同时变频变幅的TFFP锯齿波扫描信号可以灵活地改变系统的扫描范围，进一步提高了系统的解调速度。
While the alterable frequency and scope sawtooth sweep signal for TFFP can neatly change the scanning range of the system, which is more improved the demodulation speed.
结果显示动态应变呈循环蠕变状态，蠕变的大小、速度与循环应力幅值有关。
The experimental results showed that the dynamic strain has feature of cyclic creep. Cyclic loading affected the creep and creep speed.
变幅杆作为振幅扩大装置，主要作用是把能量集中，将机械振动的质点位移或速度放大。
As the expansion device of amplitude, horn is used to focus energy and enlarge the mechanical vibration of the particle displacement or velocity.
