It was, thus, concluded that the influence of ultrasonic waves on the production of alcohol in presence of NaCl was inconspicuous as compared with the effects of other salts. It was evident from the fact that even the optimum yield of alcohol could not exceed the control. However, the influence of ultrasonic waves alone and its influence in presence of KH2PO4 could enhance the amount of alcohol over the control by 45.6% and 26.1%, respectively. The best result obtained amongst these treatments was found with the effect of sonics in presence of NH4Cl, in which the amount of alcohol produced was greater than that of the control by 51.3%.
因此得出结论，与其他盐类的作用相比，超声波在氯化钠存在的情况下对酒精产量的影响并不显著。从即使酒精的最佳产量也无法超过对照这一事实可以明显看出。然而，单独的超声波作用及其在磷酸二氢钾存在时的作用，分别可使酒精产量比对照提高45.6%和26.1%。在这些处理中，发现氯化铵存在时超声波作用的效果最佳，所产生的酒精量比对照多51.3%。
