圆形探头超声声场仿真，可通过改变换能器尺寸和声场设计来计算声场的聚焦点变化，也可以改变换能器聚焦的曲率半径大小-acoustic field simulation

超声波探头聚焦声场仿真和水浸探头以及相控阵探头，可以通过设置探头频率和探头直径，模拟超声发射声场，实用性强。(The simulation of focused acoustic field of ultrasonic probe can simulate the acoustic field of ultrasonic emission by setting probe frequency and probe diameter, which is practical.)
