The result showed that the photoconductive material of binary blended composite was not found to be used in laser beam printers. The expert group, organized by Science Committee of Zhejiang Province, considered that the achievement was based on our own technology, and was the achievement with new ideas and high technology which reached the international level. 2. In order to broaden the spectrum response range for photoconductors, we blended TiOPc with monoazo pigment (AZO-1), double azo pigments (AZO-2, AZO-3 and AZO-4) based on benzidine as bridge group, double azo pigments (AZO-5, AZO-6, and AZO-7) based on 2, 7-diamino-fluorenone as bridge group respectively.

Three part of research works had been carried out in the dissertation. The first part: a kind of multidentate amine modified silica gel was synthesized through the following steps:(1) introduce the amino groups onto the surface of silica-gel by the treatment of surface silanol groups withγ-aminopropyl trimethoxy silane;(2) michael addition of excess trihydroxymethyl propyl triacrylate to amino groups on the silica gel surface;(3) amidation of the unreacted double bonds of TMPTA on the surface of TMPTA modified silica gel with diethylenetriamine;(4) the multidentate amine modified silica gel was finally obtained by the reaction of amino groups on the surface of DETA modified silica gel with double bond of butyl acrylate.

本论文进行了三部分研究工作，第一部分：通过多步反应对硅胶进行改性合成了一种多齿胺改性硅胶配体，合成过程如下：1通过γ-氨丙基三甲氧基硅烷与硅胶表面的硅羟基反应，使硅胶表面带有氨基；2利用硅胶表面氨基与过量的三羟甲基丙烷三丙烯酸酯发生Michael加成反应；3利用二乙烯三胺与TMPTA改性硅胶表面未反应的双键发生反应使硅胶表面氨基化；4最后用丙烯酸正丁酯与DETA改性硅胶表面氨基充分反应成功合多齿胺改性硅胶配体。

Double Patenting:" A nonstatutory obviousness-type double patenting rejection is approptiate where the conflicting claims are not identical, but at least one examined application claims is not patentably distinct from the reference claim because the examined application claim is either anticipated by, or would have been obvious"

对于DOUBEL PATENTING，我的另外一个理解，其实质与显而易见性差不多，但是因为是同一个专利权人，所以美国给同一个专利权人就实质同一发明获得多个专利权开了个口子，只要专利权人让所有专利同一天到期即可。

The electron impact mass spectra of the chemical products modified by 2-amino-2-methylpropanol of the fatty acids in sunflower oil were analyzed; the allocation rule for the carbon double bonds in olefinic acids was discussed and the location of the carbon double bonds of the fatty acids in sunflower oil was confirmed.

The fiber length has only little influence on the basic density within the growth rings, and significant correlation at 0.01 levels was found between the basic density and the fiber length among the different rings. Only slight negative correlation was found between the basic density and the fiber width within the growth rings, but significant positive correlation at 0.01 levels was indicated between the basic density and the fiber width among the growth rings, contrary to that of fiber length. It was demonstrated that significant positive correlations at 0.01 levels between the basic density and fiber double wall thickness, fiber length to width ratio and double wall thickness to diameter ratio, significant negative correlations at 0.01 levels between the basic density and fiber diameter and diameter to width ratio, only slight negative correlation between the basic density and fiber width both in the same growth rings and among the different growth rings. No significant correlation was found between the basic density and the vessel morphological features, nor was the tissue proportion in the same growth rings. But among the different rings, it was found there was significant positive correlation at 0.01 levels between the basic density and the fiber proportion among the different rings, and significant negative correlation at 0.01 levels between the basic density and vessel-elements proportion and ray proportion, only slight negative correlation between the basic density and the parenchym proportion. Significant or no significant negative correlation was found between the basic density and the microfibril angle in the same growth rings, but significant negative correlation was found between the basic density and the microfibril angle among the different growth rings.

生长轮内纤维长度对基本密度的影响不大，而在不同生长轮间纤维长度与基本密度达极显著正相关，纤维宽度与此相反，同一生长轮内纤维宽度与基本密度极显著负相关，不同生长轮间只有微弱负相关；基本密度与纤维双壁厚、长宽比、壁腔比在生长轮内和生长轮间均呈极显著正相关，而与胞腔直径、腔径比均呈极显著负相关，仅与纤维宽度呈微弱的负相关；导管形态对基本密度的影响不显著；同一生长轮内组织比量对基本密度的影响也不显著，但不同生长轮间基本密度与纤维比量呈极显著正相关，与导管比量和木射线比量呈极显著负相关，与轴向薄壁细胞比量仅呈不显著负相关；生长轮内基本密度与微纤丝角呈显著或不显著负相关，但在生长轮间这种负相关达到极显著水平。
