装有洗过水果的水的盆中,有好几只蚊子之类的飞虫的尸体,而另一个盛着净水的盆里,却什么都没有。蚊子为什么要到水面上来呢?为什么有着“水上漂”轻功的蚊子,会溺死在水中呢?那么蚊子如何拥有“水上漂”的轻功呢?“超疏水性”究竟是个什么东东?轻功为什么失效了?表面活性剂能使表面张力显著下降,浸润性增加,湿了的蚊子腿失去了疏水性,蚊子沉入水中溺亡。
There was a body of flying insects, such as mosquitoes, in the pots filled with washed fruits, and in the other basin filled with purified water, nothing was left. Why do mosquitoes come to the surface? Why do mosquitoes with “floating on water” light drowns in the water? How do mosquitos have “light drifting” dodge? “What is superhydrophobic?” Dongdong? Why dodge failed? Surfactants can significantly reduce the surface tension, infiltration increased, wet the mosquito legs lost their hydrophobicity, mosquitoes drowned into the water.
