摘要 针对传统蜃景演示装置操作复杂或成像缓慢等不足，本研究设计并制作了一种基于甘油温度梯度场的新型蜃景演示装置。该装置采用上端 U 型加热管加热、下端半导体制冷片制冷的方式，在甘油介质中快速构建起稳定的温度梯度场。光线在该温度梯度场中发生全反射，从而呈现出清晰的上现蜃景现象。本装置具有现象明显、操作简便、成像迅速等特点，能够直观演示蜃景的形成过程，有助于加深对折射、全反射原理及蜃景成因的理解。
Abstract: To address the limitations of traditional mirage demonstration devices，such as complex operation or
slow imaging，this study designed and developed a novel mirage demonstration device based on a glycerol
temperature gradient field． The device rapidly establishes a stable temperature gradient within the glycerol
medium by employing a U-shaped heating tube at the top and a semiconductor cooling plate at the bottom．Light
undergoes total reflection within this temperature gradient field，thereby producing a clear superior mirage
phenomenon．This device is characterized by its distinct phenomenon，simple operation，and rapid imaging．This
device is characterized by clear phenomena，easy operation，and fast imaging． It provides an intuitive
demonstration of mirage formation and enhances understanding of the principles of refraction，total internal
reflection，and the underlying causes of mirages．
