percolation time meaning in Chinese
渗滤时间；渗透时间
Examples
- In contrast , the much shorter percolation time of espresso allows less acid and only 60 to 70 percent of the caffeine to dissolve into the brew
反之，制作浓缩咖啡时，滤滴的时间短得多，也就只有较少的酸及60 ~ 70 %的咖啡因进入滤液。 - The best condition for extracting polysaccharide from porphyridium cruentum were as follow : alcohol concentration was 50 % , alcohol volume was 1 - fold time , percolation time was 0 . 5h , the volume ratio of glycoprotein solution to sevag reagent was 2 : 1 , time was 45min and sevag reagent was 4 : 1 between chloroform and butanol . the result also indicate that sodium acetate anhydrous and nh4cl were the best carbonic and nitrogen source for polysa
血色紫球藻的最优提取工艺为乙醇浓度50 % ，乙醇用量为1倍体积，醇沉时间为0 . 5小时;氯仿与正丁醇的比例4 : 1 ，样液与sevag试剂的比例2 : 1 ，作用时间为45min ;五种碳源的影响差异不显著，氮源的影响差异显著，其中添加无水乙酸钠和nh4ci的培养基多糖产率最高，分别为33 . 784mg / l和40 . 997mg / l 。 - The polysaccharide production were 37 . 296mg / l and 12 . 961mg / l . the best conditions for extracting polysaccharide from porphyridium purpureum were as follow : alcohol concentration was 75 % , alcohol volume was 2 - fold time , percolation time was 1h , the volume ratio of glycoprotein solution to sevag reagent was 1 : 2 , time was 45min and sevag reagent was 3 : 1 between chloroform and butanol . the result also indicate that nahco3 and nh4cl were the best carbonic and nitrogen sources for polysaccharide respectively
淡色紫球藻的最优提取工艺为乙醇浓度75 ，乙醇用量为2倍体积，醇沉时间为1小时；氯仿与正丁醇的比例3 ： 1 ，样液与sevag试剂的比例1 ： 2 ，作用时间为45min ：由方差分析可得五种碳源和五种氮源对胞外多糖的影响不显著，添加碳酸氢钠和摘要nhoci的多糖产率最高，分别为41 - Deproteinized from crude polysaccharide by adopting sevag method . through orthogonal test , we found that the best constitution for extracting polysaccharide from porphyridium aerugineum 755 were as follow : alcohol concentration was 50 % , alcohol volume was 3 - fold time , percolation time was 1 . 5h , the volume ratio of glycoprotein solution to sevag reagent was 1 : 2 , time was 15min and sevag reagent was 4 : 1 between chloroform and butanol . the result also indicate that lactose and ( nh4 ) 2so4 were the best carbonic and nitrogen sources for polysaccharide respectively
研究结果表明，三种紫球藻的最佳提取工艺各不相同，铜绿紫球藻的最优提取工艺为乙醇浓度50 ，乙醇用量为3倍体积，醇沉时间为1 . 5小时；氯仿与正丁醇的比例4 ： 1 ，样液与sevag试剂的比例1 ： 2 ，作用时间为15min ；由方差分析可得五种碳源和五种氮源对胞外多糖的影响不显著，其中添加乳糖和( nh _ 4 ) _ 2so _ 4的培养基多糖产率最高，分别为37 . 296mg l和12 . 961mg l 。
