摘　　要：利用平面激光诱导荧光系统(Plane Laser Induced Fluorescence’简称PLIF)测量水力学物理模型中竖直截面温度场,研究温排水竖直平面形态。温排水竖直截面经历从肾形到马蹄形结构,再到出现分叉现象,最后马蹄形结构消失的过程。PLIF系统在水力学物理模型试验研究中的应用前景较广,在众多科研项目中发挥了重要作用,提高了水力学模型试验的研究水平。PLIF(Plane Laser Induced Fluorescence) is used to measure the temperature field of the vertical section of the hydraulic physical model, and the shape of the vertical plane of the warm drainage is studied.The vertical section of the warm drainage experienced a process from kidney shaped to horseshoe shaped structure, then to bifurcation, and finally the horseshoe shaped structure disappeared. PLIF system have a wide application prospect in the research of hydraulic physical model test.They can play an important role in many scientific research projects and improve the research level of hydraulic model test.
