To protect the security and stable of film meter, should select some kinds right airproof liquate. 为保证隔膜表使用可靠性和安全性,应根据不同用途选择合适的密封液。
The method of acid decomposement and alkali liquate thaw is generally applied to decompose the core sample. 矿样的分解通常采用酸分解和碱性熔剂溶解的方法。
60 samples were selected from oil dregs of oil refining plant, screened by plate and liquate medium and menstruated lipase activity, starting strain was obtained by compared diameters of colony and hydrolyzed transparency circle on screening plate. 从含油的泥土中采集60份样品,通过平板检测法进行初筛,摇瓶复筛,并测定酶活。
