韩长明 主持 “红外寻的演示枪”是用于讲述凸、凹透镜原理应用方面的演示实验装置．其利用面透镜会聚和四透镜发散的基本原理，组成了一个简单的红外搜寻瞄准系统，能自动搜寻前方一定立体空间内任意位置的所有燃烛，并以０．４ｍｍ口径的水枪将其逐个准确摧灭． “红外寻的演
Han Changming presided over the “Infrared Seeking Demonstration Gun” is a demonstration experiment device for the application of convex and concave lenses. It uses the basic principle of the convergence of the surface lens and the divergence of the four lenses to form a simple infrared search sighting system that can automatically search all the candles in any position in front of a certain solid space and use the water gun of 0.4 mm diameter to accurately measure them one by one. Destroy. "Infrared search
