因为她是第一个飞行速度比声音传播速度还快的女性飞行员。
She was the first woman to pilot a jet airplane faster than the speed of sound.
温度的升高或降低对声音传播速度的变化并不产生明显的影响。
The speed of sound increases slightly with a rise in temperature and falls with a decrease in temperature .
温度的升高或降低对声音传播速度的变化并不产生明显的影响。
The speed of sound increases slightly with a rise in temperature and falls with a decrease in temperature. It is not affected by the pressure of the air.
我就是从那里了解了光比声音传播速度快的，因为声音总是和飞石差不多一样的速度。
That's where I learned that light travels faster than sound, which is almost as slow as a flying rock.
在1961年，美国制造商Convair生产出了可以达到0.91马赫的商用喷气式飞机，速度相当于声音传播速度91%。
In 1961, American manufacturer Convair released a commercial jet that could reach Mach 0.91, meaning 91 percent as fast as sound.
声音在水中的传播速度要比在空气中快。
Sound travels faster through water than it does through air.
声音在水中的传播速度几乎是在空气中传播速度的五倍。
声音在空气中的传播速度究竟有多快？
光的传播速度比声音快。
打雷时你先看到闪电，然后再听到雷声，这是因为光传播速度要比声音快。
In a thunderstorm you see the lightning first and then hear the thunder. This is because light travels very much faster than sound.

喷气式飞机的速度要比声音的传播速度快(声音一秒钟传播约1100英尺，也就是1小时传播760英里)。
Jet planes can travel faster than sound sound travels at about 1100 feet a second. That is about 760 miles an hour.
正面排气设计加快声音的传播速度，即使在大音量情况下失真度相对较低。
The AS8's bottom-firing and front-ported design means you'll hear quick, precise bass with low distortion, even at higher volume levels.
