摘　　要：空化泡内气体对空化泡的产生、生长、崩溃及其发光机理研究有重要意义。基于刹管法,在去离子水与12,丙二醇中通过插不锈钢杆和插毛细管产生瞬态单一空气泡与氙气泡,测量了三种情况下气泡空化发光的强度,拍摄了1,2丙二醇中瞬态单氙气泡空化过程的高速照片。实验结果表明:插杆产生的空气泡的发光强度大于插毛细管产生的空气泡的发光强度,而插毛细管产生的空气泡与氙气泡的发光强度比较接近,瞬态单氙空化气泡接近于球形。分析了这些新现象产生的原因。The gas in the cavitation bubble has important significance for the producing,growing,collapsing,and lighting mechanism research of the bubble.Based on the tube-arrest method,the single transient air and xenon bubbles are produced by inserting a stainless steel rod and a capillary in deionized water and 1,2 propanediol respectively,meanwhile the luminous intensity of cavitation in three cases are measured,and high-speed photos of single transient xenon bubble in t1,2 propylene glycol are taken.Experimental results show that： the luminous intensity of the air bubble produced in rod case is greater than that in capillary,and the luminous intensities of air bubble and xenon bubble both in capillary luminous intensity are in the same order,the geometry of the single transient xenon bubble produced in the capillary is nearly spherical.The reasons of the new phenomena are analyzed.
