The above analysis shows that both ultrapure volatile coal , the reduction coal or organic functional group content has proven to reduce the chemical treatment makes coal organic structure changes 以上分析可以看出，无论是超纯煤挥发分的降低，还是煤粉中有机官能团含量的降低都证明化学处理使得煤粉有机结构发生了变化。
Characterization of fresh bc and asphaltenes show that fresh bc structurally rigid and physically condensed . and different to graphite , bc contains a little aliphatic groups and oxygen - containing groups 但现代碳黑又不同于石墨，它还具有一些含氧官能团、脂珠江三角洲地区土壤和表层沉积有机质的非均质性研究肪碳等结构。
Compared with other template , especially organic templates , the types of functional groups , the size , the composition , and even cross - linking density of microgels are easily controlled 与其他有机模板相比较，微凝胶的组成成分，特别是其中所含官能团的类型、微凝胶大小、交联密度等都可以通过选择单体、调节反应条件等加以控制。
Modification method of organo - siloxane modified acrylate latexes main includes physical blend and chemical copolymerization , the methods of organo - siloxane modified acrylate latex were reviewed 摘要多官能团有机硅功能单体对丙烯酸酯乳液改性研究主要包括物理共混和化学共聚法，本文对有机硅改性丙烯酸酯乳液的研究方法进行了系统的综述。
The surface chemistry of anion - exchange fiber synthesized from natural cotton was also studied , in order to further understand the effect of surface functional groups of ion - exchange fibers on their adsorptive and exchange properties 还对天然棉纤维基离于交换纤维的表面化学进行了研究，以探讨离子交换纤维的表面官能团对吸附交换性能的影响。
It is to be understood that when in this specification we speak of a dialkyl carbonate and similarly of a dialkyl phenylmalnate , that term does not imply that the two alkyl groups are necessarily the same 有一点要理解：在说明中我们提到二烷基碳酸酯，相似的我们还提到了二烷基苯基丙二酸酯，这两个术语并不是暗示这两个烷基官能团必须是一样的。
The organic chemistry experiment lesson request students to grasp basic operation and technical ability of organic chemistry , the property and the typical organic reaction of the organic functions groups ; to acquaint with the usage of the instruments in common use 有机化学实验课要求掌握有机化学基本操作技能，官能团的性质及典型有机化学反应；熟悉常规仪器的使用。
This lesson mainly introduces the structure of organic compounds , name , the physics and the chemistry property , the organic functions groups converts mutually and law ; characteristic of stereoscopic chemistry ; the typical reaction process 这门课主要介绍有关有机化合物的结构、命名、物理及化学性质，官能团化合物之间的相互转换及其规律；立体化学特征；典型有机反应的反应历程。
At last , the structure - to - property is researched , we design a series of trans - stilbene derivatives with different arrangements of the substitutions and study their two - photon absorption properties by using the response theory method at hf level 最后，本文选取了一系列不同官能团取代的具有不同对称性的二苯乙烯系列衍生物，对其双光子吸收截面与分子结构之间的关系进行了研究。
On one hand , these organic function groups decorate the surface of nanoparticles by combining with the surface dangling bonds . and most important , they may act partially as the donor of d - a pairs in the sa luminescence by providing electrons 讨论了吸附在纳米颗粒表面的一oh ，一ch = ;和一coo等有机官能团的作用，明确提出了这些官能团中的一部分可能充当了自激活发光施主一受主对中施主的观点
