The present paper highlights the chief, results of experimental studies recently carried out in the author's laboratory on the stimulatory effects of low level radiation on immunity.

本文扼要地叙述了近年来有关低水平辐射刺激免疫功能的主要实验研究结果。

Collaborating with Princeton researcher Robert Dicke, the pair confirmed Dicke's hypothesis that the original big bang left behind low-level radiation detectable throughout the universe.

他们与普林斯顿大学的研究者罗伯特·迪克合作，验证了迪克提出的假设，也就是最初的大爆炸使得整个宇宙都充满了可以检测到的微弱辐射。

As the capacity of the atmosphere to absorb infrared radiation increases, the radiating level and the temperature of the surface must rise.

随着大气吸收红外辐射的能力增加，地面的辐射水平和温度必须上升。

In any CT scan, the radiologist determines the required level of radiation.

So what we'll do is this problem here, which is let's calculate out what the wavelength of radiation n would be emitted from a hydrogen atom if we start at the n equals 3 level and we go down to the n equals 2 level.

我们来做这个问题,让我们来计算一下,从n等于3到,等于2能级氢原子辐射的波长是多少。
