Abstract: The present invention pertains to the field of oilfield stimulation technologies for oil and gas field development, in particular to an instant soluble temperature and salt resistant polyacrylamide and the preparation method and application thereof, and the polyacrylamide is modified by adding rigid temperature and salt resistant monomer containing benzene ring and cationic fluorinated hydrophobic monomer on the basis of acrylamide monomer and sodium acrylate monomer, and then polymerized to obtain instant soluble temperature and salt resistant polyacrylamide. The temperature and salt resistant monomer containing benzene ring can improve the thermal stability and temperature and salt resistance of polyacrylamide, while the long-chain cationic fluorinated hydrophobic monomer can enhance the hydrophobicity of polymer. The comprehensive properties of polymer is improved by appropriate intermolecular association.

Abstract: The present disclosure relates to a method for analyzing a geological body with the help of physical and chemical properties thereof, and in particular, to a method for identifying an exudative sandstone uranium deposit. With the method for identifying an exudative sandstone uranium deposit according to the embodiments of the present disclosure, an exudative sandstone uranium deposit formed by an exudation metallogenesis may be systematically identified, so as to guide prediction and prospecting evaluation of a uranium deposit in red variegated sandstone formations of a sedimentary basin, avoid ore dislocation and ore leakage, open up new prospecting positions and spaces, and break through new uranium resources.

Abstract: A probe mounting structure and a wafer-level reliability test system are provided. The probe mounting structure includes a probe mounting plate. The probe mounting plate is provided with mounting holes penetrating through a thickness direction of the probe mounting plate. A volume of each mounting hole is smaller than a preset value and is used to install a corresponding probe. Two ends of each probe are respectively connected to a corresponding first pad on a circuit board and a corresponding die of a wafer under test. Two sides of the probe mounting plate are in contact with the test circuit board and the wafer under test respectively, such that each of the mounting holes forms a sealed chamber. The mounting holes are filled with high-pressure gas to ensure that the wafer under test does not spark during high-voltage testing.

Abstract: Embodiments of the present disclosure provide an apparatus and a method for generating a circuit clock signal. The apparatus comprises: a clock buffer configured to buffer an original clock signal to obtain a buffered clock signal; a clock delay unit configured to delay the original clock signal to obtain a plurality of delayed clock signals, the plurality of delayed clock signals being respectively delayed by different amounts of time relative to the original clock signal; a broadened clock generator configured to generate a broadened clock signal based on the original clock signal and the plurality of delayed clock signals, the frequency of the broadened clock signal being lower than that of the original clock signal; and a clock selector configured to select one of the buffered clock signal and the broadened clock signal as the circuit clock signal based on a selection signal.

Abstract: Various aspects of the present disclosure generally relate to wireless communication. In some aspects, a user equipment (UE) may disconnect from a first radio access technology (RAT) service, independent of signaling from the first RAT service, after sensing that the UE has entered a coverage hole. The UE may use a connection to a second RAT service while in the coverage hole in association with disconnecting from the first RAT service. The UE may disconnect from the second RAT service, independent of signaling from the second RAT service, after sensing that the UE has exited the coverage hole and before expiration of a radio link failure (RLF) timer for the second RAT service. The UE may reconnect to the first RAT service before expiration of an RLF timer for the first RAT service. Numerous other aspects are described.

Abstract: Machine-based verification is minimized by presenting a web page to a user that includes a number of objects in a verification image, and then instructing the user to click on the objects in the verification image in a particular order. The user selected order is then compared to a known correct order, and verification is complete when the user selected order matches the known correct order.

Abstract: A dual-position loop control method and system of a turntable are based on a harmonic speed reduction mechanism. The system and the method use feedbacks from two positions with the help of a first position sensor mounted on a shaft of a motor and a second position sensor mounted on an output end of a harmonic speed reducer respectively. The response is fast at the position of the shaft of the motor, and the second position sensor at the output end of the harmonic speed reducer can directly measure the position of a harmonic output end. Therefore, the influence of nonlinearity factors on the control system is reduced.
