The pigments synthesized from 2, 7-diaminoflurenone consistently show better photosensitivity than that containing anthraquinone. A plot of the E1/2 values against the Hammett constant σ was obtained for the pigments which have different substituents in the anilide ring. The plot reveals that neither a strong electron-releasing group, such as methoxy, nor a electron-withdrawing group, such as nitro-group, enhances the sensitivity of the photoreceptor in which these pigments are used as CGL materiel.
芴酮类偶氮染料的光敏性优于蒽醌类偶氮染料,其偶合基酰胺芳环取代基为强的给电子基团或强的吸电子基团时都不利于其光敏性的提高,只有当取代基基团为氯时其表现出最好的光敏性,这一结果与Law等人的研究结果相同。

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。
