摘　　要：对液体中热晕现象从新的角度，即矩阵光学的方法进行了处理，以热透镜为模型，建立了热晕效应的等效焦距形成发展过程的数学表达式。同时进行了部分实验以验证理论结果。成功地观察到了热晕形成发展的全部动态过程，得到了与理论计算基本一致的实验数据。在实验中，同时观测到了一些周期性的跳动现象，给出了定性的物理解释。This paper gives analysis to the thermal-blooming in liquid from a new respect of matrix optics,and set up the expression function of focal length of the thermal-blooming developing and formingprocess.Some experiments are carried our to identify the results of theory.The whole dynamic process ofthermal blooming developing is succussfully abserved and the experimental data consisting with the theoretical computation are got.In the experiments,a periodical beating phenomenon is also observed and the qualitative anslysis is given.
