The invention discloses a method for calibrating the power of a plate-type fuel element used for fuel consumption measurement, which calculates the flow rate of different coolants passing through an irradiation test device, and obtains the flow distribution coefficient of the inner and outer flow channels of the test section; uses the plate-type fuel element The nuclear power and the total heat release power of the test section are obtained to obtain the initial values ​​of the nuclear power of the fuel element core and the gamma heat release rate of each structural material, and the heat source and distribution in the test section are preliminarily determined, and the calculation model is established by using the geometric structure model; Iterative calculations determine the gamma heat release rate of the material; determine the nuclear power of the fuel element; determine the burnup of the fuel element. This method is used to determine the real-time burnup value of the test fuel element to ensure the realization of the fuel element burnup radiation index. Through certain analysis methods and methods, the influence of gamma heat release of structural materials is removed, and the heat balance method is used to reduce the fuel radiation. The error of the nuclear power of the fuel during the test, so as to realize the calibration of the nuclear power of the fuel during the irradiation test for the measurement of the burnup.

The invention discloses a heater based on a diesel filter. The heater comprises a filter body. The top of the filter body is movably connected with a heating top cover, and the middle of the inner wall of the heating top cover is fixedly connected with a heating bar. A temperature sensor is fixedly connected to the inner wall of the heating top cover and one side of the heating bar. A storage battery and an electric quantity sensor are fixedly connected in the heating top cover. The heater based on the diesel filter avoids the situation that a diesel filter at the current market does not have the heating performance, the problem that in winter, the inner temperature of the diesel filter is low is solved, and the situation that unable starting of a vehicle is extremely prone to being caused is prevented. Normal work of the vehicle is guaranteed, automatic heating treatment is achieved, and unnecessary difficulty is lowered; and normal usage is guaranteed for users, the electric quantity in the storage battery is monitored in real time, and normal work of the heater is guaranteed.

The invention relates to a method for measuring shaft torque, rotational speed and power parameters of a power device. Under the premise of no load, two sets of image sequences S11‑S1n and S21‑S2n are collected synchronously; after loading, two sets of image sequences A11‑A1m and A21‑A2m are collected synchronously; among A11‑A1m and A21‑A2m Any pair of images A1i and A2i that have a synchronous corresponding relationship; A1i and S11‑S1n are correlated to obtain the reference image S1i with the highest correlation; A2i is correlated with S21‑S2n to obtain the most correlated reference image S2j; Find the reference image S2t corresponding to the time synchronization of S1i in S21‑S2n; the distance between S2t and S2j is the torsional displacement Δs at both ends of the shaft; the torque is obtained by . The invention has higher precision and simple structure.
