sound impedance meaning in English
声阻抗
Examples
- The analytical mode is based on the theory of sound propagation in layered media . the concept of equivalent parameters is established . the absorption of sound energy by damping layer ' s is represented by use of complex sound impedance
解析模型以分层介质中的波动理论为基础，建立了等效参数的概念，并运用声阻抗的复数表示法把阻尼层对介质层声能吸收的影响都考虑进去，通过比较敷设消声覆盖层前后多层传递损失的差异来获得消声层的效率。 - " utilization of multi - attribute transformation in predicting well logging parameter " has transcended many traditional methods of reservoir research in many aspects , and possessing many outstanding technology superiority , which are showed below : ( 1 ) it takes new technology thought - " date - driven law " as the guidance , and inherits and synthesizes forefathers successful technology formed in many years . ( 2 ) ' it directly calculates the well logging parameter by way of the multiple attribute transformation , rather than by way of the sound impedance , like the porosity , while the way before is to make further estimates of the sound impedance from the seismic inversion result so that the result suffers the influence of many factors . ( 3 ) the usefulness of the seismic attribute is drawn from the seismic data , rather than the traditional poststack seismic data after nonlinear a transformation
“ ；利用多属性变换预测测井参数”在很多方面超出了传统意义上的储层研究方法，具有突出的技术优势，表现在： ( 1 )它以新的技术思想? ? “数据驱动法”为指导，继承并综合利用了前人多年来形成的成功技术： ( 2 )它是直接通过多属性变换预测测井参数，而不是通过声波阻抗，如空隙度，以往的做法是从地震反演结果中的声波阻抗做进一步的模拟估算，其结果受到诸多因素的影响； ( 3 )所用到地震属性是从地震数据中提取的，而不是传统的迭后地震数据本身。
