The recoveries for 2,3-BD and acetoin were 91%and 92%,respectively.Aqueous two-phase extraction of 2,3-BD from real fermentation broth,the removal ratio of cells was above 99%,and the soluble proteins were about 85%in the top phase,which resulted in easy recovery of 2,3-BD from the top phase by vaporization because a viscous slurry was not formed by glucose,cells and soluble proteins at high temperature as in traditional separation methods.In addition,the cells recovered from the fermentation broth could be used as inoculum for further fermentation.

结果表明，目标产物2，3-丁二醇和乙偶姻主要富集在上相中，而葡萄糖主要富集在下相中；当异丙醇和硫酸铵的质量浓度分别是34%和20%时，2，3-丁二醇和乙偶姻的分配系数分别为8.29和8.98，回收率分别达到91%和92%；采用该条件对发酵液直接进行萃取，细胞的去除率在99%以上，可溶性蛋白去除率可达85%。

As mentioned above, this dissertation can be divided into two parts. One is devoted to study the high resolution ro-vibrational spectra of some asymmetry top molecules, such as D〓O and DOCl. Another is about studying anharmonic force field and vibrational intensities of some symmetry top molecules by quantum chemistry method, such as SiHCl〓 and AsH〓.

因此本论文的工作以此为脉络分为两个部分，第一部分以D〓O和DOCl分子为体系，研究非对称陀螺分子的高分辨振转光谱；第二部分以对称陀螺SiHCl〓和AsH〓分子为体系，用量子化学计算的方法研究了小分子的非谐性力场和振动光谱强度。

Although love was the top choice overall and the number one choice for women, antidisestablishmentarianism was the top choice for men and the ninth most favourite word on the list.

&爱&一词名列最受喜爱词语排行榜之首，同时也是女性的最爱，但&主张教会分离者&一词则为男性的首选，并在总排行榜上名列第九。

Through computer simulation of azeotropy rectification dehydration tower with benzene as entrainer, the optimal technical parameters were obtained as follows:①the output quantity of top tower was 69 kg／h, return benzene phasor as 58 kg／h and reflux ratio as 3, alcohol concentration in charge the higher the better, however, its maximum value influenced by water content at azeotropy point;②sensitivity analysis results indicated that the sensitivity of output quantity of top tower was the highest, alcohol concentration in charge the second and return benzene phasor and reflux ratio the lowest.

对以苯作为夹带剂的共沸精馏脱水塔进行了计算机模拟，得到了最佳工艺参数：①塔顶采出量为69 kg／h，返回苯相量为58 kg／h，回流比为3，进料乙醇浓度越高越好，但其最大值受共沸点水含量的影响。②敏感性分析的结果为塔顶采出量的灵敏度最大，进料乙醇浓度次之，而返回苯相量和回流比较小。
