In the oil-generation window fluoranthene/pyrene reduced with the rising of maturity, and so did benzofluoranthene /benzopyrene in the mature to highly mature stages.

在成熟—高成熟阶段，苯并萤蒽/苯并芘比值也基本随熟度增加而降低。

Compared with the corresponding environmental guideline values, PAHs components, such as naphthalene, phenanthrene, fluorene, anthracene, Benzo fluoranthene and benzo fluoranthene, may have/had different level of biological effects.

此外，参照有关环境质量标准，发现悬浮颗粒物中萘、菲、芴、蒽／苯并荧蒽和苯并荧葱等化合物已经产生不同程度的生物影响效应。

Anti-benzimidazole eggs of Haemonchus contortus were collected with saturated salt and sugar solutions,respectively. The egg hatch test in vitro of H.contortus was carried out in different concentrations of benzimidazole solutions for different preservative periods.

One class is CAAX-mimetic compounds with an imidazolyl residue on one end and a carboxylic group on the other connected by benzodiazepine scaffold at different positions.

连有咪唑基的苯并二氮杂草化合物，以苯并二氮杂草-2-酮为分子骨架，7位连接含有咪唑基的侧链，1位或3位连接含羧基或酯基的侧链。此类化合物模拟了CAAX配体。

Result shows that the sulfur compounds in the diesel can react with iodomethane easily at room temperature, the most of sulfur compound derived into methylsulfonium salts; the homologue of benzothiophene get the higher conversion ratio and react selectivity than the homologue of dibenzothiophene. It is found that primarily sterically hindered alkylated DBT, for example, 4-or 4-, 6-DBT, is recalcitrant to be methylated.

结果表明：柴油中硫化物在室温条件下容易与碘甲烷发生甲基化反应，大部分硫化物转化为锍盐，总转化率超过80%，苯并噻吩类比二苯并噻吩类更易发生甲基衍生化反应，转化率也相应较高。

In this paper, we designed and synthesized a molecule of compound 1, 2-(benzooxazol-2-yl)-5-4-(3-(benzothiazol-2-yl) phenylamino-6--1,3,5-triazin-2-ylaminophenol, which can only assembled into an organogel upon a short irradiation with ultrasound in toluene-methanol mixed solvent. DSC, XRD and IR were used to detect the properties and mechanisms of the organogel.

本论文中，我们设计合成了一个有机小分子化合物1，4-氨基（2-羟基苯基）苯并噁唑3-氨基苯基苯并噻唑二辛基胺缩三聚氯嗪，研究发现，在甲苯/甲醇=1：2的混合溶剂中，只有利用超声才能使之形成凝胶，加热冷却的方法不能形成凝胶，而形成针状结晶。

These compounds exhibited higher activity than diphenylethers and they are one of the most hot fields in pesticidal chemistry.
