The radial piston pump can adopt manual-control or electro-hydraulic proportional control to realize the control of constant flow, constant pressure, constant power and load sensitivity etc.
Theoretical results show that the piezoelectric sensing sensitivity of PVDF film is proportional to film thickness and inversely proportional to the elasticity constant S.
理论分析表明PVDF薄膜的声学灵敏度与膜的厚度和膜的弹性刚性系数成正比。

The results indicated that the sensitivity is appoximately proportional to the square root of the length of grating. And so does the result derived from Fourier analysis and spatial-frequency channel.
