创新性模拟海市蜃楼现象
|
摘要
利用定影粉配制成浓度连续变化的溶液,来模拟大气中密度连续变化的空气,实验获得了良好的海市蜃楼"上现蜃景"效果;另外,用不同浓度的蔗糖溶液配制成的梯度溶液,实现了"两个上现蜃景"的效果。通过对这两种体系的成像效果的研究,加深了对海市蜃楼这一神秘自然景观的认识和理解。
By employing an aqueous solution with concentration gradient prepared with fixer powder to simulate the open air with continuously variable densities in the atmosphere,excellent simulation of the natural superior mirage phenomenon was achieved. Moreover,by using the gradient solution prepared with sucrose aqueous solutions with different concentrations,the double superior mirage effect was successfully obtained. Through the study on the imaging effects of both the simulation systems,it deepens the cognition and understanding of the mysterious natural mirage phenomenon.
