查询词典 speed of sound

The results showed that,the sound pressure level increased significantly when narrow transverse groove was used;the effect of speed on the sound pressure level was greater than loading;the noise of S-shaped straight groove was lower,and the difference of sound pressure level between positive and negative rotation was small;the sound pressure level of 15° oblique groove was higher than 0° and 15° alternate groove,but the difference of sound pressure level between positive and negative rotation of 0° and 15° alternate groove was bigger.

结果表明，无论加刻什么类型的横向细沟槽，声压级都大幅升高；速度对声压级的影响程度大于负荷；在3种类型的横向细沟槽中，S形直沟槽噪声较小，且正、反转时声压级差异小；15°斜沟槽声压级较0°与15°交替排列沟槽略高，但0°与15°交替排列沟槽的正转和反转声压级差异较大。关键词：轮胎；轮胎噪声；胎面花纹；横向细沟槽中图分类号：TQ336.1；TB533+。2文献标识码：B文章编号：1006-8171(2009)

The free water in wood is very closely related to the density change of wood during drying, so that the sound speed measured by tap tone completely obeys the physical law relating sound speed and properties of solid materials. 2. When moisture contents are higher than the fiber saturation point, the weight changes or the moisture content changes of the wood can be estimated with high accuracy by measuring the changes of sound speed using the tap tone method.

试验结果显示：木材中之自由水分在打音时完全表现在生材之密度变化上，因此打音音速完全遵守音速与材质关系之基本物理定律，故在含水率高於纤维饱和点之生材状态，利用音速变化来推定木材重量变化或含水率变化具有相当高的精度，是合理可行的。

Gripper and carry it in its teeth and drum sounds dental students'rooms simultameous, enterprises'high, the power-on machine speed slower, easy to hear "" slapthe slapthe slapthe clossed of sound, though the sound is not big, but it is clear and crisp, if sound become vague, it is best to check both ends of the work of big spring and needle roller bearings are short of lubricating oil.

递纸叼牙与滚筒叼牙不并拢的不韵音很参差，开机运转时，机速较缓，便当听到&啪啪啪&的不并拢响不韵，虽然不韵音不不小，但很宏亮，如果不韵音变得暧昧，最坏查抄一下两头不小弹簧的处事环境及滚针轴承是否残润滑油。

Bone strength, determined using quantitative ultrasound measurement of bone speed of sound at the middle left tibial shaft, decreased significantly in the control group from 2,892 30 m/sec at baseline to 2,799 26 m/sec at four weeks. However, bone SOS of the exercise group remained stable (2,825 32 m/sec at baseline and 2,827 26 m/sec at four weeks). Despite improvement in bone SOS with exercise, there were no accompanying changes in markers of bone formation and resorption.

研究使用超音波测量骨骼声波速度来数量化评估骨骼强度，测量的位置是婴儿的中间左侧胫骨干，研究显示，对照组的婴儿显著减少了骨骼强度，从基线2，892 ± 30 m/sec降到四周时的2，799 ± 26 m/sec，但是锻炼组的骨骼SOS维持稳定(基线：2，825 ± 32 m/sec，四周：2，827 ± 26 m/sec)，虽然锻炼可以改善骨骼SOS，但是骨骼形成和再吸收指标并没有跟著改变。

Mach two equals twice the speed of sound.
