The influence factors such as ethanol concentration,extraction duration,extraction temperature were also studied.

In fermentation process, the ethanol concentration is one of the most important parameters, and directly influences the optimization and automatic control performance of fermentation system as well as the quality and yield of the output.

In the Animalcule fermentation process, ethanol concentration is one of the most important variables, and directly influences the optimization and automatic control performance of fermentation system as well as the quality and yield of the output.

Objective To observe the effect of Zuijiuling Ⅱ on the alcohol concentration in blood,the(activity) of alcohol dehydrogenase(ADH)in the liver and the concentration of neurotransmitter in the brain of mouse model with acute alcoholism.

Methods Selecting crush degree,alcohol concentration and extracting time as influential factors to make possitive cross test.

The Least Squares Support Vector Machines (LS- SVM) was applied to regress in order to get the value of the alcohol concentration.

The process for the synthesis of ethyl tert -butyl ether (ETBE) using tert -butyl alcohol (TBA) and low-grade ethanol (EtOH) by catalytic distillation was studied.
