An X-ray focal spot shape evaluation apparatus 10 is an apparatus for evaluating an X-ray focal spot shape including an X-ray focal spot size on a target 22 of an X-ray source 20, and includes an imaging unit 11 and an operation unit 12. The imaging unit 11 acquires a phase contrast image in a range including an edge of an object 30 disposed on a propagation path of X-rays generated on the target 22 of the X-ray source 20. The operation unit 12 evaluates the X-ray focal spot shape on the target 22 based on at least the phase contrast image, a linear attenuation coefficient of the object 30, and a refractive index of the object 30. Thus, an apparatus and a method capable of easily evaluating a focal spot shape including an X-ray focal spot size on a target of an X-ray source are realized.

The invention relates to the technical field of test question difficulty prediction, and provides a circuit test question difficulty assessment method and system, and the method comprises the steps: obtaining a target parameter from a circuit test question, and carrying out the extraction of knowledge points based on the target parameter; according to the extracted knowledge points, classifying the knowledge points according to six categories of memory, understanding, application, analysis, evaluation and creation of a Bloom cognitive process dimension; determining the weight of each extracted knowledge point through an analytic hierarchy process, and calculating the assignment value of each knowledge point; according to the assignment value of each knowledge point, the classified knowledge points and an analytic hierarchy process, determining the weight of six categories of each knowledge point, and calculating the assignment value of each category of each knowledge point; and calculating a difficulty score of the circuit test question based on the score of each category of each knowledge point, and evaluating a difficulty coefficient of the circuit test question based on the difficulty score of the circuit test question. The difficulty of the test question evaluation process can be effectively reduced, the accuracy of test question difficulty evaluation can be effectively improved, and the evaluation efficiency is effectively improved.

This application discloses a method for determining a display mode and a vehicle, relating to the field of vehicle control technology. The method includes: determining the first importance of a vehicle function to be displayed to the occupants based on their attribute information; determining the second importance of the vehicle function to the current driving process based on the vehicle's current driving scenario; determining the vehicle's usage preference for the vehicle function based on its historical usage information; and fusing the first importance, second importance, and usage preference levels to determine the target display mode corresponding to the vehicle function based on the fusion processing result. The technical solution of this application embodiment can make the target display mode more closely match the actual driving conditions of the vehicle and the actual needs of the occupants, thereby improving the convenience and experience of occupants using vehicle functions.
