In this paper, 238 Rayleigh wave path data are selected and processed by the matched-filtering frequency-time analysis technique and the grid dispersion inversion method to obtain the 3D S-wave velocity structure of China mainland and its adjacent sea regions. The results show that the velocity structure relates to geotectonic division, Bouguer gravity anomaly is basically controlled by the relief of Moho discontinuity, the buried depth of LVL in upper mantle concerns the surface heat flow deeply. In this paper, authors indicate the main characteristics of the velocity structure in tectonic active and stable regions. 相似文献

在实验教学中如何迅速、准确地检查学生的数据,又如何科学地批改学生的实验报告.在备课中如何分析各种实验数据,寻找实验规律,这都是重要而又十分繁重的工作.若要准确地批改学生的实验报告得需重新计算一遍,但计算一遍也得花费许多时间,在实验课教学之中如何迅速判断学生测得的数据正确与否常常出现凭着经验去判断.明知不科学,但常感到力不从心,在普物实验之中单、双变量的统计计算是经常运用的,但计算工作量较大.随着计算机的日益发展,为科学地分析实验数据提供了有力的 相似文献
