据美国 Science,1999,283:1513报道,“世界上最小的秤”最近由美国、中国、法国和巴西科学家在美国佐治亚理工学院研制成功。碳纳米管是一类极其重要的纳米体系。对于碳纳米管力学性能的测定也是众多科学家研究的课题。最近的一些实验结果表明,碳纳米管的杨氏模量和理论计算值接近,达到10~(12)帕,与高定向 According to the report of Science, 1999, 283: 1513, “the smallest scale in the world” was recently successfully developed by the scientists from the U.S., China, France and Brazil at the Georgia Institute of Technology in the United States. Carbon nanotubes are a type of extremely important nanosystem. The determination of the mechanical properties of carbon nanotubes is also the subject of many scientists. Some recent experimental results show that the Young’s modulus of carbon nanotubes and theoretical calculations close to 10-12 (Pa), and high orientation
