Abstract: An invert emulsion having double particle size distribution, the invert emulsion having a particle size distribution of latex particles between 20 nm and 70 nm and between 100 nm and 500 nm in the same invert emulsion system. A preparation method for an invert emulsion comprises: forming an emulsion A and an emulsion B having different particle sizes by controlling an emulsifier system and an emulsification means, and preparing in one step an invert emulsion the particle size of which has bimodal distribution by means of a three-stage polymerization reaction between the emulsion A and the emulsion B in the same system. The invert emulsion is used as a water treatment flocculant, a sludge dewatering agent and a papermaking auxiliary agent, and in particular, the sludge dewatering agent fabricated from the invert emulsion is used for dewatering sludge.

Abstract: A preparation method for a CDK4/6 inhibitor for a compound of formula (I): 5-fluoro-4-(3-isopropyl-2-methyl-2H-indazol-5-yl)-N-(5-(piperazin-1-yl)pyrazol-2-yl)pyrimidine-2-amine. The preparation method has cheap and readily available starting materials and reagents, greatly simplified total reaction steps, shortened reaction time, improved total yield and a high purity of the key intermediate and final product, being suitable for industrial production.

Abstract: The present disclosure provides a control method and a control apparatus for a communication device, a communication system, and a storage medium. The control method for a communication device includes periodically outputting, a first level signal and a second level signal to the communication bus, and the second communication device establishes a data connection with the first communication device based on that the level signal on the communication bus is the first level signal, and the second communication device establishes a power supply connection with the first communication device based on that the level signal on the communication bus is the second level signal. Since the data connection and the power supply connection do not appear at the same time, the communication bus using the above-mentioned control method does not need to set an inductance compared to the traditional Home Bus.

Abstract: The present application provides a welding assembly and a battery module. The welding assembly includes: a first weldment; and a second weldment, welded and fixed with the first weldment to form a welding seam; where, at least one side of the welding seam is provided with an exhaust channel; and the exhaust channel is located between the first weldment and the second weldment. In the present application, an exhaust gas generated during welding can be discharged from the exhaust channel to prevent it from entering the welding seam to reduce the strength of the welding seam.

Abstract: An impeller tube-type nozzle for a gas turbine, with an inlet section, a retraction section and an outlet section. The inlet section is a section of annular channel, the retraction section comprises multiple gas flow channels separated by multiple blades, each gas flow channel is encircled by an outer peripheral wall face, an inner peripheral wall face, a suction face of one of two adjacent blades and a pressure face of the other of the two adjacent blades, and inlets of the gas flow channels have a fan-shaped cross section. For each gas flow channel, along the direction of gas flow from the inlet of the gas flow channel to the outlet the fan-shaped cross section gradually smoothly transitions into a circular cross section.
