| Abstract: | One kind of simple measurement method and experiment device of measuring the linear expansion coefficient of flexible material was introduced.Together with the original FD-LE expansion coefficient measuring instrument,the spring,cartridge and nib in ball-point pen were used to connect the material and dial indicator.The linear expansion coefficients of several flexible materials were measured by the improved-above instrument. |
| Keywords: | flexible material linear expansion coefficient instrument improvement |
