Since chlorophyll plays such a vital role in photosynthesis, it has been studied extensively by plant physiologists in an effort to determine how it accomplishes its transformation of carbon dioxide and water into food.

由于叶绿素在光合作用中的重要地位，植物生理学家已经对叶绿素作了广泛的研究，旨在确定二氧化碳和水是怎样通过叶绿素合成有机物的。

The dry atmosphere consists almost entirely of nitrogen (78.1% volume mixing ratio) and oxygen (20.9% volume mixing ratio), together with a number of trace gases, such as argon (0.93% volume mixing ratio), helium, and radiatively active greenhouse gases such as carbon dioxide (0.035% volume mixing ratio), and ozone.

干大气几乎完全由氮（78.1%的体积混合比）和氧（20.9%的体积混合比）构成，还包括一些微量气体，如氩（0.93%的体积混合比）、氦，以及对辐射起作用的温室气体如二氧化碳（0.035%的体积混合比）和臭氧。

John Tyndall wrote in 1861 that slight changes in the amount of any of the radiatively active constituents of the atmosphere—water vapor, carbon dioxide, ozone or hydrocarbons—may have produced "all the mutations of climate which the researches of geologists reveal … they constitute true causes, the extent alone of the operation remaining doubtful."
