database by Hoyt & Schatten (1998) regarding 1612 (Harriot), 1615 (Saxonius, Tard´e), 1616 (Tard´e), 1617–1619 (Marius, Riccioli/Argoli), and Malapert (for 1618, 1620, and 1621). Furthermore, Schmidnerus, Cysat, David & Johann Fabricius, Tanner, Perovius, Argoli, and Wely are not mentioned as observers for 1611, 1612, 1618, 1620, and 1621 in Hoyt & Schatten. Marius and Schmidnerus are among the earliest datable telescopic sunspot observers (1611 Aug 3, Julian), namely after Harriot, the two Fabricius (father and son), Scheiner, and Cysat. Sunspots records by Malapert from 1618 to 1621 show that the last low‐latitude spot was seen in Dec 1620, while the first high‐latitude spots were noticed in June and Oct 1620, so that the Schwabe cycle turnover (minimum) took place around that time, which is also consistent with the sunspot trend mentioned by Marius and with naked‐eye spots and likely true aurorae. We consider discrepancies in the Hoyt & Schatten (1998) systematics, we compile the active day fractions for the 1610s, and we critically discuss very recent publications on Marius which include the following Maunder Minimum. Our work should be seen as a call to go back to the historical sources. (© 2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)  相似文献

李旭旦先生的学术翻译及其反映的学术理念     

汤茂林 《地理研究》2013,32(7):1364-1374

李旭旦先生在一生中译著无数,其中为学界所重者莫过于《人地学原理》、《海陆的起源》、《地理学思想史》、《国外地理科学文献选译》。改革开放以来,李先生花了大量宝贵的时间从事学术翻译,其实大有深意。他将翻译作为其复兴全面的人文地理学大业的一部分,是走向世界的基础性工作,也是高水平研究的基础之一,他对学术翻译的重视还隐含了其对学术讨论和对话的重视。目前,我们对世界人文地理学发展仍比较隔膜,为了避免20 世纪50 年代学习苏联时犯下的错误,必须大力迻译国际上的重要研究成果,全面了解国际上的学术状况,形成我们自己的判断,然后确定我们的研究论题和研究方法,从事原创性的研究,编写出世界水准的教科书和著作,走向世界。需要提升学术翻译在学术评价中的地位,这也是李先生翻译工作给我们的启示之一。  相似文献

The Chinese comet observation in AD 773 January     

J. Chapman  M. Csikszentmihalyi  R. Neuhuser 《Astronomische Nachrichten》2014,335(9):964-967

The strong ¹⁴C increase in the year AD 774/5 detected in one German and two Japanese trees was recently suggested to have been caused by an impact of a comet onto Earth and a deposition of large amounts of ¹⁴C into the atmosphere (Liu et al. 2014). The authors supported their claim using a report of a historic Chinese observation of a comet ostensibly colliding with Earth's atmosphere in AD 773 January. We show here that the Chinese text presented by those authors is not an original historic text, but that it is comprised of several different sources. Moreover, the translation presented in Liu et al. is misleading and inaccurate. We give the exact Chinese wordings and our English translations. According to the original sources, the Chinese observed a comet in mid January 773, but they report neither a collision nor a large coma, just a long tail. Also, there is no report in any of the source texts about “dust rain in the daytime” as claimed by Liu et al. (2014), but simply a normal dust storm. Ho (1962) reports sightings of this comet in China on AD 773 Jan 15 and/or 17 and in Japan on AD 773 Jan 20 (Ho 1962). At the relevant historic time, the Chinese held that comets were produced within the Earth's atmosphere, so that it would have been impossible for them to report a “collision” of a comet with Earth's atmosphere. The translation and conclusions made by Liu et al. (2014) are not supported by the historical record. Therefore, postulating a sudden increase in ¹⁴C in corals off the Chinese coast precisely in mid January 773 (Liu et al. 2014) is not justified given just the ²³⁰Th dating for AD 783 ± 14.

Digitization of sunspot drawings by Spörer made in 1861–1894     

A. Diercke  R. Arlt  C. Denker 《Astronomische Nachrichten》2015,336(1):53-62

Most of our knowledge about the Sun's activity cycle arises from sunspot observations over the last centuries since telescopes have been used for astronomy. The German astronomer Gustav Spörer observed almost daily the Sun from 1861 until the beginning of 1894 and assembled a 33‐year collection of sunspot data covering a total of 445 solar rotation periods. These sunspot drawings were carefully placed on an equidistant grid of heliographic longitude and latitude for each rotation period, which were then copied to copper plates for a lithographic reproduction of the drawings in astronomical journals. In this article, we describe in detail the process of capturing these data as digital images, correcting for various effects of the aging print materials, and preparing the data for contemporary scientific analysis based on advanced image processing techniques. With the processed data we create a butterfly diagram aggregating sunspot areas, and we present methods to measure the size of sunspots (umbra and penumbra) and to determine tilt angles of active regions. A probability density function of the sunspot area is computed, which conforms to contemporary data after rescaling. (© 2015 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim)  相似文献
