声波

And, he adds, tests have shown that hungry predators are not attracted by the acoustic pings.

他还补充说，测试表明饥饿的捕食者并不会被声波脉冲所吸引。

What we want to know is if they can detect those rumbles in the ground.

我们想知道的是他们是否能检测到地面上这些次声波。

But if you are too far apart from because the voice wave scatters you also can hear an original voice

但如果你距离的太远由于声波的分散你也就只能听到原声了

Sound is like clay that he sculpts to his purpose.

声波很喜欢这个按个人意图由自己组装而成的身体。

For strong disturbance case in which Δp is set to be 5, by examining the distributions of relevant physical quantities along radial direction and the normal of wave front, we can infer that the slow wave introduced by the strong pressure pulse steepens into slow shock during the propagation process.

与二维情形类似，沿由源区出发的径向，可以分辨出压力脉冲增长相所引起的前导快波与后随慢波的传播，同时还可观察到压力脉冲恢复相所导致的快模磁声波的传播，由于传播速度的差异，该波动在向外传播的过程中逐渐超过后随慢波。

If Doppler ultrasound is used, however, you may be able to hear a "whooshing" sound as the echocardiography machine converts the echoes into sounds that can be heard and which the doctor can use as information about the flow of blood through your heart.

但如果使用多普勒超声波，患者就可能会听到&嘶嘶&的声音。这是因为这是超声波心动图仪会将反射回来的声波转换成了人耳可以听到的声音，医生也可以将这种声音作为血液流过心脏的特征性信息。

Finally, the parameters, such as density, thickness of porous media, thickness of steel of each material in air and porosity, pore size, thickness of porous materials, thickness of steel and incident angles in water were investigated and also the influence on the sound absorption and insulation were discussed.

最后，分别就空气中以及水中的材料参数，分门别类的观察其对吸音与隔音的影响。在空气中所讨论的参数，有多孔材密度、多孔材厚度、钢材厚度。在水中所讨论的参数，有多孔材孔隙率、孔隙尺寸、多孔材厚度、钢材厚度、声波入射角度。

Through air-borne sound is a continuous wave, wave sounds.

详细说明：声音是通过空气传播的一种连续的波，叫声波。

In this paper, we study nonlinear perturbation analysis of mesoscale verticalcirculation and evolution equation by means of f plane, non-hydrostatic balance andfilter model. Outstanding nonlinear characteristic of mesoscale disturbance invertical direction, we obtain nonlinear symmetric disturbance equation anddisturbance amplitude s evolution equation by use of multi-scale and singularperturbation technique.

中文摘要：本文采用f平面、非静力平衡、滤声波模式，讨论了大气中尺度非线性动力学方程，通过尺度分析重点突出了扰动在垂直方向上的非线性特征，从而得到了对称扰动非线性方程，运用多重尺度方法和摄动分析讨论了对称扰动非线性重力惯性波的演化过程，得到非线性重力惯性波振幅演化服从广义的非线性Schrdinger方程。

The crossing channel in a cased well is a column filled with fluid in the cement layer between the steel pipe and formation.

非轴对称井孔声场研究是近年来声波测井领域的热点之一，本文着重于带窜槽的套管井声场研究。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

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。
