The results showed that the mulberry fruit surface carried large numbers of yeast but little other mixed fungi; ethanol fermentation reached the peak value in 48h'; the acetification bed breeding took 9~10 d before vinegar production, but the vinegar fermentation cycle was only about 24h during production.

结果表明，桑椹果实表面携带有大量的酵母菌而几乎不带其他杂菌，酒精发酵醪除含有大量的酵母菌之外未发现有其他杂菌，酒精度在发酵48h时达到高峰；桑椹醋生产前的醋酸菌床培育需要9~10d，投入生产后酷酸发酵周期仅需要24h；桑椹醋总黄酮含量高达6.68mg/mL，对DPPH的清除作用远大于山西陈醋、镇江香醋和山楂果醋，具有良好的抗氧化作用；利用桑椹醋自身色素颜色变化可判断酸度测定时酸碱滴定终点。

Product has mainly engaged in alcohol-benzene toluene xylene butyl acetate ester, such as acetone acetophenone ring.

主要经营产品有甲苯二甲苯醇苯醋酸丁酯乙酯丙酮环乙酮等。

In the same treatment concentration and time, effect of acetum on 7 pesticide residues in cabbages surfaces were high than salt solution. The tap water treatment was the worst. There are no significant effects on pesticide residues in cabbage that refrigeration 12-48 h.

结果表明：在相同浓度和处理时间下，醋酸溶液对甘蓝叶片表面7种农药的去除效果要好于盐溶液，自来水对7种农药的去除效果在3种处理溶液中最差。

Methods To create the rat model of gastric ulcer cauterized by acetum. The rat we treated by drinking alkalescence ion water which pH value we difference and to observe the state of rat gastric ulcer haling.

采用醋酸烧灼型大鼠胃溃疡模型，对整水器处理后生产的不同pH值的碱性离子水对胃溃疡愈合的作用进行研究。

The effects of the mass ratio of polyvinyl alcohol and chitosan,the volume of acetum,the concentration of crosslinker on swelling ration are studied and optimized using orthogonal experimental method.

凝胶溶胀度随着聚乙烯醇与壳聚糖质量比、交联剂戊二醛浓度的增大而减小，随着溶剂醋酸溶液体积增加而增大

The effect of different calcium chloride concentration, reaction time and neutralized acid on yield of tagatose was investigated by single factor tests. Results showed that the condition, such as calcium chloride (0.01～0.03 mol/L), reaction time(20～40 min), acetum, carbon dioxide, phosphate acid to synthesize tagatose was suitable.

通过单因素实验，确定了以D-半乳糖为原料进行化学法合成D-塔格糖的工艺条件为：CaCl2的添加量在0.01～0.03 mol/L，反应时间在20～40 min，并用醋酸、CO2、磷酸中和时D-塔格糖产率较高。

Through the orthogonal experiment, the optimum condition for tagatose synthesization was determined to be 0.02 mol/L calcium chloride, 30 min, acetum neutralization.

通过正交设计实验优化反应条件，最终确定以0.02 mol/L的CaCl2为催化剂，反应时间30 min，用醋酸中和金属氢氧化物D-塔格糖复合物时，D-塔格糖的产率最高，可达到49.05%。

Removal techniques of pesticide residues in cabbage leaves surfaceRemoval efficacies of organophosphates, orgnaochlorine (p,p-DDT andγ-666), pyrethroids and fungicide chlorothalonil residues in cabbage leaves surface caused by different concentrations of salt solution, acetum, tap water, refrigeration and cooking were simulation studied in laboratory.

蔬菜叶片表面农药残留日常去除技术在实验室模拟了不同浓度的盐溶液、醋酸溶液，自来水，冷藏和烹饪对甘蓝叶片表面有机磷农药、有机氯农药(p，p-DDT、γ-666)、拟除虫菊酯农药、杀菌剂7种农药的去除效果。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
