In the aim at developing and utilizing ferrous mill tailing resources to save energy, protect environment and develop sustainable society, the research of replacing natural sand for ferrous mill tailing into concrete are carried out. Concrete mixed with ferrous mill tailing is called ferrous mill tailing concrete. The study results show the compressive strength of ferrous mill tailing concrete with grade from C20 to C40 is nearly equal to that of common concrete though its dump and divergence decrease little. Through adding in suitable volumes of water reducing mixture, fly ash and slag powder, its workability is improved and satisfies the practical requirement.

The tilted beam illumination method is used to improve the resolution comparing with the axial illumination mode. Using this advantage, a restoration method of several tilted beam images covering the full azimuthal range was proposed by Saxton, and experimentally examined. To make this technique more reliable it seems that some practical problems still remain. In this report the restoration was attempted and the problems were considered. In our study, four problems were pointed out for the experiment of the restoration. (1) Accurate beam tilt adjustment to fit the incident beam to the coma-free axis for the symmetrical beam tilting over the full azimuthal range. (2) Accurate measurements of the optical parameters which are necessary to design the restoration filter. Even if the spherical aberration coefficient Cs is known with accuracy and the axial astigmatism is sufficiently compensated, at least the defocus value must be measured. (3) Accurate alignment of the tilt-azimuth series images.
