| 1. | An atomic emission spectrum contains light of only certain specific wavelengths
一个原子发射光谱包括一种特定波长的光。 |
| 2. | The colors seen in fireworks are also due to atomic emission spectra of various elements
烟火中的颜色也是由不同元素的原子发射光谱形成的。 |
| 3. | In contrast only a few widely spaced lines are seen in hydrogen ' s atomic emission spectrum
相反相成，氢原子发射光谱中则只能看到少量的间隔很大的线条。 |
| 4. | Each element has a unique atomic emission spectrum with different numbers and colors of lines
每个元素都有一个独特的原子发射光谱，拥有不同的线条数量和颜色。 |
| 5. | For example , neon ' s atomic emission spectrum consists of dozens of closely spaced lines , many of which are red or yellow
比如，氖的原子发射光谱包括许多紧密间隔的线条，其中许多都是红色或黄色。 |
| 6. | Hence , the spectrum is called a line spectrum ; it is also called an atomic emission spectrum , since it is produced by emission of light from excited atoms
因此，这个光谱也被称为线光谱，也被称为原子发射光谱，因为它是由被激活的原子发出的光产生的。 |
| 7. | Atomic emission spectrum and phase properties of the field in some atom - field coupling systems are investigated . effects of quantum interference between two different transition pathways on atomic emission spectrum and phase properties of the field are discussed
本文研究了光场与原子相互作用系统中原子的发射谱和光场的相位性质，讨论了原子不同跃迁通道间的量子干涉对原子发射谱和光场相位性质的影响。 |
| 8. | First the emission spectrum of an atom in a grey - body cavity is stuided . the influences of the incident field photon - number distribution , the cavity absorptivity and the system temperature on the atomic emission spectrum are discussed in detail . it is found that the influence of cavity radiation on the atomic emission spectrum could be reduced through diminishing the absorptivity of the cavity and lowering the temperature of the cavity
我们首先研究了灰体腔中二能级原子和型三能级原子的发射谱，详细讨论了入射场光子数分布、腔体吸收系数以及系统温度对原子发射谱的影响，指出在实验上可以通过减小腔体吸收系数、降低系统温度来减小腔体辐射对原子发射谱的影响。 |
| 9. | Finally we focus our attention on studying the emission spectrum of two atoms driven by a single - mode field in an ideal cavity . we showed that the atomic emission spectrum is insensitive to the phase of field for the two atoms initially in the coherent superposition state tf / = v2 / 2 ( j + , - ) h ? + } ) , when the two atoms is initially prepared in ( fs * } = cos ( 0 / 2 ] + , + ) + sm ( 0 / 2 ) ei ' p - , - ) , the atomic emission spectrum is associated with not only the field photon - number distribution and the atomic populations , but also the phases of the field and the atomic dipole
接着考察了好腔中由单模量子场驱动的双原子发射谱，结果表明初态为的双原子发射谱与驱动场的相位无关；而初态为的双原子发射谱不仅与光场的光子数分布以及原子的布居数有关，而且依赖于光场的相位以及原子偶极矩的相位，并且在适当的条件下，压缩真空场可将双原子俘获在相干叠加态。 |
