The present disclosure relates to systems, methods, and non-transitory computer-readable media for acquiring a virtual resource, including displaying an interactive interface of a second user in response to an access request of a first user for the interactive interface of the second user. A virtual resource state control is displayed on the interactive interface. A preview interface of a target multimedia resource posted by the second user is played in response to a trigger operation on the virtual resource state control by the first user in a case where the virtual resource state control indicates an available state. A preset quantity of virtual resources from virtual resources associated with the target multimedia resource is acquired in response to a trigger operation on the preview interface by the first user.

Method and device for acquiring virtual resource and storage medium

Embodiments of the present invention provide a method and an apparatus for eliminating interference among transmission channels of a transmitter. The method includes: generating a compensation parameter according to an output signal of an analog module on a transmission channel to be processed by the transmitter and an input signal of a digital module on each transmission channel among all transmission channels of the transmitter; generating a cancellation signal according to the compensation parameter and an input or output signal of a digital module on another transmission channel except for the transmission channel to be processed; and performing, according to the cancellation signal, interference elimination processing on the transmission channel to be processed. The method and apparatus according to the embodiments of the present invention avoid an increase of a transmitter product size, and improve an effect of eliminating interference among transmission channels.

Method and apparatus for eliminating interference among transmission channels of transmitter

A heat sink, including a heat sink body and a filling material. A through hole is disposed in a position, corresponding to a to-be-cooled electronic element, on the heat sink body. The to-be-cooled electronic element is mounted on a circuit board and located between the circuit board and the heat sink body. There is a gap between the to-be-cooled electronic element and the heat sink body. The gap is connected to the through hole. The filling material is injected into the through hole and fills the gap. The present invention further discloses a heat dissipation system having the heat sink. The heat sink resolves problems in the prior art that, a heat sink has low thermal conduction efficiency and it is difficult to control a filling volume of a thermally conductive material in a gap between a heat sink and a chip.

A metal optical grayscale mask includes a layer of metal film which is deposited on transparent substrate, and different transparency pattern which is formed by laser writing on the surface of the metal film. The pattern is continuous, in type of array or random pattern. The grayscale is within 3.0 OD-0.05 OD. The thickness of the metal film is 5-100 nm. A manufacturing method of the metal optical grayscale mask includes that the selected transparent substrate is rinsed by the general semiconductor rinse process, the metal film is deposited on the transparent substrate then different transparency pattern is formed by laser writing on the surface of the metal film. The pattern is continuous, in type of array or the random pattern. The grayscale mask is low in price, antistatic electricity performance is good, the resolution can surpass optical diffraction limit. The manufacturing method is simple. There is a wide band application for micro-optical components and large-scale production of micro-electro-mechanical systems.
