this clearly indicates that uniqueness is reached provided that the irrotational and equivoluminal wave velocities, and are real and nonzero. 這就清楚地表明,如果無旋波速度和等體積波速度是不等于零的實(shí)量,則唯一性是成立的。
High precision velocity analysis of converted wave 高精度轉(zhuǎn)換波速度分析
Body wave velocities 體波速度
The second wave , the one that can cause damage , moves at a slower four kilometers per second 第二種波速度較慢但可能造成危害,以每秒4千米的速度傳播。

Rayleigh wave method is applied in projects more and more , however just determines the nature of soil . however the amount of shear strength , the degree of consolidation are needed in projects 這樣,影響了該方法的應(yīng)用,因此,有必要從理論上尋找瑞利波速度跟強(qiáng)度或者固結(jié)度的關(guān)系式。
1 , travel times of 91138 pn arrivals recorded from china and adjacent regional earthquakes are inverted in a tomographic study to map the lateral variations and anisotropy of pn velocity of the uppermost mantle 1 、用91138條pn射線的走時反演出中國大陸上地幔頂部的p波速度橫向變化和各向異性分布。
