Measuring the expansion coefficient of metal using single slit diffraction;

Influence research of different expansion coefficient plaster cast materials on resin denture surface roughness;

The influences of additives' thermal expansion coefficient on samples' boundary residual stress and mechanical properties were investigated.

The paper summarized a lot of literatures, and collected many data about thermal conductivity and thermal expansion coefficient.

The sintering temperature and thermal expansion coefficient of the LSGM sample were determined using dilatometer.

According to the survey data,the paper got short-term expansion factors and long-term expansion factors of bridge superstructure and proved its laws for reference.

The phylogeny and the tendency of the prestressed structures are analysed in this paper, and the function and status of prestressed cables are also immulated, the classification performance and state-of arts of prestressed cables are summarized and the importance of the research for linear expansion factor of the cables is proposed in this paper.
