It is shown that the "damping" effect mainly exists in the zone of 0.5d from the impingement wall, and there are positive as well as adverse pressure gradient in the radial direction.
表明壁面的“阻尼”影响主要集中在近壁面0 . 5D以内，在径向上流动既有顺压梯度，又有逆压梯度。
The normalized form of shear modulus vs. strain amplitude will be shown by a single curve, and that of damping ratio vs. strain amplitude by a family of curves or a band zone with shrunk ends.
经归一化后，前者在平面上表示为单一的一根曲线，后者则表现为一簇曲线或两端是尖灭、。
