Objective To study the application effect of dyeing method on measuring cavitation effect of ultrasonic cleaning machine.Methods The experiment was divided into dyeing group and aluminum foil corrosion group.Methylene blue+coated paper and aluminum foil were used to test the cavitation effect of ultrasonic cleaning machine,and the two groups were repeated 10 times each.The operation time,total number of markers,average area of markers and standard deviation of marker distribution of the two groups were observed.Results The operation time(38±1.34)s,the average area of markers(7.48±1.42)pixels and the standard deviation(2.52±0.40)pixels of the distribution of markers in the dyeing group were lower than those in the aluminum foil corrosion group(215±6.11)s,(115.57±13.98)pixels and(3.48±0.71)pixels,respectively.The total number of marks in the dyeing group(1362±216.19)was higher than that in the aluminum foil corrosion group(91.10±18.76),and the differences were statistically significant(P<0.05).Conclusion The dyeing method has a short operation time and more comprehensive test record.
