Abstract: Disclosed are a method for adjusting a signal of a display panel, a time controller integrated circuit, a display panel, and a storage medium. The method includes: converting first data into a first data voltage signal using a first data voltage, in response to a set condition being reached, sending the first data voltage signal to a chip on film integrated circuit, the chip on film integrated circuit identifies the first data voltage signal to obtain a second data; acquiring the second data from the chip on film integrated circuit, determining that the chip on film integrated circuit fails to identify the first data in response to the second data being different from the first data; and adjusting the first data voltage until a second data voltage signal converted from the first data using a second data voltage after adjustment being successfully identified by the chip on film integrated circuit.

Abstract: Disclosed are methods for preparing a high-performance soft magnetic composites and magnetic toroidal cores thereof. A spherical soft magnetic alloy particle is coated with an insulating layer to form a mixed powder, and the mixed powder is loaded into a mold and subjected to a compression molding. An external magnetic field is applied during the compression molding of the mixed powder, and the external magnetic field is parallel to a working magnetic circuit plane and perpendicular to a normal direction of the working magnetic circuit plane. Then a stress-relief annealing is performed to obtain the high-performance soft magnetic composite.

Abstract: An apparatus for direct analysis is based on solid ablation by a plasma jet. It includes a microwave plasma system, a gas transmission system, a sample carrying system, a signal collection system and a data analysis system. In the microwave plasma system both the microwave resonant cavity and the discharge tube are connected to the microwave power source. The gas transmission system is connected to the discharge tube; the sample carrying system is located below a gas outlet of the discharge tube. The signal collection system is configured to collect a spectral signal of a sample to be tested, and is connected to the data analysis system.
