混合酸 meaning in English

mixed acid

New synthesis method of n - heptyl - p - hydroxybenzoate by the complex acid catalysis
混合酸催化合成对羟基苯甲酸庚酯的新方法
The ratio of tetraethyloxysilane ( teos ) : ethanol : distilled water is 1 : 3 : 4 . n - n " dimethyl formamide ( dmf ) was used as solvent and drying control chemical additive ( dcca ) in a proportion of 0 . 3 dmf / ethanol volume ratio . drops of hf / hc1 mixture acid was added to promote hydrolysis ( ph = 2 )
溶剂的选择对基质凝胶孔的形状基本没有影响，但对其孔径分布有较大影响:在hf / hci混合酸催化情况下， dmf溶剂的样品孔径最小， dmf /乙醇混合溶剂的其次，乙醇溶剂的样品孔径最大。
The amounts of salmonella were 1 . 3 x 108cfu / ml after 20 hours in co - culturing with bi . when four strains supernatants and acetic acid - lactic acid ( 3 : 2 ) of ph4 were added to broth media to culture salmonella , it was found that the inhibitory ability of acetic acid - lactic acid was the highest , then was that of ba , bl and bbr supernatants , and the inhibitory ability of bi supernatant was the lowest
将ph值接近4的四株菌的上清液和0 . 1m 、 ph4的乙酸-乳酸( 3 ： 2 )混合酸液以一定比例加入培养基中，培养沙门氏菌，发现酸液对沙门氏菌的抑制作用最强： ba 、 bl和bbr上清液的抑制强度相近，但不及酸液； bi上清液的抑制作用最差。
