| 对不同厚度液体进行光强测量,深入探索空化气泡的运动,研究发光机理很有意义。用超声激励法在磷酸液体中实现多泡声致发光,研究不同共振频率下发光的特点。利用光电倍增管多次测量发光强度相互比较,结果是在液体厚度10 cm、驱动频率f=21.061kHz和f=20.316kHz时,周期性较好为50μs,液体通过漩涡集中气泡可以使更多气泡发光；在液体厚度3 mm、驱动频率f=17.91kHz和f=19kHz时,周期性很好为25μs；且光信号都较强。结论是磷酸中声致发光强度、周期与液体厚度、驱动频率密切相关。本文以磷酸液多泡声致发光实验研究为基础,从内部和外部原理来出发,详细介绍了光电倍增管在多泡声致发光光强测量中的实用,为今后研究者提供了一些经验。根据实验过程中遇到的一些实际问题提出了建议和改善意见。 |

| It is of great importance to measure light intensity in different thickness of liquid, explore movement of cavitation bubble and study luminous mechanism. By using Ultrasonic irradiation method, sound luminescence in the phosphoric acid phosphoric liquid has been achieved and its luminescence feature in different resonant frequency was studied. Using photomultiplier to measure light intensity in the phosphoric acid phosphoric liquid, it was found that stronger light intensity and good cyclicity can be achieved with liquid thickness of 10cm, driver frequency between f = 21.061 kHz and f = 20.316 kHz. When thickness of liquid was 3 mm and its frequency was between f = 17.91 kHz and f = 19 kHz. Its cyclicity was 25 μs and optical signal was stronger. So conclusion is that luminescence intensity and cyclicality in phosphoric acid is closely related to its liquid’s thickness and driving frequency. Based on phosphate liquid much bubble luminescence, the application of photomultiplier in measurement of light intensity is described in detail and suggestions on its improvement are discussed in this paper. |
