很多人装修好房子后不久,就看厌了家里的墙壁,想更换墙上的图案,可重新装修,很花时间又费钱,而且装修材料有毒,会挥发有害气体,危及人体健康,因此他们非常烦恼。要是墙壁能自动变色就好了,所以我想发明一种节能环保的变色墙壁。 Not long after many people renovated their houses, they looked tired of the walls at home and wanted to change the patterns on the walls. They could renovate their houses and spend a lot of time and money on them. Moreover, the decoration materials are toxic, harmful gases are emitted and endanger human health, so they Very annoyed. If the wall can be automatically discoloration just fine, so I would like to invent a kind of energy-saving environmental protection of the color changing wall.
