根据创造性的层次,似乎可将基础研究划分为开创性、变革性、跟进性、跟踪性和模仿性研究五类。开创性研究开辟新学科、新方向、新领域,形成新理论、新体系、新框架;变革性研究改变或更正原有理论和范式,形成新理论和新范式;跟进性研究虽然没能开创或变革,但能后来居上,领导潮流;跟踪性研究主要是跟在人家后面,做些补充和拾遗工作,当然有时也可产生一些亮点工作; 相似文献

2007年12月12日,第二届林学名词审定委员会第三次工作会议由尹伟伦院士主持。根据全国科技名词委对学科问词条的查重结果,逐条展开了讨论,确定了重复词条的学科归属。专家们一致建议在原来的12个学科分支基础上,增加“总论”部分,以收录“林业基础”中不能包含的一些共有名词和基本学科名称类名词。 相似文献

该文依据历史文献上记载的宋代和金代的几部已经佚失的历法的若干残缺数据,对其中王睿、至道、乾兴与乙米四历的历元及其历取回归年与朔望月常数进行了考证和可靠的校算,得到了王睿、至道二历的相应历取值,验证了鲁实先、严敦杰先生关于乾兴历的推算,校证了李锐关于乙未元历回归年长度的失误等。 相似文献

《自然辩证法通讯》自1979年创刊以来,由于海内外读者的热情关怀和激励,广大作者的支持和帮助,以及各个时期编者的潜心和努力,在30年间逐渐形成自己颇有特色的定位、旨趣、追求和格调。这一切在1990年代中期、尤其是在21世纪伊始,已经明晰地彰显出来,并且得以明确表达——在编辑部短评中, 相似文献

现代科学信念真、善、美的三元结构 总被引:1,自引:0,他引:1
现代科学信念是科学家和科学共同体科学认识活动中必不可少的预设和基本前提,是一个由真、善、美构成的三元结构系统。真、善、美之间相互渗透、相互依存并达到完整统一。现代科学信念对科学认知有着重要的激励约束作用,是当代科学活动宏观调控的深层思想基础和哲理依据。 相似文献

The aim of the paper is to introduce some of the history and key concepts of network science to a philosophical audience, and to highlight a crucial—and often problematic—presumption that underlies the network approach to complex systems. Network scientists often talk of “the structure” of a given complex system or phenomenon, which encourages the view that there is a unique and privileged structure inherent to the system, and that the aim of a network model is to delineate this structure. I argue that this sort of naïve realism about structure is not a coherent or plausible position, especially given the multiplicity of types of entities and relations that can feature as nodes and links in complex networks. 相似文献

This paper was written with two aims in mind. A large part of it is just an exposition of Tarski's theory of truth. Philosophers do not agree on how Tarski's theory is related to their investigations. Some of them doubt whether that theory has any relevance to philosophical issues and in particular whether it can be applied in dealing with the problems of philosophy (theory) of science.In this paper I argue that Tarski's chief concern was the following question. Suppose a language L belongs to the class of languages for which, in full accordance with some formal conditions set in advance, we are able to define the class of all the semantic interpretations the language may acquire. Every interpretation of L can be viewed as a certain structure to which the expressions of the language may refer. Suppose that a specific interpretation of the language L was singled out as the intended one. Suppose, moreover, that the intended interpretation can be characterized in a metalanguage L
+. If the above assumptions are satisfied, can the notion of truth for L be defined in the metalanguage L
+ and, if it can, how can this be done? 相似文献

The painter' s studio should be a laboratory. There one does not make art in the manner of a monkey, one invents. Painting is a play of the mind. 相似文献
