Abstract: A composition and use thereof. The composition comprises an active component a and an active component b; the active component a is a compound as shown in general formula A; and the active component b is at least one of compounds which have insecticidal, acaricidal or bactericidal activity and are different from the compound as shown in general formula A. The composition has the advantages of synergistic effect and expanding prevention and treatment spectrum, and can be used for preventing and treating various pests, particularly mite damage, and plant diseases caused by various fungi, bacteria, nematodes and viruses.

Abstract: A safety belt guiding apparatus and a child car seat are disclosed, the latter includes a seat shell with a holder and thereon a backrest section and a seat section movably disposed. The seat section and the backrest section are pivoted to each other thereby allowing the seat shell at least two using positions. A safety belt guiding apparatus assembled to the holder includes a safety belt director and a linking assembly with one end of it linked to the backrest section or the seat section and another to the safety belt director. During a switch among using positions, the backrest section or the seat section selectively drives the safety belt director to pop out of or retract to the holder, where a safety belt selectively passes through the safety belt director to fasten the seat shell, alone or base-assembled, to a car seat, thereby providing versatility.

Abstract: A sulfone polymer composition and preparation method thereof, and thermoplastic molding composition therefrom, comprising: (A) at least one aromatic sulfone polymer; (B) one compound of 4,4?-dichlorodiphenyl sulfone; wherein, based on the total weight of the sulfone polymer composition, 4,4?-dichlorodiphenyl sulfone weight content is less than 600 ppm. In the preparation method, tetramethylene sulfone is used as a solvent, 4,4?-dichlorodiphenyl sulfone and 4,4?-Dihydroxydiphenyl sulfone or 4,4?-dihydroxy biphenyl are used as reactive monomers, while the mixed salt of sodium carbonate and potassium carbonate is used as salt-forming agent, the composition may be obtained by polymerization with solution polymerization techniques; wherein the molar ratio of the said potassium carbonate and sodium carbonate is 0.1: 100-5: 100.

Abstract: Disclosed are a video interaction method, a terminal, a server, and a system. The method includes: receiving a video microphone-connection invitation transmitted by a first terminal, the video microphone-connection invitation carrying at least one terminal identifier; transmitting the video microphone-connection invitation to a second terminal corresponding to the terminal identifier; after receiving an accept response returned by the second terminal, granting the second terminal a video publishing right, and establishing a microphone-connection session connection between the first terminal and the second terminal; receiving video data published by the first terminal and video data published by the second terminal, wherein the video data published by the first terminal and the video data published by the second terminal are displayed on the same window interface respectively in the first terminal and the second terminal.

Abstract: A rotatable tray is installed on a child seat for accommodating a container, and the rotatable tray includes a platform, a fixing base, a positioning base, a resilient component and a supporting base. The platform includes a communicating chamber, and the fixing base is fixed in the communicating chamber. The positioning base includes a first engaging portion, and the positioning base is slidably disposed in the communicating chamber. The resilient component is disposed between the fixing base and the positioning base. The supporting base is connected to the platform, an engaging base protrudes from an end of the supporting base, and a second engaging portion is disposed on the supporting base. The engaging base is pivoted in the communicating chamber so that the platform can rotate relative to the supporting base. The resilient component drives the first engaging portion to selectively engage with the second engaging portion.

Abstract: A brake mechanism for a stroller includes an axle, a wheel and at least one brake fixing seat disposed at an inner side of the wheel. The brake fixing seat includes a brake assembly and a fixing seat. The brake assembly includes a pedal assembly and a brake member. The brake member has at least one abutting portion and at least one brake arm. The brake assembly includes a pushing member for pushing the abutting portion. A brake hub is disposed at the inner side of the wheel. A plurality of recesses is formed on the brake hub and arranged compactly. The axle passes through the pedal assembly, the brake member, and the fixing seat. The pedal assembly is used to drive the pushing member to push the abutting portion and the brake member moves toward the brake hub until the brake arm extends into the recesses.
