f/Hz f A0 Frequency f/Hz Drive signal U/Hz B A Amplitude A/V Fig.3 Diagram of testing resonance frequency System Design Part The materials of vibrator always are carbon fiber, invar and fused quarz.They all have good resonance sharpness(Q value).
Table 1 is comparison of three kinds of materials’ low temperature coefficients.
Because carbon fibre material’s price was cheap, the long time use was not easy to fatigue, and the proportion of lower temperature coefficient was small, so it was more suitable for oscillator materials.

Manufacturers are suggested to make use of reproducible or renewable raw materials and low energy value materials as much as possible.
Recycle of raw materials of waste products.
At the primary level of recycle, materials are recycled in line with its original use; at the second level of recycle, the use level of materials is lowered after recycle; at the third level of recycle, materials are reused after processing, for example, plastic resolved to be other raw materials.
The result is the maximal use of materials and energy.
