在薄球壳压电换能器等效电路的基础上，对它的声源函数和机电瞬态特性进行了数值模拟和分析。由于薄球壳压电技能器可以均匀地向四周辐射声波，因此，它能够等效为声波测井和地震勘探研究中所采用的无方向点源。文中所得到的结论为声波测井网络理论的物理模型建立奠定了基础。
Based on the equivalent circuit of the thin-shell piezoelectric transducer, the sound source function and electromechanical transient performance of the thin-shell piezoelectric transformer are numerically simulated and analyzed. Since the thin spherical shell piezoelectric transducer radiates sound waves evenly around it, it can be equivalent to a non-directional point source used in sonic logging and seismic exploration. The conclusion obtained in this paper lays the foundation for the establishment of physical model of sonic logging network theory.
