本文提出了一种通过静电共振来测量微米纤维杨氏模量的方法.该方法无需借助昂贵的高精度微型传感器或者激光多普勒振动仪，而是直接通过光学显微镜测量来获得微米纤维悬臂梁的共振频率，进而通过欧拉-伯努利梁理论计算出其杨氏模量. 该测试方法有益于提高学生的综合实验能力，激发学生的学习兴趣，提升创新意识，自觉将物理思想和物理测量方法应用于新兴科技领域.

 A method based on electrostatic resonance for measuring Young’s modulus of microfibers is developed in this paper. The resonance frequencies of cantilevered microfibers are directly determined by using an optical microscope, rather than an expensive high-precision microsensors or laser Doppler vibrators used in previous studies. The Young’s moduli of microfibers are derived from Euler-Bernoulli beam theory by using measured resonant frequencies. This method is beneficial to improve the comprehensive experimental ability of undergraduates, stimulate their interest in learning, enhance their awareness of innovation, and help them to consciously apply physical principles and measurement methods to the new areas of science and technology.
