A roof or a wall with higher-than-normal reflectance will absorb less sunlight.

反射率高于正常值的屋顶或墙壁吸收的阳光较少。

This heavily modifies its physical properties, chemical compositions and mineralogical features, and in turn, the optical reflectance spectra of the moon, said the paper.

这严重改变了月球的物理性质、化学成分和矿物学特征，进而改变了月球的光学反射光谱。
