声波

A true diffusor scatters sound waves in different directions based on their frequency, rather than merely redirecting all waves in the same direction.

一个真正的diffusor散射声波在不同方向的基础上他们的频率，而不是仅仅重定向所有海浪的方向是一致的。

They sound great straight out of the iPod but really shine with the Hornet in the loop adding sonic weight, better depth in the three dimensional sound and mellowing out the top end.

他们听起来伟大直接出于iPod 但真正地发光与大黄蜂在圈增加声波重量、更好的下潜在三维声音和mellowing 在顶端之外。

The processing and interpretation of crossed dipole array acoustic logging data and its applications in anisotropy were also described.

详细描述了正交偶极阵列声波测井技术的特点；介绍了该技术资料采集的方式及针对不同特性地层的参数选择原则。

Diffraction is the process by which sound waves experience a change in their direction of propagation after encountering an obstacle; it is equivalent to a bending effect.

衍射是声波遇到障碍物后改变其传播方向的一种过程，相当于一种弯曲作用。

Further support came with the discovery of polarization, which indicated that the undulations of a light wave were transverse to the direction of propagation and were not longitudinal, as were sound and water waves.

更进一步的支持随光的极化发现而来，表明对光的传播方向来说光波波动是横向的而不是纵向的，如同声波和和水波那样。

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
