意味（1）

(physics) A strain expressed in terms of parts per million

意味（2）

(materials science) The root mean square of the variations in the lattice parameters across the individual crystallites, usually across microscopic distances, <ϵ²>^(1/2). By definition, it cannot be negative. In contrast, macrostrain refers to the overall change in the lattice parameters caused by a composition change or temperature change or pressure change.

The analysis of diffraction-line broadening is one of the most powerful methods to quantitatively analyze defects in crystalline materials. Values for crystallite-size and microstrain parameters can be obtained according to a variety of methods.
