When the mixture of bacteria strain MH and fungi strain Cladosporium is used, the extent of diesel biodegradation is significantly increased by 80% after five days; Diesel pollutants in aqueous solution can be completely removed by synergistic use of these MH and Cladosporium; The observed synergistic effect is closely related to the aromatics-resistance of the fungi strain Cladosporium, which in turn favors the growth of the MH.

The organoboron compounds in this paper are based on triarylboranes, boronic acids and boronic esters. The structure-property relationship and sensing mechanism are elucidated. Organoboron compounds as Lewis acid can be used as fluoride probe with high sensitivity and selectivity because they have a unique LUMO in which the π-conjugation is divergently extended through the vacant p-orbital of the boron atom. The complexation of the boron π-electron systems with fluoride ion would interrupt the π-conjugation extended through the boron atom, causing the change of photophysical properties.

介绍了基于三芳基硼化合物、硼酸和硼酸酯的有机硼化合物在氟离子检测中的应用，评述了这些化合物的结构和检测性能之间的关系，讨论了检测机理，即有机硼化合物中硼原子空的p轨道使其作为路易斯酸能够选择性地结合氟离子，硼原子与氟离子的结合破坏了硼中心与芳香取代基的p-π共轭，引起有机硼化合物光物理性质的变化，从而实现对氟离子的高选择性检测。

The introduction of methoxyphenyl or fluorenyl endows significantly enhanced electron-accepting capability,and the LUMO energy level decreases from-3.50 eV of 1a to-...

同时，大尺寸芳香取代基的引入有效抑制了由于分子聚集而引起的荧光淬灭，使三亚吡嗪化合物的荧光量子效率从化合物1a的0.23提高到化合物1b的0.81和化合物1c的0.87。

结果发现，芴和甲氧基苯芳香基团的引入使三亚吡嗪化合物的接收电子能力显著提高，LUMO能级从化合物1a的-3.50 eV降低到化合物1b的-3.68 eV和化合物1c的-3.66 eV，并伴随着吸收光谱和荧光光谱的显著红移，最大吸收和发射峰从化合物1a的413和432 nm红移到化合物1b的460和543 nm以及化合物1c的479和552 nm。

By use of titration analysis, the thesis investigated various factors such as isocyanate, PE molecular weight, reacting substance molecular ratio, reacting temperature and time etc. influencing upon prepolymerization step. It was found that 2, 4-tolulene diisocyanate and 4, 4'diphenylmethane diisocyanate is more rapidly reacted with PE600 than HDI. With PE molecular weight increasing, the reacting temperature or time should be raised or extended relevantly. Thus PE2000+2HDI pre-polymerization should be better carried out under some catalyst, for example, Triethylene diamine , Dibutyltin dilaurate and Tin octoate were used.

首先采用滴定分析方法对WRPU预聚反应的影响因素进行了研究：芳香族二异氰酸酯TDI、MDI比脂肪族二异氰酸酯HDI反应活性高，其中TDI在反应初始阶段的反应速率比MDI快，不过随着反应的进行，MDI比TDI反应速率加快，这主要是因为TDI分子中的两个-NCO反应活性差异大所致；二元醇分子量越大，反应速度越慢；聚醚二元醇比聚酯二元醇的反应速度快；当分子量超过2000的二元醇与HDI进行预聚反应时，需借助适当的催化剂来加快反应速度，从而使预聚反应能够顺利进行，分别选择DABCO、TOA和DBDTL三种催化剂进行催化反应，发现不同的催化剂，其催化效果相差较大。

The objections of this article were as follows: to study the actions of Resuscitable nasal drops against sleep deprivation; to explore the effecting mechanism of the new drug ;to evaluate the application of automatic sleep deprivation recorder in rats, in order to make it applied widely.
