Abstract: A granite stone powder phosphoric acid-based geopolymer and a preparation method thereof are provided. The granite stone powder phosphoric acid-based geopolymer is prepared from following raw materials in parts by weight: 35-70 parts of granite stone powder, 15-50 parts of metakaolin, 8-50 parts of fly ash, 8-30 parts of acid activation solution and 8-30 parts of solvent.

Abstract: A device and method for degassing an on-load tap-changer (OLTC) of a transformer for convenient on-site operation. The degassing device includes an OLTC. The OLTC is respectively connected with an oil suction pipe and an oil injection pipe. One end of the oil suction pipe extends to the inside bottom of the OLTC, and the other end of the oil suction pipe extends to the outside of the OLTC to connect with an oil suction and degassing device. One end of the oil injection pipe extends to an upper part inside the OLTC, and the other end of the oil injection pipe extends to the outside of the OLTC to connect with a vacuum oil injection device. The present disclosure has the advantages of convenient on-site operation, excellent degassing effect, simple structure and convenient installation, reduces degassing time and manpower and investment in maintenance, and improves degassing quality.

Abstract: A control method includes displaying a first interface, receiving first input of a user acting on a non-navigation button, displaying, in response to the first input, at least one of an artificial intelligence (AI) function entry interface and a scene service task interface that are corresponding to the non-navigation button, where the first interface includes a navigation bar, the navigation bar is provided with a navigation button and at least one non-navigation button, when the navigation button is triggered, an electronic device performs at least one of returning to a previous interface, jumping to a home interface, and invoking an interface of an application program accessed within a preset time up to a current moment, and when the at least one non-navigation button is triggered, the electronic device displays at least one of an AI function entry interface and a scene service task interface.

Abstract: Embodiments provide a voice interaction method and an apparatus, and relate to the field of terminal technologies. Common voice skill commands in a first application scenario may be determined based on the first application scenario and a historical voice skill usage record, and displayed in a display interface. This can implement scenario-based recommendation of voice skill commands, to cover as many application scenarios as possible. In this application, after being woken up, the voice assistant determines the first application scenario based on one or more information items. The voice assistant determines the common voice skill commands in the first application scenario based on the first application scenario and the historical voice skill usage record. The voice assistant displays the common voice skill commands in the first application scenario in the display interface.
