9351386 Hudleston A new Geodynamics Laboratory is being created within the Department of Geology and Geophysics. This laboratory is for experimentation on processes of fundamental importance in various areas of the Earth Sciences, representing a variety of fields but all falling under the general rubric of continuum mechanics. Experimental topics include flow of water in open channels, porous media, lakes, and rotating basins; flow of complex geological materials such as debris; deformation of plastic materials in two and three dimensions; and plate motion on a fluid undergoing three-dimensional convection. The experiments are being coupled with computer models of the processes studied.The laboratory is a unique complement to the more traditional sample-oriented laboratories in our and other Earth Sciences Departments. It is giving students a unique opportunity to visualize and manipulate models of processes that they previously studied about mainly through lectures. Also, by grouping these experiments in one place, using generic, simple materials, and incorporating them in fundamental courses taught at the beginning of the undergraduate curriculum, the new laboratory is helping students appreciate the unity of the physics underlying many apparently diverse geologic processes. ***

9351386 Hudleston地质与地球物理系正在建立一个新的地球动力学实验室。本实验室用于对地球科学各个领域中具有重要基础意义的过程进行实验，这些过程代表了不同的领域，但都属于连续介质力学的一般范畴。实验课题包括水流在明渠，多孔介质，湖泊和旋转盆地；碎屑等复杂地质物质的流动；塑性材料的二维和三维变形；以及板块在流体上进行三维对流的运动。这些实验与所研究过程的计算机模型相结合。该实验室是我们和其他地球科学系更传统的以样品为导向的实验室的独特补充。它给了学生一个独特的机会来可视化和操作他们以前主要通过讲座学习的过程模型。此外，通过将这些实验集中在一个地方，使用通用的、简单的材料，并将它们纳入本科课程开始时教授的基础课程，新实验室正在帮助学生认识到许多明显不同的地质过程背后的物理学的统一性。＊＊＊
