您要查找的是不是：
- negative amplitude attenuation constant 负振幅衰减常数
- negative amplitude attenuation 负值衰减系数
- Amplitude attenuation tomography is based on seismic ray tracing by using linear traveltime interpolation . 模型试算表明:它能对地层的品质因子和Q值异常很好的成像。
- The phenomena of amplitude attenuation and wave_shape aberrance arise from unsteady friction, while the steady friction term cannot reflect these phenomena. 说明非恒定摩阻的存在导致了水击压力波波幅衰减和波形畸变现象 ;而采用恒定状态下的摩阻关系式无法反映这个现象 .
- amplitude attenuation relationship 幅值衰减关系
- Study of Numerical Simulation on Amplitude Attenuation of First Arrivals in Cased-hole Acoustic Logging 套管井声波测井中首波幅度衰减研究
- The answer to my request was in the negative. 对我的请求的答复是否定的。
