上现蜃景形成的理论分析以及实验再现

Theoretical Analysis and Experimental Reproduction of Superior Mirage

海市蜃楼这种自然现象在古代就被人们发现且有记载,古时候人们将海市蜃楼看作仙境、神迹,随着科学的发展,海市蜃楼真正的成因逐渐被人们了解。海市蜃楼分为上现蜃景与下现蜃景。上现蜃景常出现于海上以及被冰雪覆盖的地方,下现蜃景常出现于热季的沙漠上或冬季暖洋流的海上。本文用光学知识解释了上现蜃景的形成原因,设计实验对激光光路进行模拟验证了理论,进一步在实验上进行了蜃景的再现,最后探讨蜃景在实际生活中的应用。

Mirage,a natural phenomenon,has been discovered and recorded in ancient times,which people had regarded as fairyland and miracle.With the development of science,the real cause of mirage is gradually understood.Mirage is divided into superior mirage and sinking mirage.The superior mirage often appears above the sea and those places covered by ice and snow,while the sinking mirage often appears on the desert in hot season or above the sea with warm ocean current in winter.It will use optical knowledge to explain the formation of the mirage,and design experiments to simulate the optical path and the mirage reproduction,so as to obtain a more detailed understanding of the mirage and explore its application in real life.
