摘要
《物理化学》中化学动力学一章讨论化学反应速率和机理。在此章中 ,有一些化学反应动态过程的理论处理 (如碰撞理论和过渡状态理论 )是很难在黑板上形象地加以描述的。 3DSMAX提供了能将这些概念和理论以及反应动态过程在三维空间加以形象描述和模拟的有力工具。本文介绍了用 3DSMAX动画设计技术 (放样制作造型、布尔运算、材质设计和动画制作 )制作模拟双分子反应过程的位能面MCAI课件的过程。在此课件中 ,一个由三原子组成的双分子反应体系的位能面被形象地表达出来。反应体系的代表点从山谷R沿反应途径爬过鞍点Q后落入另一山谷P中 (R -Q -P线就代表反应途径 )。学生可以用此课件从各个不同方向观察位能面图。3DSMAX动画制作技术改变了传统的数学模式 ,使物理化学教学内容更加生动和直观 ,同时也更好地发挥了多媒体技术在化学教学中的作用。
In the Physical Chemistry course, Chemical Kinetics is concerned with the rates of chemical reactions and mechanisms by which reactions occur. There are some theoretical treatments of the dynamic process of reactions, for example the collision theory and the transition state theory, in this chapter. It is difficulty to describe these dynamic processes on the blackboard figuratively. The 3DS MAX can be provided three dimensional animation design technique. It is convenient to describe some concepts and theories that we have refereed to, and to simulation the dynamic process of reactions in the three dimensional coordinate.In this paper, it is introduced that the manufacture process of the MCAI course ware of the potential energy surface that is possible to simulate the process of a bimolecular reaction by using 3DS MAX animation design technique (Got up sculpt by lofting, Bool algerbra, Material designing, Animation designing). In this MCAI course ware, the potential energy surface of a bimolecular reaction system that is composed of three atoms has been described figuratively. In the figure, the system will travel along the valley (R), over the saddle point (Q), and down into the second valley (P). The reaction path is represented by R Q-P line. The students may be observed the potential energy surface diagram in several directions, so they will interest to study the Physical Chemistry.
