消费蒸汽在第一次审判，声称必须少于五十五磅每马力小时；率明显高于声称为hult引擎。

Experimental results of the second harmonic sound pressure level(SPL2)curves in frequency domain show that Prof.MAA's theorydescribes the behavior of the second harmonics satisfactorily in whatis called "Steady Region" of standing wave field.

频域内，大振幅驻波场二次谐波声压级曲线的实验结果，确认马大猷教授的理论为驻波场&稳定区&的极好描述，所提理论在本实验研究中，得到了肯定结果。

New York is about to become quieter at least a little, the noise code has been revised for the first time in 30 years, and now has new restrictions on trucks and residential neighborhoods, even rings in the lugholes on robot, more than ten minutes of barking could result in a ticket for the owner

The infant, during the latter portion of her rdeal, pierced the air with its wailings and screams; she strove to hush it, mechanically, but seemed scarcely to sympathise with its trouble.

Due to the cooling-water tube diameter of the generator is too small, the velocity of cooling-water is also too low, if we only use the travelling period difference of one emmission and reception, the propagation time will be too small to test. Then, we select ultrasonic circulation method as our concrete plan.

由于发电机冷却水引水管的管径小，冷却水的水流速度低，利用单次发射和接收的时间差检测时，传播时间差极其微小，故作者首次提出利用声循环法来检测大型汽轮发电机定子线棒冷却水流速。

He was for once without words himself, and he pressed the tobacco diligently into a ball between his thumb and forefinger, and picking up his pipe he fitted the bowl.

这一次，王龙自己反而一声不语起来。他一个劲儿地用拇指和食指捏着烟草，捏成了一个团儿，然后又拾起烟袋，把摔掉的烟锅安好。
