【摘要】:熱振動(dòng)是一定溫度下納尺度結(jié)構(gòu)的固有運(yùn)動(dòng),對(duì)其動(dòng)力學(xué)行為有著重要的影響.當(dāng)空間進(jìn)入納米尺度,結(jié)構(gòu)呈現(xiàn)離散性,量子效應(yīng)、邊界效應(yīng)、范德華力等變得不可忽略,納尺度結(jié)構(gòu)在熱噪聲隨機(jī)激勵(lì)下的動(dòng)力學(xué)行為表現(xiàn)出眾多異乎尋常的特性.以碳納米管和石墨烯為代表的納尺度碳材料具有優(yōu)良的力學(xué)、電學(xué)和化學(xué)性質(zhì).在此介紹多種針對(duì)納尺度結(jié)構(gòu)熱振動(dòng)問(wèn)題的研究方法、及碳納米管和石墨烯的低溫?zé)嵴駝?dòng)、碳納米管的非線(xiàn)性熱振動(dòng)研究進(jìn)展.
[Abstract]:Thermal vibration is the inherent motion of nanoscale structure at a certain temperature, which has an important influence on its dynamic behavior. When the space enters the nanometer scale, the structure presents discreteness, quantum effect, boundary effect, van der Waals force and so on. The dynamic behavior of nanoscale structures subjected to random thermal noise has many unusual properties. Carbon nanotubes and graphene have excellent mechanical properties. In this paper, a variety of research methods for thermal vibration of nanoscale structures, low temperature thermal vibration of carbon nanotubes and graphene, and nonlinear thermal vibration of carbon nanotubes are introduced.
