The acidimetric supernatant was considered as the system blank to compensate the influence of particle dissolution and complex reactions between soluble components on estimation of proton consumption. 将酸量滴定上清液作为体系空白以补偿固体颗粒溶解和组份间络合反应对定量估算质子消耗的影响。
β-lactamase determination were performed by Iodometric method and Acidimetric method. 用碘试管法和酸试管法测定β-内酰胺酶,用K-B法进行药敏试验。
