and a lot of ultrasonic cavitation is an important mechanism of ultrasound.
而超声空化是很多超声应用的重要机理。
this paper studies the sonoflourescence image reflected by different objects, and analyses the propagation feather in reflecting of ultrasonic cavitation field.
本文研究了不同物体反射时的声致荧光影像,由此进一步分析了超声空化场的反射传输特点。
the experiments shows that ultrasonic cavitation decreases the degree of degeneracy polarization of the samples. it may be, it is the reason that ultrasonic cavitation expands molecule axis.
实验表明,超声空化缩小了所测样品的喇曼光谱退偏度,分析认为这是超声空化拉长了分子轴所致。
furthermore, this paper presents a new method which combines sonoluminescence image, hydrophone, chnn, b-p neural network to study ultrasonic cavitation field.
we measured the temperature rising rate in jetting ultrasonic cavitation water, gave a welding test of plastics in the water and had a discussion on the ultrasonic welding method.
测定了喷射超声空化水的温度变化,试验了塑料的水下超声焊接,并讨论了这种焊接方法。
in the fifth chapter, we record the sl image resulted from ultrasonic cavitation and studied the relationship between the sl intensity and ultrasonic intensity.
