您要查找的是不是：
- Negative coefficients occur where there is a decrease in acoustic impedance across the reflecting interface. 当反射界面上下两侧的声波组抗降低时，反射系数就会出现负值。
- In the three-parameter velocity analysis,we first derive dip direction and dip angle of reflection interface from 3-D seismic data,then obtain mean square-root ve-locity. 在三参量速度分析中，需要根据三维地震勘探资料充求取地下界面的倾向和倾角，然后确定均方根速度。
- Keywords Isotimic graph;Interfac graph;Atomic orbit;Hybridiyed orbit; 等值图;界面图;原子轨道;杂化轨道;
- Having known the time dip angles in inlineand crossline directions,and the corresponding average velocity,we can compute thetrue dip direction and true dip angle of reflection interface. 如果知道纵测线和横测线两个方向上的时间视倾角，又知道地层的平均速度，就能求得反射层的真倾向和真倾角。
