1.The Poly Vinylidene Fluoride (PVDF) membrane was chosen to produce ultrasonic in transducer due to its higher sensitivity and better flexibility than other piezoelectric material. At the mean time, harmonic analysis to the PVDF film vibration was performed using ANSYS. The results show that the PVDF membrane can produce an ultrasound with a fixed resonance frequency.
2.Second, numerical simulation and qualitative analysis has been done for the synthetic jet flow field in different cases (different phase, amplitude and frequency), and gained many conclusions which are helpful for designing the synthetic jet actuator.
3.For the purpose of designing a high performance synthetic jet actuator, the performance of actuators has been investigated experimentally for a range of geometric parameters.

8.Study on Taste Electrochemical SensorⅠ.Characteristic Effect of Sweet, Sour, Bitter and Salty Substances on the Frequency of Electrical Oscillation Across a Liquid Membrane
9.It can be approved from the spectra that there existed enhancement of Raman scattering on Ag-coated LiCoO_2. Meantime, the Raman peaks of SEI components in Raman spectra had been analyzed. The components of SEI film were assignmented as Li2CO3、LiOH·H2O、LiF、ROCO3Li、COC group、LiO2Li et al. , which were all enhanced by SERS.
10.Heart sounds is heart throb process in, shut by the valve inside the heart, open, and the sound that the oscillatory place such as systole or diastole produces.
