specific absorption

基本解释

Specific gasses have very specific absorption line patterns making their presence very easy to detect.
特定的气体将有特定的吸收光谱，这使得他们很容易识别。
You can get an idea of the relative amounts of radiation various cellphone models emit by looking at their SAR, or specific absorption rate.
你可以通过查看不同手机型号的吸收率，来了解手机的辐射。
Radiofrequency exposure limits for mobile phone users are given in terms of Specific Absorption Rate (SAR) – the rate of radiofrequency energy absorption per unit mass of the body.
对于比吸收率（人体每单位生物组织的射频能量吸收率）已给出适用于移动电话用户的射频接触限值。

The rate at which energy is absorbed by the body when exposed to RF is referred to as the specific absorption rate, or SAR.

In addition, according to Adair, the whole heated debate about specific absorption rates, or SAR, is beside the point because the SAR is not a measure of biological insult.
