Finally,the mechanism for the effect of the updraft restraint of the hailstorm on micro-physical processes is analyzed.

许焕斌等 [3]指出，爆炸产生的冲击波和声波对上升气流有动力抑制作用，许焕斌 [7]还提出爆炸影

For example, although the fundamental of a trumpet is centred around 1200Hz, it generates strong harmonic components beyond 8kHz for the upper notes, with the implication that the harmonic series continues well into the ultrasonic region.

举个例子：虽然小号的中心频率在1200Hz左右，但它可以演奏在8KHz左右的高音，并可衍生出超声波范围的泛音。

Sound waves humans can hear have a frequency limit of 20,000 hertz.

人类能够听到的声波频率限制是20000赫兹。

It uses very high frequency sound waves to create an image of part of the body.

它使用的甚高频声波，以创造一个形象的身体部分。

The application of the permeability obtaining with stoneley-wave inversion in those complex lithology reservoirs with lower porosity and permeability shows that the permeability from stoneley-wave is a good reference to divide into zone for those reservoirs with relatively good wellbore conditions, big sediment thickness and good homogeneousness. This enlarges the application scope of acoustic logging.

斯通利波渗透率在低孔、低渗透性复杂岩性储层的应用结果表明，对于井眼条件相对较好、储层发育厚度大且均质的该类储层，可参考斯通利波渗透率进行储层的有效性划分，从而拓宽了声波测井的应用范围。

You can also download a Sonic Update Manager hotfix from Roxio itself that could possibly fix your problem.

您也可以下载一个声波更新经理修补程序，由Roxio是本身可能解决你的问题。

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。
