Abstract: Provided are an experimental apparatus and method for regulating and controlling the Zeeman transition of magnetic resonance. The method includes: generating a constant background magnetic field by using a magnetic shielding cylinder, a background magnetic field coil, and a constant current source, and controlling a Larmor precession frequency corresponding to the background magnetic field to be equal to a frequency of a sinusoidal signal output by a radio frequency signal source; adjusting the amplitude of a signal output by a radio frequency signal source of a pump-probe atomic magnetometer to set a radio frequency signal to be a ?/2 pulse or a ? pulse; and then controlling the radio frequency signal source to output a series of sinusoidal radio frequency pulse strings having the same initial phase. The Zeeman transition of magnetic resonance is regulated and controlled by adjusting the time interval between the radio frequency pulse signals.

Abstract: Provided are a battery module, a battery and a power consuming device. The battery module comprises: a plurality of battery cells arranged in a first direction; a heating film extending in the first direction and attached to a first wall of each of the plurality of battery cells, the first wall being parallel to the first direction, the heating film being configured to heat the plurality of battery cells; and a protective film extending in the first direction and attached to a first surface of the heating film away from the battery cell, the protective film being configured to protect the heating film. According to the technical solutions of the embodiments of the present application, the heating film inside the battery can be physically protected to prevent metal wire in the heating film from being damaged or broken.

Abstract: A display apparatus and a mobile terminal are provided. The display apparatus includes a display panel, N2 data drives, and a timing controller. Video data can be transmitted to a plurality of input video interfaces corresponding to the data drives in a time-sharing manner using one output video interface of the timing controller. Therefore, a timing controller with relatively low resolution can be matched with a display panel with relatively high resolution, thereby reducing overall costs of the display apparatus.

Abstract: A dielectric filter with a first radio frequency (RF) passband and a second RF passband, a radio unit, an antenna unit and a base station are disclosed. According to an embodiment, the dielectric filter (1) comprises a body (2) with a plurality of resonators (201, 202, 203, 204, 205) including a first resonator (202), a second resonator (204) and a common resonator (203). The common resonator (203) is coupled under its first resonance mode to the first resonator (202) to provide the first RF passband, and is coupled under its second resonance mode to the second resonator (204) to provide the second RF passband.

Abstract: An antenna unit, a radio unit, and a base station are disclosed. The antenna unit or the radio unit includes a plurality of filters, each having a respective radio frequency passband. At least one first filter is a CWG filter. The first filter is coupled to a second filter through a T-junction formed on an antenna board or a radio mother board.
