Abstract: A plasma-facing component of a fusion reactor divertor, including an inner target transition support and a dome transition support which are integrated into an inner target-dome transition support. The inner target-dome transition support and an outer horizontal target transition support are each prepared from two materials. The channel connection inside the inner target-dome transition support and the outer horizontal target transition support is realized through an S-shaped flow channel and a collector box. In V-shaped regions of inner and outer targets, a plasma-facing unit is connected to the collector box in the transition support via a bending tube, and is communicated with a coolant flowing through horizontal and vertical targets through an intermediate flow channel in the transition block. A method of preparing the plasma-facing component is further provided.

Abstract: A method, apparatus, and terminal for transmitting a message in a multiplayer game, and a medium are provided, belonging to the field of human-machine interaction. The method includes: displaying a first user interface of the multiplayer game, the multiplayer game providing a virtual environment for at least two teams of virtual characters to conduct an online battle; displaying a warning transmitting control in a predetermined region on the first user interface in response to that an event associated with a virtual character in the virtual environment satisfies a warning condition, the warning transmitting control being configured to transmit a warning message corresponding to the event; and transmitting the warning message to a second terminal in response to a transmitting operation on the warning message, the first account and the second account having a teammate relationship.
