Abstract: The invention discloses a method, a system, an electronic device, and a storage medium for determining performance of a power battery. The method includes the following steps: acquiring historical data of the power battery in at least two charging processes; determining, according to historical data in one charging process, a dQ/dV curve and a direct current internal resistance corresponding to said charging process; calculating a relative change rate of internal resistance capacity in any two charging processes; and determining the performance of the power battery according to the relative change rate of internal resistance capacity and a relative change rate of internal resistance capacity range corresponding to fault type. The invention can effectively determine whether the performance of the power battery is abnormal by combining, in the two charging processes, the target peak value of a dQ/dV curve of the power battery and the change in direct current internal resistance.

Abstract: The invention discloses a method for screening a therapeutic target of acute radiation-induced gastrointestinal syndrome and use of TIGAR target in the preparation of a medicine for treating radiation-induced gastrointestinal syndrome. The CreERT-loxP transgenic mouse model is used, in which quiescent intestinal crypt stem cells are effectively promoted to proliferate after exposure to high-dose ionizing radiation, to screen a therapeutic target that still has a therapeutic effect for radiation-induced gastrointestinal syndrome 18-24 h after ionizing radiation. Gene splicing occurs in particular cells in the CreERT-loxP transgenic mice only after the injection of tamoxifen, thereby regulating gene expression. The actual situation of initial exposure and then treatment after a nuclear accident is well simulated, so the invention is of great practical significance.
