发射谱线

Finally, in Chapter 4, we discuss the issue of line contamination in bolometer measurement.

最后，我们注意到谱线发射对宽带连续谱的污染是个不容忽视的问题，这在大质量恒星形成区表现尤为突出。

But the energy was concentrated in a spectacularly sharp line in the emission spectrum--in other words, the radiation was exceedingly uniform, consisting of a single wavelength with little contamination from other wavelengths.

但是能量被集中在发射谱中一条非常狭窄的谱线上。也就是说，辐射是极度均匀的，只包含有一个单一的频率，而没有其他频率的干扰。

The Eagle emission nebula, tagged M16, lies about 6500 light years away, spans about 20 light-years, and is visible with binoculars toward the constellation of Serpens.

这幅影像是经过数位合成的彩色影像，原始的影像是三幅透过特殊发射谱线滤光片所拍摄的照片。

There are blue and green emission spectral series in the phosphors activated by three valence ions of Terbium.

三价铽离子激活的磷光体有兰色和绿色两个发射谱线系列。本文分析了这两个系列谱线的强度，随着激活剂浓度而变化的实验结果，发现在激活剂浓度达到一定数量之后，当继续增加激活剂含量时，兰色和绿色发射谱线相对强度的变化规律，和加入敏化剂的结果是一致的。

The light emitted from a Keplerian ring around the objects with strong gravitational field should be affected by Doppler shift, gravitational redshift and deflection of light. The line profiles for a faraway observer are dominated by these effects. In this paper the precise solutions of line profiles for the Keplerian rings in the Schwarz-schild case have been obtained by means of the kinetic equation for photons.

对于一个围绕强引力场物体作开普勒运动的环状发光物，它所发射的光线要受多普勒频移，引力红移和光线偏折等效应的作用，这种作用决定了远处观察者所看到的谱线轮廓，本文利用光子输运方程方法，求出在Schwarzschild度规中的开普勒环所发射的谱线的轮廓的精确解。

By simulating the absorption spectrum of molecule iodine absorption filter ranges from 470nm~550nm, this paper selects the absorption spectrum of molecule iodine absorption filter that satisfies the requirement of frequency discriminator in detecting system and ascertains the center emission frequency of laser emitter.

以基于边缘探测技术的激光雷达监测大气信道和海洋水下信道环境参数为例，通过仿真出碘分子吸收滤波器在470nm～550nm区间范围内的吸收光谱谱线，选择出合适的吸收谱线并确定发射激光信号的中心频率，并在此基础上，给出了满足探测要求的激光发射信号单稳频指标，为实际探测系统的设计奠定基础。

Normally, Lyman-alpha emission is in the ultraviolet part of the spectrum, but Lyman-apha blobs are so distant, their light is redshifted to optical wavelengths .

正常来说，Lyman-α发射谱线为紫外光，但是Lyman-α云球却是红位移到遥远的可见光波段。

Firstly, a group of red.shifts were determined using the emission line info extracted from the observed spectrum; Secondly, the template was red.shifted according to the candidates, and the correlation between the observed spectrum and the redshifted template was measured.

首先，利用提取出的发射谱线信息确定一组红移候选；然后，按这些红移候选将静止模板光谱红移，计算所得光谱与目标光谱的相关值；最后，确定最大相关值对应的红移候选为目标光谱的红移。
