Provided are a method for tracking carbon flow of a power system, a device and a medium. The method includes: acquiring related data of carbon flow tracking, where the related data include an injected active power sum column matrix of generator sets of all substations to be tracked, an injected carbon flow rate sum column matrix of generator sets of all substations to be tracked, an output power distribution matrix of a branch formed between substations to be tracked, and a power flow proportion distribution matrix of the branch formed between substations to be tracked; acquiring a carbon potential matrix Eof each substation to be tracked; and acquiring a carbon flow rate of each substation to be tracked, a carbon flow rate of the branch, and a carbon flow rate of an output load on the basis of the carbon potential matrix of each substation to be tracked.

Method for tracking carbon flow of power system, device and medium

An electronic device includes a base, a connection device, a body, an antenna assembly, and a shield member. The body rotates to a first operating state and a second operating state relative to the base through the connection device. The shield member moves in the base to a shielding state and a non-overlapping state. When the body is in the first operating state, the body is not overlapping with the antenna assembly in a first direction, the shield member is in the non-overlapping state, and the shield member is not overlapping with the antenna assembly in the first direction. When the body is in the second operating state, the body overlaps at least a portion of the antenna assembly in the first direction, the shield member is in the shielding state, and the shield member shields between the antenna assembly and the body.

Electronic device

Embodiments of the present disclosure provide an electronic device and an antenna. The antenna for includes a first component configured for high frequency feed; a second component configured for low frequency feed; a third component configured for high frequency signal transmission; and a fourth component configured for low frequency signal transmission. The first component is coupling a high frequency signal to the third component, and the second component is coupling a low frequency signal to the fourth component.

Electronic device and antenna

An electronic device is provided. The electronic device includes a housing, an audio output device, and a radio frequency (RF) device. The housing includes at least a conductive first portion made of a conductive material, and the conductive first portion has an opening. The audio output device is disposed in the housing and corresponding to the opening to output an audio, a space exists between the audio output device and the housing, and the audio passes through the opening to be perceived by a listener outside the housing. The radio frequency (RF) device is disposed in the space for radiating a wireless signal under a coupling effect of the opening of the conductive first portion of the housing.

Disclosed is a single notch filter, comprising a dielectric layer, a first metal layer and a second metal layer, wherein the first metal layer and the second metal layer are arranged onto two opposite surfaces of the dielectric layer, the first metal layer comprises a metal microstrip patch, the second metal layer comprises a coplanar waveguide plate and a metal grounding plate, and a fractal defected ground body of the coplanar waveguide plate is coupled with the metal microstrip patch based on the dielectric layer. Other embodiments are described and claimed.
