Abstract: This application provides techniques for generating customized prop images. The techniques comprise obtaining an initial prop image that comprises a target object, wherein the initial prop image comprises an initial image of any prop among at least one prop held by a target online streamer; obtaining an action file configured to specify an action of the target object; parsing the action file to determine a target action corresponding to the action file; and generating a customized prop image by updating a current action of the target object in the initial prop image to the target action, wherein the customized prop image corresponds to the target online streamer.

Abstract: An efficient and energy-saving blasting method based on a notched blast hole includes forming a cutting hole, an auxiliary hole, and a peripheral hole on a surface of an area to be blasted separately by means of a drilling apparatus. The cutting hole, the auxiliary hole, and the peripheral hole are formed on the surface of the blasting area separately, and notches with different numbers are formed on outer sides of the holes separately, such that in a blasting process, explosion energy of explosives can be transmitted along the notches, the explosion energy is guided, energy loss is reduced, blasting efficiency is improved, thus a range of a crushing area is reduced, a length of a main crack is increased, and a better blasting effect is achieved. Moreover, explosive energy is concentrated on the notch to initiate crack, so as to reduce an explosion smash area.

Abstract: Carrier gas connection devices (100, 402, 404, 406, 408) enable one to change the carrier gas provided to a gas chromatography channel. The carrier gas connection devices (100, 402, 404, 406, 408) comprise a channel adaptor (102, 202), a carrier block (104, 302), and a clamping system, and two or more channel adaptor positions. In each of the channel adaptor positions, a fluid-tight flow path for carrier gas out of the carrier block (104,302) into the channel adaptor (102, 202) is formed. Carrier gas distribution systems (400), gas chromatography instruments, and methods of changing a carrier gas supplied to a GC are also provided.
