摘　　要：使用平面、斜面、圆锥和无底座几种类型的小球反射体,对平面超声水浸探头的远近场分界点和声束宽度参数进行了测量,分析了当下主流测试标准中小球反射法测量时底座设定的发展趋势和合理性。The base as large volume support, its shape have great influence on the measurement.In this paper, far and near field boundary points and beam width parameters of a planar ultrasonic immersion probe are measured,by using plane base 、inclined base、conical base and no base. The development trend and rationality of regulation in the current mainstream testing standards are analyzed.
