查询词典 emission line

At the eclipses of 1868 and 1869, observed from Siam and from the United States, respectively, the first coronal emission line was detected: about 25 years later, it was said to be from the element 'coronium', by analogy with the prior discovery of helium.

Based on these properties mentioned above and the standard model of AGNs, we prove that the nature of the systematical difference between Mσ and MH is that Mσ represents the mass in broad emission line region, while MH represents the mass in the continual emission region (r≤ra and ra＜＜rb) which is near the innermost stable orbit around the black hole.

以上述的这些性质和活动星系核标准模型为基础，我们证明了这两种方法所得的黑洞质量Mσ和MH之间的系统差异是因为Mσ描述的是宽发射线区的黑洞质量，而MH描述的是黑洞周围在最内层轨道附近的连续发射区的质量。

The modified expression of the broad emission-line profiles ire derived for the outflow kinematics model of the BLR driven by the radiation pressure. Taking into account the difference between the two lines HeI λ5876 and Hβ, it is shown the fact that the observed line width of HeIλ 5876 is broader than that of Hβ cannot be explained by the popular outflow BLR model evoked by W. G. Mathews. For comparison, line profiles of the gravitational infall model and orbital disk model are also calculated; the later is in good agreement with the observations Thereupon, conclusion is reached that the gravitational infall is an important process in the real BLR gas motion.

1推导了辐射压加速宽线云团径向外流，以及引力下落和转动等BLR运动学模型的谱线轮廓表达式，并考虑到光致电离计算表明的云团本身对Hβ和HeIλ5876谱线的辐射差异，用数值方法计算了它们的谱线轮廓，发现普遍流行的辐射加速气体外流模型不能解释HeIλ5876线宽大于Hβ线宽的观测事实，而引力下落模型则可以较好地解释观测，因此我们倾向于认为、径向内流运动很可能是BLR内的发射线云团真实运动的一个重要成分。

Through investigating the effect of glow discharge parameters such as voltage,current,preburn time and integrating time on the precision and intensity of the emission line,the parameters of analyzing stainless steel were optimized and a new method for the determination of 11 elements in stainless steel by direct current glow discharge -optical emission spectrometry was established.
