Weighted Hardy Space and Weighted Norm Inequalities of the Area Integral;

Using the Calderon-Zygmund operator theory,we obtain a Calderon-type representation theorem,and a generalized area integral characterization for Hardy spaces is obtained by its application.

The vapor-liquid contact and interfacial area on the valve tray were investigated on the basis of the mechanism of bubble deformation and breakage in the turbulent liquid.

By using the concept of ”coherence area”, we standardized three familiar statements about the spatial coherence criterion on a photon correlation spectrum measurement system.
