Meanwhile, the most difficult task for simulation and optimization of heterogeneous distillations is to determine whether the liquid phase is stable in column stages or packing sections, which is also one of the focuses of this dissertation.

对三相共沸精馏过程而言，一个汽相和两个液相(来源：ABC论文68网www.abclunwen.com)形成汽液液三相共存现象，第二个液相会或多或少地改变精馏过程的流体力学特性并最终影响过程的传质分离效率。

The results of the study demonstrated that the pathogens of GNTVE are consisted of GPV and FAV-1, and GEF is the optimal laboratory host for the of pathogens. The the developed duplex PCR-based protocol is useful for the rapid diagnosis of GNTVE. The developed IOE vaccine and immune serum can provided very good passive immunity for gosling against GNTVE.

研究的结果表明，GNTVE是一种临床综合征，其病原包括GPV和FAV-1两种病毒；GEF是用于病原分离的优良宿主系统；建立的二重PCR方法可用于该病征的快速诊断；研制的灭活油乳剂苗和高免血清能很好地对该病征进行预防。

Vandierendonck,A.,'The contribution of working memory resources in the verification of simple mental srithmetic sums',Psychological Research,1999,62,72-77.% q! Y! l*~# y: ^ [5] Miyake,A.,Friedman,N.P.,Emerson,M.J.,Witaki,A.H.

由于这两种任务只对中央执行系统产生干扰，对其他两个子系统不产生影响，因而能有效地分离工作记忆各子系统的功能，使研究更有效。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.
