光谱线

Combining with the temporal and spatial distribution spatial distribution species radiation intensity,the detailed mechanism of the generation of laser induced species radiation was discussed, the continuous radiation comes from the Bremsstrublung emission of energetic electrons ejected from the target and recombination of electron and ion near target, the primary mechanism of atomic excitation and ion excitation in plasma is inelastic collision between the elemental species and high-kinetic energy electron,the model can explain the experimental results qualitatively.

讨论了激光诱导发光的机理，认为等离子体羽中连续辐射背景光主要来自近靶处高能电子的韧致辐射和电子与离子的复合激发，原子和离子光谱线主要由等离子体中高能电子的碰撞传能激发所引起，并用之较好地解释了所观察的实验现象。

Wavelength calibration coefficients were calculated through regression analysis after several ordinal numbers of CCD's pixels corresponding to Mercury-Argon Lamp's spectral lines were measured. The residuals of certain spectral lines were computed using the coefficients measured and the ones from factory, the degree of fitting for regression equation was estimated using the new coefficients. The final results validated the wavelength calibration model.

在测量了多条光谱线对应的CCD像元的序数之后，使用回归分析得到波长定标的系数，连同光谱仪出厂时的波长定标系数，计算出了两组定标系数在给定的一些谱线位置处的残差，并利用实验所得的系数对回归方程进行了拟合优度检验，结果表明波长定标模型是有效的。

Bao. I think he does not know the : quasar physics at all!: A simple reason: astronomers detected redshifts of quasars based on the spectr : al lines emitted from the emission line regions, which are 0.1 to 1 parsec (1p : arsec=3.26 light years) far away from the central black hole. Therefore there : is very little effect from the gravitational redshift!

观察到的类星体的光可在几日内有明显的变化，可见类星体的发光区大小在光日尺度以下，即使你认为类星体的光谱线产生于吸积盘，那么吸积盘的大小须在光日尺度以下才能不相矛盾，请你说出一个你认定的类星体吸积盘的大小尺度与该尺度内所具有的质量，及因此计算出的可忽略的引力红移。
