我国与南缘周边国家进行矿业合作的前景分析 总被引:1,自引:0,他引:1
我国南缘国家主要包括:印度、泰国、越南、老挝、印尼、马来西亚、菲律宾、柬埔寨、文莱、巴布亚新几内亚、孟加拉、巴基斯坦、缅甸、尼泊尔、不丹等国。其中大多数国家有着比较丰富的矿产资源。有些矿产资源与我国有着很强的互补性。例如:印度的铁和铬铁矿,泰国和老挝的钾盐,印尼和马来西亚的石油,印尼和菲律宾的铜,印度的锰,印度、越南、老挝的铝土矿。 相似文献

The author continues development of his concept of cartography as the “language of the map,” an earlier paper of this subject appearing in translation in M.S.R.S., 1985, No. 1. Although the term language has been widely used to describe cartographic communication, current theory fails to incorporate aspects of the language which provide for a comprehensive understanding of its structure and function. In particular, the language of the map and its symbolic elements cannot be explained reflexively by methods and rules of symbol and map design, since these elements were developed not before but after the existence of the language. The language of the map thus is proposed as the mechanism which provides for replicability or duplication in the way a system of mapmaking-map use functions (under diverse conditions, purposes, historical periods, and levels of training of users) through its different methods, models, and norms. Translated from: Geografiya i prirodnyye resursy, 1985, No. 3, pp. 142-151. 相似文献

油气藏中的挥发组份通过上覆地层微裂隙渗漏到地表,形成烃类物质地球化学异常晕。遥感作为一门新技术,已有效地应用到地表油气微渗漏异常的探测。本文主要介绍国外在因烃类微渗漏而造成的油气田地表土壤变化、岩石蚀变和地植物异常等方面的研究现状,以及国外在探索其形成机制方面的进展,并介绍国外石油遥感专家利用各种遥感手段进行烃类微渗漏探测的有效方法,望能达到推动我国石油遥感研究进一步深入与发展的目的。 相似文献

AbstractThe order of the constellations in the following catalogue is that of the list in Ptolemy's “Almagest, except that the modern groups in the northern hemisphere are inserted after Ptolemy's northern and before his zodiacal constellations, while the modern groups in the southern hemisphere follow the last of his list. The constellation-name in italic capitals is the Latin form in general use. It is followed by the English translation where necessary and by the French and German versions. The Greek and Arabic names, with their authorities, are then given and translated where they differ in meaning from the Latin. 相似文献

The theory of the solution of the stereogram is developed from the condition that the vector triangle, formed by the base-line and the two rays from the perspective centre to a common model point, shall be in equilibrium. Using this approach the unique definition of a point in the model follows naturally from the solution of the relative orientation problem. 相似文献

AbstractWe have seen that a few constellation-names used by us to-day make their appearance as far back as the Homeric poems, while the star-names Sirius and Arcturus are found in the works of Hesiod. We saw no reason to suppose that these early poets knew no names for other groups. They mentioned only those conspicuous heavenly objects that might occur in any general literature, as for example in the Old Testament books of Job and Amos. There are sporadic references to constellations in the extant works of the great Greek tragedians of the fifth century B.C., but these give us few additions to the Homeric list'. It is not till we come to the special literature of the subject that constellation-names appear in any quantity. The first specialist whose name stands out is the mathematician Eudoxus of Cnidus, a disciple of Plato, who lived in the first half of the fourth century B.C. He wrote a prose work entitled the “Phaenomena”, which, though unfortunately lost, was rendered into verse by the poet Aratus about 275 B.C. 相似文献

标尺误差是精密水准测量的一项重要误差来源。其中由于温度变化而引起因瓦带的长度变化,是使用因瓦标尺带来的误差之一。国内外有关文献曾对此进行过深入的研究。我国过去在精密水准测量时,未测定所用因瓦标尺的综合膨胀系数,故在一等水准网平差中未对观测高差加标尺温度改正。本文主要针对将要开始的精密水准复测,讨论标尺的温度改正问题和我们的试验结果。 相似文献

The attempts by A. S. Macdonald in the late 1980s and by J. A. Allan in the mid-1990s to integrate the UK societies and professional organisations within the spatial science field are described. The Photogrammetric Society, noting a long-term decline in its membership, set up an internal working group in 1997 to consider the future of the Society. A lengthy questionnaire to all individual members produced a 57% response and mandatory support for renewed action on greater inter-society cooperation.
A further effort to produce a wide amalgamation of bodies in the UK spatial science field on the Macdonald/Allan models failed for lack of support nationally. As a smaller step, perhaps to be extended later, a merger with the Remote Sensing Society was eventually agreed. The subsequent lengthy and delicate negotiations necessary to bring about a successful merger between these two mature, independently minded learned societies are described. The two societies were formally merged on 1st April 2001.
The author was a member of both the Photogrammetric and the Remote Sensing Societies and chaired the External Affairs Committee of the Photogrammetric Society preceding the merger. 相似文献
