| 摘 要： | 岩石层的流变学是一门综合性的学科，它不仅包括高温高压岩力学实验，而且还包括岩石圈的地质构造，物质组成和温度场特性的研究，70年代以来岩石力学实验和地质热研究的成果推动了岩石层流变学的发展，目前，人们应用已有的实验结果建立了岩石层流变学的剖面，并以此为基础讨论了许多大地构造现象，但是，人们对流变机制的转换，水对岩石层流变性的影响等问题尚不清楚，因此，为了深入的了解岩石层流变性质在岩石层运动学和动力学中的应用，必须开展岩石层流变机制的理论和实验研究，以便建立流变性质的三维分布，本文主要分析了岩石层的流变性质随深度变化的研究结果及其在实际中的应用，讨论了确定岩石层粘度或流变强度的主要因素并对岩石层的流变学研究方向提供了一些看法。

| Abstract: | Rheology of lithosphere, a comprehensive subject, not only includes experiment of rocks at high temperature and high pressure, but also includes the research about geological structure, material composition and geotherm of lithosphere. Since the 1970's, the rheology has been promoted by the fruits of experiment of rocks and study of geotherm. Now, profile of rheology has been established by using present experimental results, by which many geotectonic phenomena have been interpreted. However, people could not manifestly explain many problems about the rheology, such as the transition of rheological mechanism, effects of water on rheological characters, and so on. Therefore, in order to catch on the application of rheology in kinematics and dynamics of lithosphere, we must develop the research about theory and experiment of rheology, so the three dimensional rheological structure can be established. |
