    双解例句

    noun(名词)
    1. （尤指星体）反照率

      Open water is one of the substances with the lowest albedo that we have on Earth.

      开阔的水面是地球上反照率最低的物质之一。

      Scientists detected what could be a 2.5 percent decrease in Earth's albedo over the past five years.

      科学家们发现在过去五年中地球的反照率可能下降了 2.5%。

    2. 反照率效应

      The albedo effect – the reflection of 80% of the sun's heat by the snow and ice – keeps temperatures in the region cool.

      反照率效应，即冰雪反射80%的太阳热量，使该地区的温度保持凉爽。

      As the ice shelves melt, more trees grow, which might actually make things worse by reducing the albedo effect.

      随着冰架融化，更多树木生长，这可能会降低反照率效应，使情况变得更糟。

    小知识

    Albedo refers to how reflective and bright something is. Snow has a high albedo, which is why skiers wear sunglasses and sunscreen.

    Technically speaking, the albedo of an object is a ratio. It compares the amount of light hitting the surface of the object to the amount of light that gets reflected back. The more light reflected, the higher the albedo. Scientists often use this word in reference to the surfaces of planets and other reflective objects in the night sky. Albedo comes from a Latin word for “white.”
