As a result, federal agencies require phone manufacturers to post information about how much radiation the body might absorb for each model, called its Specific Absorption Rate or SAR.

因此联邦机构要求手机制造商标明人体可能会从每部手机吸收多少放射物，这又被称作电磁波能量(SAR)。

You can get an idea of the relative amounts of radiation various cellphone models emit by looking at their SAR, or specific absorption rate.

It was not until the 1950s that scientists had both good data on the absorption of infrared radiation, and digital computers that could speed through the multitudinous calculations.

直到20世纪50年代，科学家才获得了红外辐射的可靠数据，并有了计算机可以帮助进行海量的计算。

That, in turn, results in an increased absorption of solar radiation by the darker ocean surface, which also contributes to warming.

But the strength of the greenhouse effect depends on the chemical composition of the atmosphere, because the phenomenon is due to the absorption of infra-red radiation by various gases in the air.

The Australian research focused on the thermal effects or specific absorption rate (SAR) of radio frequency radiation - a measure of its actual effects on brain tissue, whereas the earlier study simply looked at electromagnetic radiation levels.
