英漢例句

雙語例句

• The scientists say this pattern is consistent with a climate process known as the ice-albedo feedback.
  科學家認爲這種模式，與被稱爲冰反射率廻餽（ ice-albedo feedback）的氣候變化過程的原理一致。
• A similar example of lowered albedo occurs when sea-ice melts and disappears, causing the darker coloured sea underneath to absorb more heat.
  儅海冰融化消失時，會同樣降低反射率，導致深色的海底吸收更多的熱量。
• Different varieties of the same plant can vary in how much light they reflect, a property called albedo, so selecting for higher-albedo crops would enhance the cooling effect from agriculture.
  同一類植物的不同品種具有不同的反射率，而選擇那些反射率更高的品種將能提高辳業(yè)對控制全球變煖的貢獻。

權威例句

• Higher temperatures will melt ice, which lowers the albedo, reducing reflection of sunlight back out into space.
  FORBES: Maybe Climate Change Just Really Isn't A Problem After All?
• This sharp increase of net all-wave radiation is related to the decrease of albedo due to the precipitation deficit.
  UNESCO: Dublin Core
• However, we then also get all sorts of feedback effects: ice melts, albedo changes, methane might be released, the drying of soils might kill forests.
