本研究的目的是评估不同分裂测量技术在日本下方俯冲的特别复杂的构造环境中的性能。我们使用来自宽带日本 F-net 阵列的数据，并考虑 Silver 和 Chan (1991)、Levin 等人的方法。 （1999）和雪佛兰（2000）。我们发现，结果总体上一致，尽管如果站下方的各向异性比分裂研究中经常假设的简单单层各向异性模型更复杂，则会出现差异。多通道和单记录方法的结合可以作为识别复杂性和表征台站下方上地幔各向异性的强大工具。
The goal of this study was to evaluate the performance of different splitting measurement techniques in the particularly complicated tectonic setting of subduction beneath Japan. We use data from the broadband Japanese F-net array and consider the methods of Silver and Chan (1991), Levin et al. (1999), and Chevrot (2000). We find that the results generally agree well, although discrepancies arise if the anisotropy beneath the station is more complex than the simple single-layer an- isotropic model often assumed in splitting studies. A combination of multichannel and single-record methods may serve as a powerful tool for recognizing complexities and for characterizing upper-mantle anisotropy beneath a station.
