Piezoelectric ceramic is a function material which can exchangeenergy between mechanic and electricity.
压电陶瓷是一种可实现机械能与电能相互转换的功能材料。

The matter flow must be produced in the way in which the stands exchangeenergy and matter with the energy flow of the external environment.
这种“物质流”必定是与外界环境的“能量流”进行能量、物质交换所产生出来的。

Along different directions, due to the differences in distance between atoms, force constant and exchangeenergy change rate, different magnetostriction appears.
