摘要
提出晶体四维状态效应新模型．重点分析了机电耦合效应与电磁效应的相似性．从而提出机电耦合二次、三次…感生效应的概念，以压电效应为例，从定性与定量两方面分析其变化规律，并通过静态下的实验给予证明．机电耦合大于等于二次感生效应的存在与应用，对研究与开发新型可逆变换型传感器、实现传感器与执行器集成化与－体化均具有理论指导意义．
A new model about material effect of four-dimensional state of crystal is advanced.The similarity of electromechanical effect and electromagnetic effect is specially analyzed, thusthe fundamental conception about ≥ 2 times induced effect of electromechanical coupling isproposed. its variation law is analyzed from qualitative and quantitative aspects,and has beenproved through static test. The existcnce of electromechanical induced effect has importanttheoretical guiding significance for study and development of new reversible transforming sensorand realization of sensactor.
