Disclosed are a mold assembly for making alkali metal wax packets, a method for preparing same, and a method for using same. The mold assembly comprises a silicon substrate (), the silicon substrate () comprising a mold isolator () at the edge of the silicon substrate () and a silicon substrate central portion (). The upper surface of the silicon substrate central portion () is indented to form a plurality of wax packet receiving cavities (). A cavity isolator () locates between adjacent wax packet receiving cavities (). A release sacrificial layer () is formed on the upper surface of the silicon substrate (), and a paraffin layer () is formed on the upper surface of the release sacrificial layer () away from the silicon substrate (). Cavities () for containing alkali metal are formed on a side of the paraffin layer () away from the release sacrificial layer (). The mold isolator () is provided with corrosion release holes (). The mold assembly can reliably and controllably achieve batch production of uniform alkali metal wax packet arrays and is completely compatible with MEMS and microelectronic processes, with simple processes that can be easily implemented and high operability. The wax packet mold assembly can be reused, such that wasting of raw materials can be avoided, and the cost of batch production can be effectively reduced.

The present application discloses a screen projecting method, an apparatus, a device and a storage medium. A specific implementation is: receiving a request for screen projecting from a terminal device, where the request for screen projecting includes indication information of content to be screen-projected; acquiring the content to be screen-projected according to the request for screen projecting; receiving a first initiating message of at least one screen projecting source from a target projecting device, and determining a target screen projecting source from the at least one screen projecting source; and sending the content to be screen-projected and an identifier of the target screen projecting source to the target projecting device, where the identifier of the target screen projecting source indicates to the target projecting device to display the content to be screen-projected through the target screen projecting source.
