近年来,随着江西工业化、城镇化的速度加快,江西的能源消费总量增长速度高于全国的平均水平,照此发展必将给江西的节能减排带来压力.本文对江西能源消费总量、能源消费品种的数据进行了分析,指出改善我省能源消费品种单一,结构不合理的途径之一便是大力发展低碳能源. 相似文献

一、世界和中国能源现状及中国面对的挑战
人类使用的能源有一个历史演变过程。19世纪上半叶以柴薪作为燃料，于20世纪中叶石油超过煤炭。目前，世界上的一次能源主要由石油、天然气、煤炭三种化石燃料所组成。据BP统计，2007年一次能源总量为11099．3百万吨油当量，化石燃料占世界一次能源的88％， 相似文献

The calculation of the radiation field D(x, y, z) produced by a uniform polygonal source is of considerable practical importance. Fock showed that there are advantages in replacing the traditional surface integral by a contour integral, using Stokes' theorem. This innovation, however, has not yet penetrated very deeply. It seemed worthwhile, therefore, to systematize the procedure and to show how easily results can be obtained by the Fock method. An incidental conclusion of the paper is that the radiation field from a polygonal source often differs by less than one per cent from the field produced by a circular disk of the same area. Thus the simple disk formula can often be substituted for the more complicated polygonal formula. 相似文献

The rectangular light source is more frequently encountered in engineering practice than any other form. Thus, both for artificial lighting and natural lighting, it is desirable to have convenient methods of obtaining the light distributions produced by rectangular sources. We have attempted to supply this need by calculating pharosage from sources of uniform helios and also for the non-uniform sources representing average overcast skies. Figures 5 to io are found to be particularly convenient in the visualization of light distributions.The results of these graphs are readily extended to any point and to surfaces tilted at any angle, provided that the plane of the illuminated surface does not cut the source.In conclusion, we wish to express our appreciation of the careful work of the computers: Messrs.

From the foregoing it appears that there are within the United States large stores of raw materials from which it is possible to obtain ample supplies of potash salts; that the technology of the subject is sufficiently developed to demonstrate the entire practicability of a supply from native sources, so far as physical factors are concerned. We can have “potash” if we really want it and are willing to pay for it. There are, however, serious commercial doubts affecting each of the four possible sources, and concerning the validity of these doubts opinions may well differ. Those most familiar with the problem are the most sanguine of the probability of commercial success.While it is undoubtedly true that governmental efforts can yet furnish assistance, there is a very serious doubt as to how far these efforts should be continued. The time seems to have arrived when the commercial interests should themselves squarely assume the tasks confronting them and the costs of what further experimenting is necessary. This they have been slow to do, but there is rapidly accumulating evidence that these interests are responding to the spur of necessity, and that sooner or later potash salts from American sources are to be upon the market. An early cessation of the European war might delay but can no longer stop the development of our potash resources. 相似文献
