查询词典 waves

The surface waves propagate with a phase velocity which is always less than the velocity of ectromagnetic waves in free space.

面波传播速度的阶段，始终是比ectromagnetic波在自由空间速度减少。

The results of the spectrum analysis show that the first wave in the harmonic waves is preponderate in the harmonic waves, the significant areas are North, Northeast, South-west and South of Chain, and the maxium values of amplitude occure in July and August.

对各站每年月雨日序列的波谱分析表明，我国大部分地区年周期的(第1谐波)振动在与其余波动比较中占绝对优势，显著地区是华北、东北、西南及华南地区，振幅最大值出现在7—8月份。

Radio astronomy is different from most other forms of observational astronomy in that the observed radio waves can be treated as waves rather than as discrete photons .

射电天文不同于大多数其他形式的观测天文学中所观察到的无线电波可被视为波，而不是离散的光子。

This approach has the advantage that the contact discontinuity in each local wave pattern is always fixed with speed zero and the rarefaction waves and shock waves are located on either side.

这种方法的优点是每个局部波形中的接触间断速度都为零，并且疏散波和激波分别位于时间轴的两侧。

The transmission of visual images of moving and stationary objects, generally with accompanying sound, as electromagnetic waves and the reconversion of received waves into visual images.

电视：传输通常配有相应的声音的运动和静止的物体的视觉图像的电磁波，并将其转变成视觉图像

On the basis of the result of regular waves, the reflection coefficient of the wave absorbing structure under the action of irregular waves is also analysed.

并在规则波的基础上将成果推广至不规则波作用下的情况。

In this few decades, scholars paid attention to the research of Bragg reflection in regular waves. Thus, this study aimed to discuss the Bragg reflection in irregular waves. EEMSE is a numerical model based on evolution equation for mild-slope equation developed by Hsu et al.

以往关於系列潜堤之布拉格反射研究，在规则波方面的理论、数值研究与分析都渐趋成熟，而实际应用於海岸保护时需考虑波浪为不规则波，因此本文之重点在於探讨不规则波下之布拉格反射。

The interaction between waves and muddy bottoms, which dominate the dynamic processes in muddy coastal area are studied in this dissertation. Special contributions are made to a better understanding of the transformation of regular and irregular waves and the mass transport of mud.

在淤泥质海岸动力因素与淤泥质底床相互作用的过程中，波浪与泥床的相互作用占有主导地位，本文对波浪与淤泥质底床的相互作用进行了较深入的理论与实验研究，着重探讨了规则波、不规则波在泥床上的传播规律以及底泥在规则波、不规则波作用下的质量输送现象。

In this paper it is believed that the onset process is from the unorderly sound waves generated by heated gases, through ordering the sound waves, regenerator onset in a high natural frequency, followed by steady oscillation whose frequency is controlled by resonance tube.

本文认为热声热机的起振过程是从气体被加热产生杂乱的声波开始，经过声波的规则化先从回热器的高频率自激振荡振动，继而扩展到以谐振管内气体固有频率为主导的整个系统的稳态起振。

Because radio waves travel at 186,000 miles per second and sound waves saunter along at 700 miles per hour, a broadcast voice can be heard sooner 13,000 miles away than it can be heard at the back of the room in which it originated.

无线电波传播的速度为每秒186，000英里，而声波传播的速度仅为每小时700英里。在13，000英里以外收听广播的人，能比在播音室后部的人先听到播音员的声音。

There had been a moment during the breakfast meeting, though, after the backslapping and the small talk and when all of us were seated, with Vice President Cheney eating his eggs Benedict impassively and Karl Rove at the far end of the table discreetly checking his BlackBerry, that I witnessed a different side of the man.

那次早餐会期间，在表示过关心和寒暄以后，我们所有人坐了下来，我注意观察了一下，副总统切尼面无表情地吃着班尼迪克蛋（Eggs benedict，源自美国，以英式松饼、火腿、水煮蛋以及荷兰酱组合而成），卡尔。罗夫在餐桌的远端谨慎地经常查看他的黑莓手机，我目睹了他所不为人知的一面。
