Analysis of the development and future tendency of material thermal expansion coefficient |
| |
| Abstract: | In the precision engineering, the material thermal expansion coefficient is required to be more accurate. This paper comprehensively analyses the development and present conditions of material thermal expansion coefficient. After posing of the deficiency of traditional thermal expansion coefficient, it puts forward the new concept of accurate thermal expansion coefficient and technological problems, which need to be solved in theoretic and practical application. |
