Results: High quality VR-3D images will be obtained by selecting 2 or 3 objects, appropriate range of attenuationvalue and opacity %.
结果：选择2或3个目标、合适的衰减值及不透明度的限值可获得良好的VR立体成像。

Based on the principle of sound attenuation to measure the sediment concentration of suspensions, the attenuationvalue of sound pressure must be detected.
基于声衰减原理进行水体含沙量测量的方法，需要测量声压的衰减值。

Especially, regularity as one of the constraints assure the flatness in passband and the high attenuation in stopband, even the value of stopband response is very close to zero.
