进口具有预旋流动的亚音速轴对称环形扩压器粘性流场计算
,凌志光
工程热物理学报 , 1983,
Abstract: 环形扩压器是一个重要的气动元件.装在透平级后的轴向式或轴径式环形扩压器,通过它的排气扩压过程,可以降低透平级背压,在同样透平进口参数条件下,提高透平作功能力,减少余速损失,使整个透平机效率得到提高.
心灵计算理论与具身认知的哲学反思
新建,,
- , 2015,
Abstract: 具身认知的思想不是凭空提出的,它是在反对认知科学中主流的计算主义的基础上产生的,因此,在探讨具身认知之前,我们要对计算主义和相关的联结主义有足够的了解。具身认知反对表征和计算,对联结主义抱有同情,但是具身认知最近的发展也表现出一些和计算主义及联结主义关系不大的特征,而这些特征并非具身认知的本质特征。
Embodied cognition, which is not groundless, stands in opposition to computationalism, a prevailing theory of cognitive science. Hence, before discussing embodied cognition, we must have sufficient understanding of computaionalism and connectivism. Embodied cognition is opposed to representation and computation, but shows sympathy for connectivism. However, the recent developments in embodied cognition also display some features which have little to do with computationalism and connectivism. These features are not considered essential for embodied cognition
根据地温资料推断气候变化——当代理论地热研究的一个前沿课题

第四纪研究 , 1992,
Abstract: 近年来,在陆上进行热流测试或钻孔地温测量过程中,人们发现一些地区近地表数十米以至上百米的地温曲线发生某些“扭曲”或“畸变”现象,在排除了可能造成这些现象的各种因素诸如岩性变化、地形、植被以及地下水活动影响之后,地温曲线依然与稳态地温
GEOTHERMAL STUDIES IN CHINA -&mdash|PROMOTED BY PROFESSOR LI SIGUANG (J. S. LEE)
李四光教授倡导的中国地热研究


第四纪研究 , 1989,
Abstract: Professor Li Siguang is a distinguished geologist and geoscientist as well as a promoter of geothermal studies in China. He paid much attention and put much effort for promoting geothermal studies in our country during his life time. In the early 1970's, Professor Li suggested that the Earth must be regarded as a huge natural thermal reservoir and the mankind should "extract" heat from the Earth for their own use. As a consequence, a "heat"-wave of prospecting and exploration for geothermal energy was thus formed at that time all over the country. Since then, the scope and objects of geothermal studies in China have been extended. As a part of geothermal community in our country, Lab for Geothermics, Institute of Geology, Chinese Academy of Sciences engaged in both theoretical and application-oriented aspects of Geothermics, a number of high-quality results have been achieved. Approximately 200 reliable heat flow values have been obtained. The isotherm maps and the geothermal gradient maps of the North China Basin and the lower reaches of Liaohe River have been compiled. The Mohotemperature and the temperature in deep Earth crust, mantle heat flow and "reduced" heat flow have been calculated for Panxi Paleorift Belt, southwestern China and the North China Basin. In addition, the first "Heat flow Province" in China has been identified and the thickness of "thermal" lithosphere has been determined in Panxi Paleorift Belt. Based on paleogeothermal study, the history of thermal evolution since Meso-Cenozoic Era has been reconstructed in the North China Basin. In Qinghai-Xizang(Tibet) Plateau, the mechanism of high heat flow has been demonstrated and a conceptual model of multi-level thermal structure of the crust and upper mantle has been suggested. The mechanism of tectono-thermal evolution of Qinghai-Xizang Plateau has been exhibited as well. As to geothermal resources in the North China Basin, model of geo- thermal field forming has been suggested and assessment of thermal water resources have been made. The promising areas for geothermal development and the"perspectives" of utilization of geothermal resources in the North China Basin have been pointed out either. In Zhangzhou Geothermal Field, Fujian Prov., Southeast China,the circulating depth of thermal water, the reservoir temperature at depth,the temperature pattern and the heat flow of the Field as well as the origin model of Zhangzhou Geothermal Field have been studied systematically. In Yangbajing Geothermal Field, Xizang, well-testing, reservoir parameter analysing and regime monitoring have been conducted, good results were obtained. What about geothermal studies in mining areas, a classification of geothermal type of mines in China has been suggested. A methodology for predicting temperature at depth in mining areas and the geological engineering measure to prevent and reduce the so-called "geothermal hazard" in shafts and galleries have been formulated. It is very useful and helpful fo
一种利用地热资料判别地下水活动的新方法

科学通报 , 1991,
Abstract: 地下水活动对区域地温场和大地热流测试的影响,是当代地热研究中的一个前沿课题.众所周知,在地壳浅部,地下水活动普遍存在,但在地温测量或地热研究过程中,这种活动有时很难加以识别.本文在大量钻孔地温测量和资料分析的基础上,提出一种利用地热资料判别地下水活动的新方法.现报道如下:
攀西古裂谷大地热流测量

科学通报 , 1986,
Abstract: 大地热流在裂谷研究中占有重要位置。目前不少研究者认为,攀西地区是一个海西——印支期的古裂谷。其热状况如何?是否出现高热流就成为广大地学工作者所关心的大问题。 中国科学院地质研究所地热室和四川省地矿局攀西地质大队物探队合作,从1982年10月起在攀西地区进行了大量钻孔地温测量和岩石热导率测试,在此基础上计算大地热流值并
利用地热资料确定岩石圈厚度——以攀西地区为例

科学通报 , 1988,
Abstract: 利用地热资料确定岩石圈厚度是70年代后期发展起来的一种新方法。与其它地球物理方法相比,它具有耗资少、方法简便、结果系统等优点,因而近年来国际上发展很快。我们在完成“六·五”国家攻关项目攀西裂谷地质-地球物理研究的同时,利用地热资料确定了攀西地区的岩石圈厚度,同样取得了很好的效果。

科学通报 , 1990,
Abstract: 地下热水循环深度是热田研究中一个十分重要的参数,它在了解热水成因类型、热田形成机制以及进行地热资源潜力评价等方面起着很大的作用.本文根据作者近年来在漳州热田研究中所获得的大量实际资料,在管道模型计算法的基础上,对漳州地热田地下热水的循环深度做了计算,取得了令人满意的结果,现报道于下。
辽河盆地地热测量

科学通报 , 1985,
Abstract: 辽河盆地是一个在前中生代基底上发育起来的中、新生代断陷盆地,有人称之为“大陆裂谷”、“裂谷盆地”或“地堑”。地热方面曾报道过一个异常高的热流值(2.24HFU)并引起广大地学界的不同反响。近年来,我们于辽河油田开展系统地热研究的同时,进行了大地热流测量,所得结果与前不同,现报道于下
