Abstract: A method, apparatus and optical device for detecting a relationship between an evanescent field and Goos-Hänchen shift, said method comprising: obtaining a potential field function of an evanescent field acting on total-reflection light according to physical meanings of a force function and the potential field function of light in the evanescent field (S101); obtaining a wave function of the perturbed total-reflection light by means of the Schrödinger equation by combining with the potential field function of the evanescent field acting on total-reflection light (S102); and comparing the wave function of the perturbed total-reflection light with a wave function of free total-reflection light with no action from the evanescent field, and determining a momentum gained by the total-reflection light under the action of the evanescent field, which is the same in nature as a momentum of the evanescent field (S103).

Abstract: An internal fixation plate for sternoclavicular join comprises a locating rod junction and the clavicle fixation segment, both with flat cross sections. The locating rod junction and the clavicle fixation segment are not in the same plane, and the transition segment connects in between the locating rod junction and the clavicle fixation segment. The clavicle fixation segment is of a long strip, and screw holes are designed in the clavicle fixation segment. The locating rod junction is movably connected to the cylindrical sternum locating rod, through the connector, and allows the sternum locating rod to rotate and swing relative to the locating rod junction. The internal fixation plate connects the clavicle fixation segment to the sternum locating rod through a movable connection, so as to prevent the sternum locating rod from scratching and enlarging the bone holes in sternum.
