叙述了一个计算机辅助口腔下颌运动的显示与处理系统。此系统包括用下颌运动轨迹描记仪获取口腔下颌运动轨迹的数据及对其进行校正、分离等处理和通过轨迹放大、移动、测量等显示手段辅助医生诊断和研究。并且在此系统中建立了口腔下颌骨的三维模型，可以形象再现口腔下颌运动过程。此系统既辅助医生的临床诊断，又可以用于口腔下颌运动的教学和科研工作

The paper introduces a processing and displaying system of mankind’s mandibular movement. It includes gaining data of mandibular movement by a tracing recorder, data processing, and data displying. Data processing includes calibrating, separating. Data displaying includes zooming, moving and measuring. A 3D model of mankind’s mandibular is built in our system, therefore, a realistic mandibular movement can be gained. These functions all assist medical doctors to diagnose. Certainly the system is helpful for the education and researching of mandibular movement.
