The output of electron acoustic signal in the ferroelectrics is calculated on the basis of their piezoelectric properties. The results show that the magnitude of electron acoustic signal not only related with beam currents, beam power and modulation frequency, but also with sample properties especially electric parameters such as dielectric constant and spontaneous polarization.

That isn't to say that Linstead plays the acoustic guitar exclusively on-stage or in the studio; while the acoustic guitar is his primary instrument, Linstead also plays mandolin, violin, bass, acoustic piano, electric keyboards, various wooden flutes, and the bouzouki (a traditional Greek string instrument).

这就是说，Linstead只在舞台上或录音棚里演奏非电声吉他；虽然非电声吉他是Linstead主要演奏的乐器，他也演奏曼陀林、小提琴、贝斯、声学钢琴、电声键盘、各种木笛，以及布祖基琴。

In summary, various key experimental conditions in electron acoustic imaging of ferroelectric domains were systematically studied. The optimum experimental conditions to obtain EAI of domains with good quality and the factors important to image analysis have been presented. The piezoelectric vibrator model and calculation of motion equation are helpful for explaining the imaging mechanism and related experimental phenomena. The sample holder with variable electric field was designed. The domain movement of BaTiO〓 ceramics and crystal under lateral and longitudinal applied electric field and domain movement of PMN-PT crystal under longitudinal poling electric field were observed. The application of SEAM on revealing of ferroelastic domains, imaging of residual stress distribution in ceramics coatings and around the pores on the surface of ferroelectric ceramic composite have been reported respectively. All these works enriched the study of electron acoustic imaging and extended the application of SEAM in the characterization of materials.
