Through contrasting and analysing the experimental results from these methods, the paper summarizes the regularity of collapsing deformation and the shear strength index changes with the degree of saturation and stress, describes the collapsing deformation properties and strength characters of the collapsible loess in the course of moistening and drying, and describes the influence to collapsing deformation of loess from different paths of stress. Through performing monaxial compression test on samples with different paths of inundation and direction of press, proves the conclusion that collapse has nothing to do with the path of inundation and the collapsible loess has the prominent anisotropy characters.

Dielectric, piezoelectric and electrmechanical coupling properties of PZT and PSZT systems at high Zr content region were studied. The feature of high Kt and low Kp of PZT-based materials near F-AF phase boundary was exploited and examined, and electromachanical coupling anisotropy Kt/Kp is higher than that at the morphotropic phase boundary , Kt≥0.40, Kt/Kp≥3. 0. This phenomenon can be realized by electric field -induced AF-F phase transition and explained by coupling effect of two-sublattice in antiferroelectric unit cell.
