| 1. | this clearly indicates that uniqueness is reached provided that the irrotational and equivoluminal wave velocities, and are real and nonzero.
这就清楚地表明，如果无旋波速度和等体积波速度是不等于零的实量，则唯一性是成立的。 |
| 2. | High precision velocity analysis of converted wave
高精度转换波速度分析 |
| 3. | Body wave velocities
体波速度 |
| 4. | The second wave , the one that can cause damage , moves at a slower four kilometers per second
第二种波速度较慢但可能造成危害，以每秒4千米的速度传播。 |
| 5. | The second wave , the one that can cause damage , moves at a slower four kilometers per second
第二种可能造成危害的波速度较慢，以每秒4千米的速度传播。 |
| 6. | Standard test method for measuring the p - wave speed and the thickness of concrete plates using the impact - echo method
用冲击回声法测量p波速度和混凝土板的厚度的标准试验方法 |
| 7. | 2 , the image of sn - wave velocity lateral variation is reconstructed in china continent by tomography method using 43646 sn rays
2 、用了43646条sn射线反演得到中国大陆上地幔顶部s波速度横向变化。 |

| 9. | 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
这样，影响了该方法的应用，因此，有必要从理论上寻找瑞利波速度跟强度或者固结度的关系式。 |
| 10. | 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条pn射线的走时反演出中国大陆上地幔顶部的p波速度横向变化和各向异性分布。 |
