Abstract: An interaction method and apparatus and an electronic device. The method comprises: displaying a first application interface, wherein the first application interface comprises an interface of a first application; and creating a second application account in the first application interface, wherein the second application account is used for logging in a second application. Therefore, a new interaction mode is provided.

Abstract: A filecoin cluster data transmission method and system based on RDMA, including: providing a RDMA interface; receiving and encapsulating sector data by a first node, invoking the RDMA interface to transmit the sector data, serially transmitting the sector data to a next encapsulation node; when receiving the sector data from a previous node, invoking the RDMA interface to directly transmit the sector data to a user mode memory of the node for encapsulation; invoking the RDMA interface to serially transmit the sector data back to the HCA card, and transmitting the sector data to a next node; receiving, by a last node, the sector data, invoking the RDMA interface to directly transmit the sector data to the user mode memory of the last node; invoking the RDMA interface to serially transmit the sector data back to the HCA card of the last node, and transmitting the sector data to distributed storage.

Abstract: A phase shifter includes a radio frequency input transmission line, a radio frequency output transmission line, and a first branch and a second branch coupled in parallel between the radio frequency input transmission line and the radio frequency output transmission line, the first branch includes first switch components and first transmission lines coupled in series, and the second branch includes a second transmission line including a first terminal coupled to the radio frequency input transmission line and a second terminal, a third transmission line including a third terminal coupled to the second terminal and a fourth terminal coupled to the radio frequency output transmission line, second switch components, where one terminal of each of the second switch components is coupled to a connection node of the second transmission line and the third transmission line, and the other terminal is coupled to a corresponding grounding component.
