Seismic PKP arrivals are sensitive to P velocity structure in the lowermost mantle.
PKP震相包含了下地幔底部P波速度结构的重要信息。
Well, at point P, the velocity vector QP is perpendicular to the line QP, 1 so the sine of that angle is one.
点P，速度向量,垂直于直线，所以该角的正弦值为。
And the velocity of slow compressional-wave (P-wave) is in direct proportion to the porosity and the density of fluid.
而慢纵波的速度则和孔隙度和流体的密度成正比。
