摘要 基于能量均分定理和悬臂梁理论,分析讨论了微悬臂梁进行热振动的物理模型。通过三个实例,介绍了热振动在纳米力学测量中的应用,其中重点阐述了单根纳米晶须的杨氏模量的热振动定量测量方法。 Based on the equipartition theorem and cantilever theory,we analyze and discuss the physical model of the thermal vibration for micro-cantilever. We induced three examples on the applications of thermal vibration on nano-mechanical measurement, and focused on quantitatively measuring the Young's modulus of a single nanowhisker by using the thermal vibration technique.
