| Abstract: | The linear expansion coefficient is an important parameter to characterize material expansion.Using YJ-RZ-4 digital intelligent thermal analyzer,the author measured the metal sample’s linear expansion coefficient by the dial gauge method.Through to measurement data analysis processing by the least square method and successive difference method,the expected result is obtained. |
| Keywords: | linear expansion coefficient dial gauge least square method successive difference method |
