光谱斜率

这17个PG类星体中的绝大部分表现出光谱斜率和静止坐标系5100（？）处连续谱流量的反相关。

Most of these 17 PG QSOs show anti-correlation between the spectral slope and the rest-frame 5100 (?) continuum flux .

活动星系核在光学波段的光度及光谱斜率变化

AGN Variability and Spectral Slope Variability in the Optical Band

我们得到了活动星系核在B、V波段合理的光变曲线以及光谱斜率和光度之间的正相关性。

We get reasonable light curves in B and V bands and find a positive correlation between variability and spectral slope .

本文中我们利用盘不稳定模型和星爆模型的基本思想，模拟活动星系核在光学波段的光度和光谱斜率变化，并将模拟的结果和观测进行比较。

In this paper , using disk-instability model and starburst model , the AGN optical variability and spectral slope variability are simulated and confronted with observations .

计算了光谱斜率和红外光度，同时从红外及射电幅射得出了中心星质量损失率及质量损失历经时间。

The spectral slopes , infrared luminosities and mass loss rates of central stars , as well as the mass loss times from infrared or radio radiation are calculated .

褐飞虱为害后稻株光谱的红边斜率和红边面积也分别与虫量存在极显著相关。

The red edge slope ( D λ red ) and red edge area ( Sred ) of the reflectance also significantly correlated with the number of nymphae .
