Abstract: A fracturing effect determination method for phase transition fracturing deep rock, comprising: obtaining initial data of a true triaxial rock of a fracture hole; fracturing true triaxial rock and obtaining acoustic emission information in the fracturing process; obtaining test data of the true triaxial rock after fracturing; inputting initial data and test data into a preset formula to generate test data; determining quantitative data of fracturing according to acoustic emission information and test data and determining the fracturing effect of true triaxial rock according to the quantitative data of fracturing. The method is implemented using a device comprising a carbon dioxide fracturing device, a true triaxial loading device, a fracturing starter, a storage tank, and a liquid filling device.

Abstract: The present invention relates to the field of solid-phase extraction, and particularly to a solid-phase extraction material, and a preparation method and use thereof. The preparation method includes prepolymerizing the monomers N-vinylpyrrolidone and divinylbenzene in the presence of a chain transfer agent, adding prepolymer dropwise to an emulsion of monodispersed seed microspheres, swelling, and reacting to prepare white spheres; and functionalizing the white spheres, to obtain the solid-phase extraction material. The solid-phase extraction material prepared by the reaction has good spherical morphology, large specific surface area, and high ion exchange capacity. The prepared solid-phase extraction material functions in the separation and enrichment of PPCPs by means of a variety of forces with a high extraction rate. The extraction rate is basically maintained between 85% and 105%, and acidic, alkaline, neutral and amphoteric substances is capable of being selectively separated.

Abstract: Embodiments of the present disclosure relate to methods and apparatuses for group message processing, system, and computer medium. In least one of the embodiments of the present disclosure, for a supersized group, i.e., a group with a number of members exceeding a predetermined number, a server creates a group inbox corresponding to the supersized group. After obtaining messages for the supersized group, instead of directly sending message events to the personal inboxes for respective members of the supersized group in a “write diffusion” mode, the message events are stored in a group inbox of the supersized group. So that when a user activates a client, the message events are obtained from the group inbox by the client, which achieves a “read diffusion” mode. As compared with the “write diffusion” mode, the “read diffusion” mode can reduce the resource consumption by the server, and improve the system stability.

Abstract: According to an embodiment of a power network device, the device includes a computer configured to estimate a plurality of parameters internal to a transformer, including estimating a turns ratio of the transformer. The computer performs the parameter estimation based on an equivalent circuit model of the transformer and current and voltage samples which correspond to current and voltage measurements taken at primary side and secondary side terminals of the transformer. The computer indicates when one or more of the estimated parameters deviates from a nominal value by more than a predetermined amount. The computer can be part of an intelligent electronic device configured to acquire analog or digital signals representing the primary side and secondary side current and voltage measurements, or located remotely from the intelligent electronic device e.g. in the control room or substation controller.
