Abstract: The present disclosure describes example service takeover methods, storage devices, and service takeover apparatuses. In one example method, when a communication fault occurs between two storage devices in a storage system, the two storage devices respectively obtain running statuses of the two storage devices. A running status can reflect current usage of one or more system resources of a particular storage device. Then, a delay duration is determined according to the running statuses, where the delay duration is a duration for which the storage device waits before sending an arbitration request to a quorum server. The two storage devices respectively send, after the delay duration, arbitration requests to the quorum server to request to take over a service. The quorum server then can select a storage device in a relatively better running status to take over a host service.

Abstract: A kind of plastic is provided. With a total of 100 parts by weight, the plastic includes the following components in parts by weight: 25 to 90 parts of matrix resin; 1 to 60 parts of laser reflecting agent; and 0 to 70 parts of inorganic filler, where the inorganic filler is capable of being chemically corroded. When the matrix resin includes a resin component capable of being chemically corroded, parts by weight of the inorganic filler are greater than or equal to 0 parts; or when the matrix resin is fully a resin component incapable of being chemically corroded, parts by weight of the inorganic filler are greater than 0 parts. For the plastic, a low roughness surface can be obtained through chemical roughening, to form a desirable coating binding surface, and help implement metallization.

Abstract: The present disclosure provides example electronic devices, auxiliary materials, and rear housing assemblies of an electronic device. One example electronic device includes a rear housing, a middle frame, a functional component, a speaker box, and an auxiliary material, where the rear housing covers the middle frame and forms a mounting cavity together with the middle frame. The functional component, the speaker box, and the auxiliary material are disposed in the mounting cavity. The functional component is adjacent to the speaker box. A rear acoustic cavity of the speaker box is connected to the mounting cavity. The auxiliary material is bonded between the rear housing and the functional component. The auxiliary material has a weak-adhesion surface and a strong-adhesion surface that are opposite to each other. The weak-adhesion surface is bonded to the functional component, and the strong-adhesion surface is bonded to the rear housing.

Abstract: Embodiments of the present invention provide a receiver and a wireless communications apparatus. The receiver includes: an attenuation circuit, configured to receive an input signal, and obtain a first signal according to the input signal; a low-noise amplification circuit, configured to receive the first signal, and obtain a second signal according to the first signal; an orthogonal down-frequency conversion circuit, configured to receive the second signal, and process the second signal to obtain an output signal; and a control circuit, configured to separately control the attenuation circuit and the low-noise amplification circuit according to power of an interference signal included in the output signal, so as to determine whether the attenuation circuit attenuates the input signal and whether the low-noise amplification circuit amplifies the first signal.
