光谱线

ABSTRACT The development history and current research state of pulsed discharge-excited alkaline-earth Metal Vapor Lasers were reviewed in detail in the paper. After all those multi-mechanism lines region from ultraviolet to infrared had been successfully obtained in our experiments, a consistent model has been build up for longitudinal pulsed discharge excited He-Sr vapor laser.

Had proven according to this theory Urey has discovered the hydrogen isotope deuterium existence, however the Bohr theory's further development encounters the insurmountable difficulty, it is unable to process compared to the hydrogen atom slightly for the complex spot helium atom, also inextricability light spectral line intensity question and non-fetter system's question; The Bohr theory also is only the quantal concept and the classical theory mix, theoretically appears is not very harmonious.

根据此理论证明了尤里发现了氢的同位素氘的存在，然而玻尔理论的进一步发展遇到不可克服的困难，它无法处理比氢原子稍为复杂一点的氦原子，也无法解决光谱线的强度问题和非束缚体系的问题；玻尔理论还只是量子概念和经典理论的混合，理论上显得很不和谐。

Emission in this spectral line shows the upper chromosphere at a temperature of about 60,000 degrees K (over 100,000 degrees F).

In addition,the electron density of plasmas were calculated from measured stark broadening of emission spectral line respectively, the effects of the additional voltage on the electron density and the spatial evolution property of the electron density were finally discussed according to the experimental results.

此外，由发射光谱线的Stark展宽计算了等离子体电子密度，并由实验结果讨论电子密度随外加电压的演化特性和空间演化特性。

The intensity of grating diffraction spectrum is obtained by the Fourier series expansion of the transmissivity function. Finally, the design feasibility is analyzed by comparing the minimum signal spectral intensity with the maximal spectral intensity of the background light and the noise intensity.

The influence of different soil spectral line on plant canopy and greenness assessment was discussed.

讨论了不同土壤光谱线对绿度及植被覆盖度估计的误差。

In his later years Lenard studied the nature and origin of the lines of the spectrum.

后期，莱纳德又研究了光谱线的本质，发展了里德伯、海因里希·凯泽和卡尔·伦格的研究成果，他们提出金属的光谱线可以分为两类或更多类连续光谱，并且这些谱系的波长之间存在明显的数学关系。

In the simplest type of splitting, somewhat misleadingly called the "normal" Zeeman effect, because it was the first to be explained within the classical theory, a single line splits into three lines when observed in a direction perpendicular to the magnetic field.

最简单的分裂类型，从垂直于磁场的方向观察，一个光谱线分裂成三个光谱线，这种类型多少有点误导地被成为&一般&塞曼效应，因为它在经典理论中第一次解释了这种现象。

With Death guitarist Schuldiner adopting vocal duties, the band made a major impact on the scene.

随着死亡的吉他手Schuldiner接受主唱的职务，乐队在现实中树立了重要的影响。

But he could still end up breakfasting on Swiss-government issue muesli because all six are accused of nicking around 45 million pounds they should have paid to FIFA.

不过他最后仍有可能沦为瑞士政府&议事餐桌&上的一道早餐，因为这所有六个人都被指控把本应支付给国际足联的大约4500万英镑骗了个精光。
