| 摘 要： | 从几何光学的角度出发,针对气泡直径与光束直径之间的大小关系,分两种情况,推得了单个气泡的散射光强变化情况,以及气泡速度与散射光强之间的关系.得出散射光强的变化频率与气泡半径和速度存在一定的关系,光束的直径与气泡直径的大小关系决定光强变化的强弱.在此理论基础上,模拟了光强的变化,并与实验所得曲线相比较,验证了实际与理论的相符性.同时用短曝光、连续拍摄的数码相机对气泡进行拍摄,进一步验证了理论推导的正确性. |

| Abstract: | In the point of geometrical optics, based on the size of bubble and the beam of light, the variety of single bubble’s scattering light was speculated at two conditions, the relation between the speed of bubble and scattering light intensity was also speculated. The conclusion was that variation frequency of scatter light is connected with bubbles radii and velocity. The relation between the diameter of the light beam and the diameter of bubble decides the change degree of light intensity. Based on the theory analysis, the scattering light intensity was simulated and compared with experimental curve. The validity of the theory was validated with short exposal and continue shot digital camera. |
