According to the above referred quantitative standard as an HEDC and stabilityrequirement, 1,2,3,4,5,6,7,8-octanitroadamantane, 1,2,3,4,5,6,7,8,9-nonanitroadamantan-e and 1,2,3,4,5,6,7,8,9,10-decanitroadamantane are worth recommending as potentialHEDCs, and this denies the foreigners conclusion obtained from group additivity thatthe PNA with 11 nitro groups is the target compound.

按照前述HEDC的定量标准和稳定性要求，发现1，2，3，4，5，6，7，8-八硝基金刚烷、1，2，3，4，5，6，7，8，9-九硝基金刚烷和1，2，3，4，5，6，7，8，9，10-十硝基金刚烷三种化合物是值得推荐的潜在HEDC，从而否定了国外前人由基团加和法得出的十一硝基金刚烷是PNAs系列最佳HEDC目标物的结论。

Based on the frequencies scaled by 0.96 and the principle of statistic thermodynamics, the thermodynamic properties were evaluated, which were linearly related with the number of nitro and amino groups as well as the temperature, obviously showing good group additivity.

对谐振频率以0.96进行标度后基于统计热力学原理求得它们的热力学性质，探讨了热力学性质随硝基数、氨基数和温度变化的规律，发现有很好的线性关系，体现了很好的基团加和性。

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。
