Abstract: A shear testing system and method of thermo-seepage-mechanical field and engineering disturbance coupling under deep and complex condition are provided. The shear testing system can be used in conjunction with an axial pressure application device to simplify the structure, save costs, and facilitate a triaxial confining pressure—temperature—axial pressure—torsional shear coupled test on a rock specimen. The shear testing system can achieve the following three purposes. First, the shear testing system can convert an axial pressure into a torsional shear force through a transmission mechanism of a power conversion assembly. Second, the shear testing system can apply an axial pressure to the rock specimen fixed between two specimen fixing heads, through a pressure shaft of an axial pressure mechanism. Third, the shear testing system can apply a triaxial confining pressure and a temperature field to the rock specimen.

Abstract: A method for preparing an intelligent display film having a switchable viewing angle and a composite film containing the display film includes: mixing liquid crystal and a photopolymerizable monomer according to certain percentage content, wherein the ratio of raw materials is selected according to the refractive index matching ability between a conductive film and a polymer-dispersed liquid crystal layer as well as the characteristics of material components, and wherein the percentage content of the liquid crystal is 30-60%, the percentage content of the photopolymerizable monomer is 38-70%, the percentage content of a photoinitiator is 0.1-3.5%, the percentage content of a spacer is 0.
