海市蜃楼演示装置的改进

摘要

Currently ,the mirage demonstration device requires many people to operate .The ex-periment period is too long and the phenomenon is unstable .Aiming at these problems ,the device had been improved by adding a 3-layer impermeable film and a slow pumping device .The demonstration effect of improved device was intuitive ,clear and stable .%目前实验室的海市蜃楼演示装置需要多人操作，且演示周期长，实验现象不稳定。针对这些问题，对该装置进行了改进，增加了3层隔水薄膜，通过抽水机向装置内缓慢注水。改进后的装置演示现象直观、清晰，且实验现象保持的时间较长。
