项目摘要

1. Analysis of the fractal and electromagnetic properties of fault rocks : By using the apparatus of magnetic susceptibility and dielectric permittivity which were bought by Grant-in-Aid for Scientific Research (10740235), I studied the fractal and electromagnetic properties (i.e., magnetic susceptibilities and dielectric permittivities) 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 faults were discussed.2. Geological piezometer of fault rocks based on wearing of rocks or ceramics : Based on the wear theory of rocks or ceramics, a nonlinear wear model of natural fault rocks and a geological piezometer of fault rocks were proposed.3. Strength and strain of lithosphere and a real fault model : Based on the fractal and electromagnetic properties of fault rocks, the physical condition of fault formations. Using the piezometer and strain-meter of fault rocks proposed by this Grant-in-Aid for Scientific Research (10740235), the strength and strain of lithosphere were estimated and a real fault model was proposed. Moreover, based on the fractal, electromagnetic and wear properties of rocks or ceramics, this research cleared the state-of-stress problem and the electromagnetic structures (potentials) of a fault (shear) zone induced in the state-of-stress. Some of these results have been published and others are now submitted for the publication of international journals.

1.断层岩的分形和电磁特性分析：利用科研资助项目（10740235）购置的磁化率和介电常数测定仪，研究了断层岩的分形和电磁特性（即：磁磁化率和介电磁化率）。根据青年科学家和科学研究资助项目（07854024、08740389、10740235和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。并讨论了它们的性质与断层形变的关系.基于岩石或陶瓷磨损的断层岩地质测压仪：基于岩石或陶瓷磨损理论，提出了天然断层岩非线性磨损模型和断层岩地质测压仪.岩石圈强度、应变与一个真实的断层模型：基于断层岩石的分形和电磁特性，研究了断层形成的物理条件。利用国家科研资助项目（10740235）提出的断层岩石测压仪和应变仪，估算了岩石圈的强度和应变，提出了一个真实的断层模型。此外，基于岩石或陶瓷的分形、电磁和磨损特性，本研究澄清了应力状态问题和应力状态下诱导的断层（剪切）带的电磁结构（电位）。其中一些结果已经发表，另一些已提交国际期刊发表。
