The attenuation by absorption of seismic waves is closely relative to amplitude information and has higher sensibility if in comparison with other seismic information.
地震波的吸收衰减信息和振幅信息密切相关，与其他地震信息相比具有更高的灵敏度。

The relative current attenuation decibel value was used to indicate the microwave attenuation anisotropy.
从实验角度分析了微波衰减各向异性与力学各向异性之间的统计相关情况。

There is diffuse decreased attenuation of the cerebral cortex with a relative preservation of density in the thalami, brainstem, and cerebellum.
