作者们用试验证明:在次氯酸钠、次氯酸钙、来苏尔及乳酸四种化学药品中,乳酸对于殺滅空气中的病毒具有明显的效力;且为其他三种药物所不及。在实验室中,每立方米空间用2%乳酸溶液10毫升喷霧,经30分鐘后,即能完全殺滅空气中的甲型、乙型、次甲型流感病毒和流行性腮腺炎病毒。乳酸之此种作用不受室温变动的影响(在 The authors demonstrate with tests that lactic acid has significant efficacy against viruses in the air in sodium hypochlorite, calcium hypochlorite, lysh and lactic acid and is out of reach of the other three drugs. In the laboratory, spray 10 ml of 2% lactic acid solution per cubic meter of space for 30 minutes to completely kill the A, B, A and Mumps viruses in the air. This effect of lactic acid is not affected by changes in room temperature (in
