摘要：

We show that the spatial resolution of quantitative chemical mapping is determined by the larger of two factors: the periodicity of the chemically sensitive reflections, or the size of the unit cell adopted for pattern recognition. Under appropriate chemically sensitive imaging conditions, nonlocal effects due to dynamical scattering and Fresnel fringing are insignificant. even when artifically large discontinuities in the sample projected potential are introduced.
