What we've done is we've engineered those dyes to selectively absorb infrared light and also convert that light into electricity.

我们做的是让这种染料有选择性地吸收红外线，同光电转化。

Consequently, the cultural exchange becomes unidirectional, with visitors observing rather than participating, and assimilating only what is selectively presented.

此，文化交单向，参观者观察而不是参与，只吸收选择性呈的东西。

While dyes and pigments produce colour by selectively absorbing light, structural colors are produced when light interacts with the microscopic structure of a material.

染料和颜料通过选择性吸收光来产生颜色，而结构色是在光与材料的微观结构相互作用产生的。
