1. Use the Frequency Spectrum (FFT) display to measure the approximate value of the fundamental frequency of the wire on the Sonometer.

使用频谱（FFT）显示测量振动频率计上金属丝基频的近似值。

2. 1.Set the Sonometer at the edge of a table so the tensioning lever extends beyond the table.

将振动频率计置于桌子边缘，使张力控制杆伸出桌面。

3. Design and fabrication of sonometer

4. Methods An ultrasound bone sonometer, Omnisense (Sunlight Medical Ltd, Israel), was used to measure the bone speed of sound (SOS) of tibia in 157 Shanghai infants, and then compared with those of Caucasian.

方法采用以色列Sunlight公司生产的Omnisense定量超声仪,对157例新生儿进行胫骨声波速度(speed of sound,SOS)测量并与白人婴儿比较。

5. In this activity, a Driver Coil connected to the Power Amplifier is used to vibrate a thin wire that is stretched over two “bridges” on a Sonometer.

本实验中，采用一个与功率放大器相连的驱动线圈来使绷紧在振动频率计两桥臂上的细金属丝产生振动。

6. Through hard work and struggle and still be able to play music in the lives of the most beautiful sonometer, you will still be won enthusiastic applause.

通过勤奋和拼搏，仍然能奏出生命乐章中的最美弦音，你仍然会赢得热情的喝彩。
