1.地震断层的分形、电磁和辐射特性分析利用科研资助项目(10740235)购买的介电常数测定仪和该资助项目购买的NaI闪烁测量仪、伽马辐射光谱仪,研究了断层岩或断裂带的分形、电磁和辐射特性(介电常数、IR、CL、TL、摩擦放电等离子体、放射性核素通道和大气电变化)。根据国家青年科学研究资助项目(07854024、08740389、10740235、12640436)的研究成果,提出了断层各参数与断层岩石或断裂带的分形、电磁和辐射特性之间的关系。此外,还讨论了地震断层(双叶断裂、朝日单斜弯曲和苏断裂)的性质与变形之间的关系。…更多地震断层的地质测压仪和应变仪:根据实验室实验数据与自然界实测数据的关系,提出了地震断层的分形与电磁特性的一些关系。此外,还研究了地壳岩石的非线性瞬态力学行为和时温叠加原理。岩石圈强度应变和真实地震断层模型:基于断层岩石和断裂带的分形、电磁和辐射特性,研究了地震断层的各种物理条件。本科研资助项目(C)的研究澄清了应力状态问题,提出了一个真实的地震断层模型。此外,基于断裂岩石和断裂带的分形、电磁和辐射特性,研究了地震断裂带内或应力状态下大地震诱发前的电磁结构(电位)及其来源。其中一些结果已发表,另一些结果已提交国际期刊发表。少
英文摘要
1.Analysis of the fractal, electromagnetic and radiation properties of earthquake faults : By using the apparatus of dielectric permittivity bought by Grant-in-Aid for Scientific Research (10740235) and NaI scintillation survey meters and gamma-radiation spectrometer bought by this Grant-in-Aid, I studied the fractal, electromagnetic and radiation properties (i.e., dielectric permittivities, IR, CL, TL, frictional discharge plasma, radionuclide channels and atmospheric electricity variation) of fault rocks or fault zones. From the results from the Grant-in-Aids for Encouragement of Young Scientist and Scientific Research (07854024, 08740389, 10740235 and 12640436), this study proposed some relationships among each parameter on faults and the fractal, electromagnetic and radiation properties of fault rocks or fault zones. Moreover, some relations between their properties and deformation of earthquake faults (e.g., Futaba fault, Asahiyama monoclinal flexure and Sue fault) were discussed. … More 2.Geological piezometer and strain-meter of earthquake faults : Based on the relation between the experimental data in my laboratory and measured data in nature, some relationships between the fractal and electromagnetic properties of earthquake faults were proposed. Moreover, a nonlinear transient mechanical behavior and time-temperature superposition principle of crustal rocks were investigated.3.Strength and strain of lithosphere and a real earthquake fault model : Based on the fractal, electromagnetic and radiation properties of fault rocks and fault zones, the various physical conditions of earthquake faults were investigated. The research by this Grant-in-Aid for Scientific Research (C) cleared the state-of-stress problem in order to propose a real model for earthquake faults. Moreover, based on the fractal, electromagnetic and radiation properties of fault rocks and fault zones, the electromagnetic structures (potentials) and their sources in earthquake faults or before big earthquakes induced in the state-of-stress were investigated. Some of these results have been published and others are now submitted for the publication of international journals. Less
