利用材料的热色现象,可使混凝土具有随季节发生颜色变化的功能.例如,HgI_2),Agl和Ca_2Hgl_4的颜色随温度变化而变化,这是由于在温度变化时晶体结构受光作用发生改变而造成的.再如,在Cholesteric液体里选择离散光的波长发生变化,这种变化也是由于温度变化引起的.因为颜色随温度变化是可逆的,所以可以对混凝土结构进行季节颜色控制.对于前例的情况,材料能与水泥混合,而对后例的
Using the thermochromism of the material, the concrete can have the function of changing color with the season. For example, HgI_2), the color of Agl and Ca2Hgl_4 changes with the temperature, which is caused by the change of the crystal structure due to the effect of light upon temperature change. For example, the wavelength of the selected discrete light in the Cholesteric liquid changes, this change is also caused by the temperature change. Because the color is reversible with the temperature change, the color of the concrete structure can be controlled seasonally. For the previous case Materials can be mixed with cement, but for the latter
