Using the theoretical model of coda scattering from local earthquakes, we have studied the features of time-space variations of the attenuation rate β of coda amplitude and coda Qc-1 values before and after the Qina earthquakes (MS5.4 and MS5.1) in De

由上海技物所青年光电工程研究中心承担的国防科工委及中科院“八五”重点预研项目“光电混合实时图象处理技术研究”,经过课题组全体人员的努力已圆满完成,最近通过由中科院组织的专家鉴定。光电混合实时图象处理技术是当今国际信息技术研究领域里的前沿课题,上海技物所从实际应用出发,在国内外首先研制成用单光源多路(3×3,10×10)Vander Lugt光学相关结构的小型模式识别系统,并在实验室成功地进行了多种
对不同生理状态下细胞对外界刺激的反应情况进行了比较;研究了EDTA、氮酮、甲壳素做为长春花细胞渗透剂所使用的条件;探讨了它们影响胞内产物释放的短期效应、长期效应及长时间处理所造成的叠加效应。
随着电子技术、计算机技术以及数学、物理学等多学科的迅速发展,图像复制的理论、方法、工艺技术也在不断地变革和发展,现阶段图像复制已经从“模拟”复制发展到“数字”复制阶段。数字图像复制可以利用各种新技术对图
在爱尔兰都柏林,日立都柏林实验室的研究人员同来自都柏林市特里尼蒂学院物理系的专家合作,已研制成功一种人造眼睛。这种人造眼睛在某种程度上能够模仿人的视觉来识别形状和模式。这种“智能化网膜”的应用可以包括
Based on geometric structure,active strength,and maximum seismic rupture length along the fault in the late Quaternary or Holocene,this paper presents the segmentation of main active faults in Sichuan
The comparative study of the geologic and seismic dislocations often major active faults,such as the Aikin fault etc.,on China mainland,has shown that the ratio between the seismic slip rate(Vs)and ge
According to studies of more than 20 earthquakes with MS≥5.0 in North China, seven features of the short-term and imminent earthquake precursors have been summarized in this paper. At the same time, t
In this paper, the theory of the load/unload response ratio is applied to the prediction of the reservoir-induced earthquakes, and variation of the load/unload response ratio Y preceding the occurrenc
By analyzing seismograms of short period records at the Beijing SeismoJogicaJ Observatory, the present paper investigates the amplitude ratio of seismic phases. The results indicate that the amplitude
Through the collection of oriented samples,consolidation of undisturbed samples,and systematic microscopy of thin sections,the deformation products from the Daqingshan piedmont active fault zone have
