Mine inclination measurement is a new technology for mine borehole measurement, and it is an important means for comprehensive advance detection and structural positioning. Due to its unique role in pre-exploration exploration of piezo ceramic tubes, a number of corresponding technical studies have

Sonar is a very important naval equipment, and it has received great attention from all countries with the using of underwater weapons such as submarines. Here, we don't discuss a specific equipment, nor do we involve too many mathematical concepts. Instead, we start with a simple physical principle

The main material of the traditional sonar array hydrophone is piezoelectric ceramics, and the development of new materials can greatly improve the sonar performance. Today's new materials are piezoelectric polymers and optical fibers. Among the piezoelectric polymer materials currently are used for

As an important equipment for detecting submarines, sonar has undergone decades of development. From the sonar equipment are used in the national equipment.the sonar technology researched and developed, the future development trend of sonar technology can be summarized as follows,piezo ceramic conti

A hydrophone is a transducer that converts an underwater sound pressure signal into an electrical signal. When the pressure (acoustic disturbance) on the piezoelectric material piezo ceramic tubes changes, the charge distribution inside the piezoelectric material changes proportionally and is reflec
