The invention relates to a graphical recording method, in particular to a graphical recording method for force value tests. The graphical recording method comprises a regular value depictpoint method, a regular force value measuring method and an additional depictpoint method, wherein the regular force value measuring method compares continuously acquired force values measured for three times to determine the time of generating a wave crest and a wave trough and corresponding force values; and the additional depictpoint method is to perform additional depictpoint on the corresponding force values of the wave crest or the wave trough determined in the regular force value measuring method in the regular value depictpoint method. The method aims to design a graphical recording method for the force value tests capable of accurately reflecting a force value variation curve of the whole measuring process. Compared with the prior art, the method has the advantages of good constant velocity of test recording graphs, true and reliable force value variation and the like.

The invention discloses an optical temperature sensor and a temperature measurement method. The temperature sensor comprises a housing, and the interior of the housing is provided with a first optical fiber collimator and a second optical fiber collimator. At least one wave crystal plate is disposed between the first optical fiber collimator and the second optical fiber collimator, and two sides of the wave crystal plate are respectively provided with polaroids in a parallel manner. Light passing through the first optical fiber collimator enters the polaroids vertically. The temperature measurement method comprises the steps: carrying out the accurate temperature calibration of the sensor, building the corresponding relation between the temperature and a central wavelength, and determining to-be-measured temperature through detecting the central wavelength of the outputted light. The sensor and method obtain the specific wave crest because the sensor and method can carry out the processing of the incident light through the polaroids and the wave crystal plate, obtain the environment temperature through detecting the central wavelength of the specific wave crest, and improve the temperature measurement stability of the sensor.

The invention provides a degradable magnesium alloy stent, and belongs to the technical field of medical instruments. The degradable magnesium alloy stent comprises a plurality of main body supporting rings arranged at intervals, each main body supporting ring is of an annular structure, and every two adjacent main body supporting rings are connected through a plurality of connecting bodies; the main body supporting ring is formed by sequentially connecting a plurality of wave crest sections and wave trough sections, the wave crest sections and the wave trough sections are connected through transition sections, at least part of the wave crest sections (3) are of a structure with at least two arc-shaped vertexes, and the section width of the wave trough sections is larger than the average section width of the main body supporting ring. The multiple arc-shaped vertex structures of the wave crest sections increase the deformation allowance of the wave crest sections; the section widening design of the trough section improves the structural strength of the trough section; in the radial expansion process, stress and deformation can be dispersed and concentrated through the arc-shaped vertex structure and the section widening design, the degradation rate difference among the wave crest section, the wave trough section and the transition section is reduced, and the failure of the whole stent caused by the fact that the wave crest section and the wave trough section are degraded before the transition section is avoided.
