Abstract: A measurement method, a terminal and a network side device are provided. The measurement method performed by a terminal includes: in a non-connected state, triggering an automatic measurement when a predetermined condition is met. In an embodiment of present disclosure, it is agreed that the terminal in a non-connected state triggers the automatic measurement when the predetermined condition has been met, so the terminal immediately reports an indication indicating that there is an available measurement result, or report an available measurement result, to the network side device when entering a connected state.

Abstract: The present disclosure provides an apparatus and a method for hydrate-based wastewater treatment and cold storage. The apparatus for hydrate-based wastewater treatment and cold storage includes a water chilling unit, a hydrate-based cold storage tank, an airflow disturbance device, a water layer positioning system, a spraying system, a suction filtration system, a heat exchange system, and a system monitoring device. The water chilling unit provides a secondary refrigerant at a low temperature. The secondary refrigerant flows through an evaporator coil in the hydrate-based cold storage tank for heat exchange. The airflow disturbance device induces hydrate nucleation. The water layer positioning system positions a contact surface between a water layer and a hydrate former after hydrate decomposition to facilitate drawing and separation of the treated upper water layer. The spraying system and the suction filtration system enhance the solid-liquid separation efficiency to improve the removal rate of pollutants.

Abstract: This invention relates to a surfactant composition, production and use thereof in tertiary oil recovery. The present surfactant composition comprises a cationic surfactant and an anionic-nonionic surfactant, and exhibits significantly improved interfacial activity and stability as compared with the prior art. With the present surfactant composition, a flooding fluid composition for tertiary oil recovery with improved oil displacement efficiency and oil washing capability as compared with the prior art could be produced.

Abstract: A terminal device sends first information to a cloud device, where the first information indicates a posture and a location of the terminal device at a first moment. Then, the terminal device receives information about a first field of view image from the cloud device, where the first field of view image is a field of view image corresponding to the posture and the location of the terminal device at the first moment. The terminal device displays an image within a field of view range of the terminal device at a second moment based on the information about the first field of view image and a posture change and a location change of the terminal device from the first moment to the second moment.

Abstract: A method and an apparatus for tracking a clock source are disclosed. The method includes determining a best clock source to be tracked by a device according to a best clock source tracked by a slave candidate port in the device and distributing the best clock source tracked by the device through a master candidate port in a master state. Through the embodiments of the present disclosure, the clock source selection of the device converges quickly. Moreover, because the slave candidate port is determined according to the network planning, the planning of the transport network is observed.

Abstract: A method of clock transmission between networks and an apparatus of clock transmission are disclosed, in which a second group of information corresponding to a clock transferred by a first network equipment based on a first protocol, and the second group of information corresponding to a clock transferred by a second network equipment based on a second protocol are acquired, and a source selection is performed in a united way by adopting a source selection manner based on the second protocol according to the second group of information. Therefore, the equipment in different types of networks can conveniently select a clock with a higher class from clocks transferred based on different protocols, so as to realize a normalization management on the clocks transferred based on different protocols.
