In the article a optical system was developed by the newest RC microscope with the schlieren method, which made the figure of appearance excellent colour and lustre and fine third dimension. The special cylindrical and cubic crystal growth cell was designed and the temperature-control system was developed to cooperate with the cell. Radial thermal gradient was formed in the cylindrical cell while transverse thermal gradient in the cubic cell, which was prepared for finding new effects.

Calculations on the basis of the self-consistent approximation are used to study the effects of slit cracks, elliptical cracks and penny-shaped cracks. The influence of slit cracks on the elastic moduli under all kinds of loading conditions is discussed by Betti's reciprocal theorem and Irwin's relation describing the released energy rate of fracture to the stress intensity factors. The friction between the cracks' surfaces is taken into account for the closed cracks.
