摘要:
An electrical method has been developed for estimating the coefficient of linear expansion of a solid. Application of longitudinal stress on wires results in typical lattice distortions. Measured adiabatic and isothermal stress coefficients of resistance, Poisson's ratio, Young's modulus along with standard values of density and specific heat of the material allow us to calculate its desired linear coefficient of expansion to quite a good accuracy.
