And that is measured as a macroscopic cross section of absorption thermal divided by the integral of all energies in terms of absorptions.

那是被测量的，作为吸收热能的，宏观横截面，除以全部的，吸收的能量的乘积。

We can then look at uranium 238 which has a relatively low absorption thermal energy range and essentially has no fission cross section which is why we call uranium 238 a fertile atom.

我们能看看铀238，它有一个，相对低的吸收热能范围，基本上没有裂变横截面，那就是为什么我们称铀238为可转换核素。

Based on the photoelectron character, the factor effecting on the creation of photoelectron was analyzed in light absorption excitation and thermal excitation.

针对晶体中光电子涨落的特点，分析了光吸收激发和热激发中影响光电子产生的因素。

In general, the solar thermal has greater flexibility when used with co-generation systems, such as combining production of power and thermal for desalination or absorption cooling.

FORBES: Thailand Opens The First of Fifteen Solar Thermal Plants Using Solarlite Technology

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.
