芳香

The cokes are come from aromatics, colloids, asphaltene and Carbenes which are polycondensated and dehydrogenated. The processing of coking in the system are as follows: aromatics－→colloids－→asphaltene－→Carbenes－→cokes.(4) Coking can be avoided in the plasma reactor by feeding coal powder of 40～60 mesh (30%) and coal powder of less than 140 mesh (70%).

3结焦主要发生在等离子体反应较高温区，由煤中的芳香分、胶质、沥青质和碳青质缩聚脱氢形成；装置结焦形成的大体途径为：芳香分－→胶质－→沥青质－→碳青质－→焦质。

Accordingly, aromatic compounds can be divided into three groups and a delocalized π system itself is always destabilized, the dependence of aromatic ring current upon the CT was reveled, and ring rigidity has been defined as a new aromatic index.

据此，我们提出了芳环化合物新的分类准则，揭示了芳香环流起因的必要条件，定义环的刚度为芳香性一个新判据。发现，分子内基团间的局部作用同它们对分子整体性能的影响是完全相反的。

Such as,(1) Active Zincdust catalyzed the esterification reactions between benzoyl chloride and phenol or alcohol,which needed not solvent, warming and could fulfilled in a very short period (1-2min), andthe handling of the reaction mixtures was very simple. We believe it's the simplest and mosteconomic method for the synthesis of many aryl esters.

包括：(1)活性锌粉催化的酯化反应，在室温下即可反应，毋需溶剂，毋需加热，反应迅速(通常1—2分钟即可反应完全)，处理非常简便，相信目前是合成许多芳香酯最简便的方法，是一种值得加以推广的合成芳香酯的好方法。

Happy is the lover that hath inhaled the divine fragrance of his Best-Beloved from these words, laden with the perfume of a grace which no tongue can describe.

这话语充满无舌能形容的恩泽芳香，从中吸入至爱者之神圣芳香者必享福乐。

The o-aminobenzaldehyde ethylene acetals can be synthesized from corresponding o-nitrobenzaldehyde by reducing the nitro-group after the protection of carbonyl by ethylene. 2-Aminophenyl ketone ethylene ketal can also be prepared from 2-nitrophenyl ketones by this method.

邻氨基苯甲醛乙二醇缩醛可以由含不同取代基的邻硝基苯甲醛经羰基以乙二醇缩醛保护后还原硝基得到，邻氨基芳香酮乙二醇缩酮可以同样的方法由邻硝基芳香酮得到。

The photoreaction of diazo pyrazoles has been studied. And by this method, a kind of diaromatic ring has been obtained easily.

初步研究了重氮基吡唑光反应的特性，并利用此反应实现了在芳香环上直接引入另一芳香环。

Separation of racemic mixtures of thirty-eight secondary aromatic alcohols and arylethanediols with different substituting group was achieved with HPLC by using Chiralcel OD and Chiralcel LJ as chiral stationary phase and hexane/2-propanol mixtures of different ratios as eluents. The chromatographic parameters of these racemates on OD and OJ columns were examined.

在ChiralcelOD和ChiralcelOJ两支多糖类手性固定相上，以各种不同配比的正己烷-异丙醇为洗脱剂对38种带有不同取代基的芳香仲醇及芳香乙二醇类手性化合物的对映体进行拆分，考察了这些外消旋体在这两支手性柱上的色谱行为。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。

Climate histogram is the fall that collects place measure calm value, cent serves as cross axle for a few equal interval, the area that the frequency that the value appears according to place is accumulated and becomes will be determined inside each interval, discharge the graph that rise with post, also be called histogram.

气候直方图是将所收集的降水量测定值，分为几个相等的区间作为横轴，并将各区间内所测定值依所出现的次数累积而成的面积，用柱子排起来的图形，也叫做柱状图。
