项目摘要

1.Analysis of the fractal and electromagnetic properties of shear zones : By using the apparatus of dielectric permittivity which were bought by Grant-in-Aid for Scientific Research (10740235), I studied the fractal and electromagnetic properties (i.e., dielectric permittivities, IR,CL and TL) of fault rocks. 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 and electromagnetic properties of fault rocks. Moreover, some relations between their properties and deformation of shear zones were discussed.2.Geological piezometer and strain-meter of shear zone : Based on the relation between the differential geometry and physical field (physical interaction filed), the relationships between the fractal and electromagnetic properties of shear zones were proposed. Moreover, a nonlinear wear model of natural fault rocks and a geological piezometer of fault rocks were proposed, and a nonlinear transient mechanical behavior and time-temperature superposition principle of crustal rocks were investigated.3.Strength and strain of lithosphere and a real shear zone model : Based on the fractal and electromagnetic properties of fault rocks, the various physical conditions of shear (fault) zones were investigated. Using the piezometer and strain-meter of fault rocks, the strength and strain of lithosphere were estimated, and this research cleared the state-of-stress problem in order to propose a real model for shear (fault) zones. Moreover, based on the fractal and electromagnetic properties of fault rocks, the electromagnetic structures (potentials) and their sources in shear (fault) zones 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.

1.剪切带的分形和电磁特性分析：利用科研资助项目（10740235）购置的介电常数测量仪，研究了剪切带的分形和电磁特性（即，介电常数（IR、CL和TL）。根据国家青年科技奖励基金（07854024、08740389、10740235、12640436）的研究结果，提出了断层各参数与断层岩分形和电磁特性之间的关系。2.剪切带的地质测压仪和应变仪：基于微分几何与物理场（物理相互作用场）之间的关系，提出了剪切带的分形与电磁特性之间的关系。3.岩石圈强度、应变和真实的剪切带模型：基于断层岩的分形和电磁特性，研究了剪切（断层）带的各种物理条件。利用断层岩石测压仪和应变仪，估算岩石圈的强度和应变，解决应力状态问题，提出一个真实的剪切（断层）带模型。此外，根据断层岩的分形和电磁特性，研究了应力状态下剪切（断层）带中电磁结构（势）及其来源。其中一些结果已经发表，另一些已提交国际期刊发表。
