摘要
综述了地壳深部流体研究的进展并提出了在地震领域应该深入研究的方面。已有大量资料表明岩石圈是一含流体的系统，也是地震发育的主要场所。深部流体赋存相态、运移方式及其与岩石的反应，对震源介质和构造活动有重要影响。深部流体不仅影响岩石力学性质和化学组成，而且影响地电、地磁等地球物理性质。因此加强深部流体的研究，有助于全面认识地震孕育及其征兆的形成。
The role of deep crust fluids during earthquake activity is reviewed,and some aspects to be urgently studied are proposed. A lot of data indicate that lithosphere is a fluid bearing system in which most of earthquake occurred.The phase change, migration of fluids and fluid rock interaction have the important effects on focal medium and tectonic activity. The following subjects would be further studied: ①the heterogeneity of fluids in lithosphere, ②the existing forms and geochemical mechanism of fluids,③migration mechanism of fluid,④the experiment and digital modelling on interference among fluid,stress and geothermal field,⑤the role of fluid in double force couple and other earthqake generation,⑥the relationship between fluid activity and telluric electromagnetic varieties,⑦mechanism of earthquake wave emission of facies exchange in the deep crust,⑧fluid rock interaction effects on dynamic features of the focal medium,⑨multiple monitoring of seismic measurement,fluid, gravity, tilt, geothermics and telluric electromagnetism.
