中文摘要:
      文章从试验上分析了超声对清洗剂溶液液面上压力和表面张力的影响。超声效应与纯热效应明显不同,即使剔除热效应的影响,纯超声效应对密闭容器中流体液面上气体压力的影响也是很明显的,而且当超声作用足够长的时间后,压力随时间的变化在某一压力值附近波动。超声对溶液表面张力的影响与溶液的溶质及其浓度有关,在一定的浓度范围内,超声能引起溶液表面张力降低,并在某一浓度(PM)上达到极小。
英文摘要:
      The ultrasonic effect on the surface tension of several kinds of detergent solution and the gas pressure above the sample liquid were anslyzed by test.The ultrasonic effect differs clearly from the heat effect.It is very clear that the ultrasound influences the gas pressure above the sample liquid in an airtight vessel even if the heat effect is rejected.In addition,when the ultrasound irradiation is held for enough time,the gas pressure rises or falls around a certain value with time.The ultrasonic effect on the surface tension is concerned with the solute and the concentration of the sample solutions.Within the certain concentration range,the ultrasound irradiation lowers the surface tension of the sample liquid and that will get the minimum value at a certain concentration(PM).
