Abstract : in this paper , the preparation of the catalysts for the oxidation of fluorene to fluoreone is studied . the influences of the dipping time , calcining temperature , calcining time and the air quantity during the calcination are discussed 文摘:研究了用工业芴气相氧化制取芴酮的催化剂制作条件，考察了浸渍时间、煅烧温度、煅烧时间和煅烧空气量对催化剂制作的影响
In the third chapter , the organic single - layered photoreceptors were prepared , which consisted of polycarbonate matrix containing dispersed n , n ' - diethyl - 4 - aminobenzaldehyde - l - phenyl - l ' - ( a - naphthyl ) - hydrazone ( bah ) and 2 , 4 , 7 - trinitryl - fluorenone ( tnf ) as bipolar charge transport materials ( ctm ) , as well as tiopc as charge generation material ( com ) . the influence of organic electron transport material on the photosensitivity in the photoreceptors was investigated 在论文的第三章，我们研究了有机电子传输材料2 ， 4 ， 7 -三硝基芴酮( tnf )对有机单层光电导体( tiopc bah pc体系)光敏性能的影响，发现少量的tnf ( tnf bah 0 . 005 )可使得单层有机光电导体的光敏性能大幅度增强，并探索了其影响因素和微观机理。
1 . two kinds of azo pigments with excellent photosensitivity , named as flurenone bisazo ( f - azo ) and oxazole bisazo ( o - azo ) , are synthesized . the preparation of organic photoconductive blended materials and their photoconductivity in single - layered photoreceptors made from f - azo / titanium oxide phthalocyanine ( tiopc ) composite and o - azo / tiopc , respectively , are investigated 合成了芴酮基偶氮( f - azo )与?唑基偶氮( o - azo )两种光敏性优良的偶氮化合物，并以此制备了芴酮基偶氮酞菁氧钛和?唑基偶氮酞菁氧钛复合光电导材料体系及其单层光电导体。
The explanation of this inconsistency is found in a note by odd tablet at the end of chapter 13 in one of the manuscripts , in which he says that he " ordered " xueqin to excise a passage of eight or nine pages describing qin - shi ' s suicide in the celestial fragrance pavilion - presumab 珍 because he found it too upsetting 在某个抄本第十三回的末尾，畸芴叟在注解中解释了为什么会出现文字的前后不一，他说是他命令雪芹删除了第八、九页关于秦氏天香楼自杀的描述，大概是因为他觉得这段文字令人心烦意乱。
Based on the above theory , the fluorinone - based azo was used to prepare the single - layer photoreceptors with fluorinone - based azo / tiopc composites in chapter iv , experimental data indicated that the photoconductivity of fluorinone - based azo / tiopc composite photoreceptors was improved in comparison with that of chlorodiane blue azo / tiopc composite photoreceptors , the amelioration was attributed to the more pronounced electron - acceptor characteristic of fluorinone - based azo , these results further confirmed the mechanism proposed for the synergetic enhancement and complementary effects in azo / tiopc composite systems 根据激发态下部分电荷转移机理，本论文第四章选择具有电子受体特征比较明显的芴酮基偶氮制备了芴酮基偶氮/酞菁氧钛复合单层光电导体，研究结果发现复合材料的光导性能比氯丹蓝偶氮/酞菁氧钛复合体系有所提高，进一步证实了偶氮/酞菁复合材料光导性能的协同增强效应的内在原因。
Abstract : artificial neural networks has been applied to simultaneous determination of fluorene and acenaphthene by ultraviolet spectrophotometry . after compared the results of the synthetic samples obtained from the method above mentioned with those from partial least squares ultraviolet spectrophotometry , it shows that satisfied prediction can be obtained by them 文摘:用人工神经网络-紫外吸光光度法不经分离同时测定芴和苊，并与偏最小二乘-紫外吸光光度法比较.对合成样品进行分析.结果表明，人工神经网络法同偏最小二乘法一样能获得满意的分析结果
