实际钻井结果证明，在研究区采用基于叠前弹性阻抗反演的LMR技术能够有效地识别含水与含气储层。
Actual drilling information shows that LMR technology based on elastic impedance inversion can effectively identify water and gas layers.
忽略各向异性影响的各向同性弹性阻抗公式不能正确地描述各向异性介质中弹性阻抗随入射角和方位角的变化。
The formulae for isotropic elastic impedance neglecting the effects of seismic anisotropy can't describe accurately the variation of elastic impedance with incident Angle and azimuth.
小鼠再通过吸入乙酰甲胆碱激发，并记录随后10分钟的呼吸系统阻力，采用每一侧阻抗测量评估呼吸弹性度（H）。
The mice were then challenged with inhaled methacholine and respiratory system impedance tracked for the following 10 minutes. Respiratory elastance (H) was estimated from each impedance measurement.
