Research needed relative to radiological Assessment of the dumping of radioactive wastes in the oceans 总被引:1,自引:0,他引:1
W. L. Templeton 《Marine pollution bulletin》1997,35(7-12):374-380
The purpose of this paper is twofold. First, the paper provides a historical review of international activities regarding radiation in the sea. Secondly, the paper provides some recommendations for future research needed for realistic dose assessment of the present and potential impact of ocean disposal and dumping operations. 相似文献

IntroductionSeismograms contain seismic wave data recorded by instruments. They are the main information source for seismological studies. Now we are developing seismological stations with digital records, which can offer seismic wave data with better quality than before. But the paper analog seismograms accumulated in the past decades still have great room for application. They are important original data for studying earthquakes. Lots of valuable information are contained in them. Due to a… 相似文献

This paper is the second one of a series of three papers on fluid evolution of the crust-upper mantle and the causes of earthquakes.
Based on the first paper, two conductive mechanisms of the crustal conductive layer (CCL), graphite and supercritical saline
aqueous fluids, are discussed. As there are difficulties for graphite model, the supercritical fluids are investigated in
this paper concerning the phases, the electrically conductive behaviors, the evolution and the sealing mechanisms of the fluids.
It is obvious that this model is reasonable to explain the geophysical and geochemical characteristics of the CCL presented
in the first paper. 相似文献

This paper is the follow-up of an earlier paper by the same author on the calculation of standard-graphs for horizontally stratified subsoils. The method which was developed in that earlier paper was destined for handwork; it was laid down in master-tables. The present paper deals with the presentation of similar methods to the computer expert in purely mathematical denotation. Two different denotations are described for the calculation of the image pole strengths involved. The first denotation is an improved version of Watsons formulae; it gives the total strengths. The second denotation preserves the character of successive approximations as described in the previous paper. Both denotations have been worked out until a six layer resistivity profile, but actually there is no limitation to the number of layers. There is no restriction to the resistivities of any layer. The only condition is now that all interface depths must be integers. This paper is followed by a paper on the relevant computer program by Argelo in this same issue 相似文献

对中国本世纪第五次大震高潮的探讨 总被引:2,自引:0,他引:2
本文首先指出从1988年11月澜沧7.6级地震开始,中国可能已进入了本世纪的第五次大震活动高潮,并将持续到2000年左右,之后将中国划分成十余个地震带,通过各带地震活动强度起伏的节律分析以及外部环境条件的辅助论证,确定出了滇、川、藏、青、北疆和东北深震区是本次大震的主体活动地区,并大致给出了它们发震的时间顺序。 相似文献
