- The optimized solution of the regression equation was that: Z1 (ethanol concentration) 75%, the ratio of Z2 (ethanol volume) to Volume of PPP 15:1 (V:V), the N/P was 14.69. 将此数学模型进行规划求解知乙醇钙纯化法的最优工艺参数Z1乙醇浓度为75%25，乙醇体积与提取前PPP体积比Z2为15:1(V:V)；
- Adopt the experiment byorthogonal,review the ethanol magnitude、ethanol concentration、extractiontime,appraise with the content of emodin and polydatin,establis. 采用正交试验,考察加醇量、醇提时间、醇浓度3个影响因素,以总蒽醌、虎杖苷含量为综合评价指标,优选虎杖醇提最佳工艺条件。
- Effective because it has a much greater affinity for alcohol dehydrogenase than methanol. A blood ethanol concentration of 100 mg/dL (22 mmol/L) will almost completely block methanol metabolism (Jacobsen &McMartin, 1986). 甲醇中毒最好的办法就是用酒精中和，因为乙醇比甲醇更易与人体内的脱氧酶的结合，阻止甲醇对人体的毒害。
- Finally,take the high acid production of molasses as the carbon source,in different ethanol concentration,temperature,salinity and pH value conditions for acid qualitative tests and studies to determine Acetobacter As1.41 the best culture conditions. 最后以产酸量最高的糖蜜为碳源;在不同乙醇浓度、培养温度、矿化度和pH值条件下进行产酸定性试验及其研究;从而确定醋酸杆菌As1.;41最佳的培养条件。
