Abstract: A nuclide identification method, a system and an electronic device are provided, which relates to the field of nuclide identification. According to statistical characteristics, a background probability density function and a Compton probability density function in a ROI are determined. An energy Bayesian factor and a time Bayesian factor are determined based on energy and time interval information in a sequence of the nuclear detection events obtained by measurement. By combining the two factors, Compton plateau can be effectively identified and distinguished.

Abstract: A method for in-situ calibration of a fixed radiation dose rate instrument is provided, comprising: in a reference radiation field, calibrating a standard device, a first device to be calibrated to an nth device to be calibrated under a proposed database type, and obtaining a response signal of a first nonhomogeneous extended field generated by a first radiation source, and then establishing a database about type-relative position relationship-statistical data; generating a second nonhomogeneous extended field by a second radiation source with the same type as the first radiation source during in-situ calibration; and searching the type of a current device to be calibrated, and obtaining a final in-situ calibration factor of the current device to be calibrated according to a value in the database corresponding to the type.

Abstract: The present application relates to a clamping type game operating handle. The clamping type game operating handle comprises a left handgrip, a right handgrip and a bearing balance seat, the right handgrip and the left handgrip are mutually complementary in structure; and the left handgrip (10) utilizing the front tension spring (40) and the right handgrip (20) utilizing the back tension spring (50) perform telescopic movement in the left-right direction corresponding to the bearing balance seat (30). According to the clamping type game operating handle, a user can stably fix an electronic device by gripping the handgrips, thereby preventing palms or fingers from excessively occupying a limited screen space of the electronic device, not only ensuring the experience effect of a game, but also fully releasing the palms or the fingers.
