The invention provides a method and device for measuring the elasticity of hardened cement for cementing of oil-gas wells. The measurement method comprises: determining the loading and unloading rates of the hardened cement; determining the maximum loading on the hardened cement; determining the experimental temperature and the experimental pressure of the hardened cement; establishing a stress-strain curve for the hardened cement; and describing the elasticity of the hardened cement with the degree of strain recovery of the hardened cement in different cycles, and describing the mechanic integrity of the hardened cement with the degree of damage to the hardened cement in different cycles. The invention further provides a device for measuring the elasticity of hardened cement for cementing of oil-gas wells. The measurement method and device of the present invention provide a universal comparing platform for research on hardened cement modification as well as examination of domestic and foreign special cement slurry systems, which is of great significance in evaluation of well hole integrity and well life.

Embodiments of the present invention relate to a profiled light guide plate, a backlight module and a liquid crystal display device. In the profiled light guided plate according to the embodiments of the present invention, because the reflectivity of the profiled assembly is less than that of the light entry assembly, the emergent angle of the light beam entering into the profiled assembly from the light entry assembly is larger than the incident angle thereof, which causes the light beam entering from the light entry assembly into the profiled assembly to converge towards the central part of the profiled assembly, away from the ramp of the profiled assembly, thereby decreasing the amount of light leakage from the ramp.
