本文研究声重波在垂直切变风场中传播时谱结构的改变。
In this paper, the variation of spectral structure of acoustic gravity waves (AGW's) propagating through a region of vertical wind shear is investigated.
他们还表示在中微子能谱中没有发现下沉,这种下沉意味着在切伦科夫辐射时的能量丢失。
They also say there were no dips in the neutrinos' energy spectrum that would imply that they were emitting Cherenkov-like radiation.
表明这一迹象的是撞击掀起的尘土中显示的红外线光谱中的一些谱线,其频率与水分子能量激发时所发出光线的频率相应。
The telltales are specific "lines" in the spectrum of infra-red light from the plume. These correspond to the frequencies of light given off when water molecules are energetically excited.
And what you see when we see it with our eye, which is all the wavelengths, of course, mixed together, is whichever those wavelengths is most intense. So, when we looked at the individual neon lines, it was the orange colors that was most intense, which is why we were seeing kind of a general orange glow with the neon, which is different from what we see with the hydrogen.
当你们用眼睛看时,当然看到的是全波长,是混在一起来,看到的是最强的那些波长,当我们看单个氖谱线时,橙色是最强的,所以我们看氖光整体是橙色的,这和氢气是不一样的。
First there was the observation by Michelson who back in the late 1880s had done very precise interferal metric measurements of the hydrogen lines and had observed that the 656 nanometer line 3 associated with the transition of n equals 3 to n equals 2 was, in fact, a doublet.
首先是麦克逊,在1880年底的观察,他以公制单位对氢原子的光谱线,作了准确的,无其他因素干扰的,测量,发现当n值由3变为2时,会同时得到波长为656纳米的谱线3,实际上是有两条线。
