我们使用直接求解法 (DSM) 和最精确的数值算子来计算横观各向同性 (TI)、球对称介质（最高 2 Hz）的完整（包括体波和面波）三分量合成地震图。我们提供了深层（600 公里）和浅层（5 公里）源的计算示例。这种合成物应该可用于地球结构的正向和逆向研究。为了准确有效地进行这些计算，必须仔细、系统地选择垂直网格间距、最大角阶和截止深度。
We use the direct solution method (DSM) with optimally accurate numerical operators to calculate complete (including both body and surface waves) three-component synthetic seismograms for transversely isotropic (TI), spherically symmetric media, up to 2 Hz. We present examples of calculations for both deep (600 km) and shallow (5 km) sources. Such synthetics should be useful in forward and inverse studies of earth structure. In order to make these calculations accurately and efficiently the vertical grid spacing, maximum angular order, and cut-off depth must be carefully and systematically chosen.
