【摘要】 利用多个CCD摄像头代替实验者"眼睛"观察和记录实验的全过程,具有实验过程现象能重复查看、关键时间节点事件与仪表数据同屏同步显示等特点。文中将CCD图像传感技术和视频存储技术应用到外压容器失稳传统实验教学中,阐述了实验系统的构建,并表明对实验结果的精确判定与分析具有独到的效果。更多还原

【Abstract】 Instead of the eyes of the experimenters to observe and record the whole experimental process,Multi- CCD webcams hold to re- appear the experimental phenomena,to show the real- time synchronous acquisition of the key event or data. In this paper,CCD image sensing and video storing technology were introduced the traditional experimental teaching of the external pressure vessel. The experimental system was also constructed in detail,and the results illustrate the accuracy and multi- functions of the experimental system.更多还原
