| 摘 要： | 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。

| Abstract: | On the basis of the equivalent circuit for a thin spherical shell piezoelectrictransducer, the numerical simulation and analysis of its source function and electrical-mechanical property is performed in this paper. Because the thin spherical shell transducer radiates sonic waves evenly in all directions, it can be equivalent to an ommidirectional point source. The results obtained in this paper set up the basis of the sonic logging network theory. |
