加氢异构化方法包括将含烃进料（39）引入分馏塔（40）中，其中，它被分离成350°F－的轻馏分和350°F＋的重馏分。

The essential oil was prepared from the peel by solution extraction, and separated into fractions of hydrocarbon and oxygenated compounds through a silicagel column. As the oxygenated fraction had the characteristic aroma of the peel oil, odor quality of the fraction was estimated on the basis of a odor unit value. Twenty five compounds such as geranial, neral, linalool and aliphatic aldehydes were selected as the components contributed to the aroma of the peel oil.

用溶剂萃取法提取白柠檬果皮的精油，并用硅胶柱将精油分成碳氢化合物和含氧化合物两大部分，由于含氧化合物部分具有果皮油的特征香气，利用各成分的香气值对该部分进行了评价，明确了香叶醛、橙花醛、沉香醇以及一些脂肪族醛等25种成分对白柠檬果皮油香气起着重要作用。

If the numerator is greater, it is called an improper fraction and can also be written as a mixed number-a whole-number quotient with a proper-fraction remainder.

真分数的分子比分母小；如果分子比分母大，称为假分数，并且可以以带分数的形式表示，即一个整数加上一个真分数。

In the second part of this research, the effect of the addition of ethanol on the micellization of C14TAB was studied also by ITC at temperatures of 15-40℃. The results show that with increasing ethanol concentration the cmc values first reach a minimum at an intermediate ethanol mole fraction xmin and then increase with increasing ethanol mole fraction.

本研究中第二部份为利用恒温滴定热卡计，研究温度范围15℃40℃之C14TAB + ethanol效应，由实验结果发现cmc值会先随著乙醇浓度增加达到最低值，此时的乙醇莫耳分率为xmin，然后cmc值再随著乙醇浓度增加而增加。

Deformation greatly promoted carbonitride isothermal precipitation and made C-curve shift leftwards. The position and shape of C-curve depended on the content of Nb and N to a great extent, C-curve shifted leftwards a little when N content increased and its nose temperature was raised with Nb content increased. 3 when cooling rate increased, start temperature and finish temperature of continuous cooling precipitation decreased, full precipitation became difficult to take place, the volume fraction of carbonitride precipitation decreased, molar fraction of Nb and C dissolved in austenite increased, and the precipitation grain was further refined. Deformation shorten precipitation start time during continuous cooling, raised precipitation start temperature, accelerated precipitation kinetics of carbonitrides.

计算表明：1在Fe—Nb—C系统中，随着温度的降低，析出相的平衡体积分数增加，溶解在奥氏体中的Nb、C的摩尔分数降低，析出相中C和Nb的原子分数的比值v增加；2变形大大促进了碳氮化物的等温析出，使C曲线左移，Nb和N的含量与C曲线的位置和形状有一定的关系，N含量的增加，使C曲线略有左移，而Nb的含量的增加使得C曲线的鼻子区上移；3随着冷却速率的增大，连续冷却析出的开始温度和结束温度均有所降低，并且析出变得越来越不充分，析出相体积分数明显减小，溶解在奥氏体中Nb和C的摩尔分数增大，析出相粒子被明显细化，变形大大缩短了CCP过程碳氮化物析出的开始时间，提高了析出的开始温度，促进了析出动力学。

The results indicate that lgG'-,lgG-lgw relation-ship curves look as straight lines on the double logarithmic scale at lower mas fraction of fumed silica.In the higher angular frequency region,therer is a slight downward discrepancy for the curves from the straight line.With the increase of the fumed silica mass fraction the lines are upward translation,but the slopes decrease.
