求翻译：过去几十年来，人们一直致力于研究铁电体宏观尺度上的物理力学行为。近年来，随着微机电系统的迅猛发展，铁电体在微纳观尺度上的物理力学行为也日益受到人们关注。是什么意思？

In the past few decades, people have been dedicated to study ferroelectric macro-scale physical and mechanical behavior. In recent years, with the rapid development of micro-electromechanical systems, physical and mechanical behavior of ferroelectrics on the scale of the micro-nano concept is also i

In previous 10 years, there has always been committed to studying ferroelectric-on macro-scales of physical mechanics. In recent years, with the micro-electromechanical systems (rail, rapid development in Microsoft Outlook, on the scale of the physical mechanics are also is a growing concern.

In the past for several dozens years, the people devote continuously in the research seignette-electrics macroscopic criterion the physical mechanics behavior.In recent years, along with the microcomputer electrical system series swift and violent development, the seignette-electrics in micro accept

Over the decades, people have been working on physical and mechanical behavior of ferroelectric body on a macroscopic scale. In recent years, with the rapid development of micro electro-mechanical systems, ferroelectric body in physical and mechanical behavior of the concept of micro-and nano-scale
