Abstract: The present invention relates to the field of printed circuit heat exchangers, and in particular, to a modular square-circular composite channel printed circuit heat exchanger. The modular square-circular composite channel printed circuit heat exchanger comprises a shell, wherein the shell is divided into an inlet diverter section, a first parallel heat exchange section, a core heat exchange section, a second parallel heat exchange section, and an outlet combiner section from left to right, a plurality of square fin channels and circular micro-channels are uniformly arranged in the shell along a length direction of the shell. According to the present invention, a ratio of an average thermal resistance of a hot side to an average thermal resistance of a cold side is close to 1, which ensures the heat exchange efficiency while taking into the account structure safety and prevents the local over-temperature.

Abstract: The present disclosure provides a blending method of high-quality and dual-purpose flour for bread and noodles, belonging to the technical field of flour processing. The method includes: selecting flour of a high-quality and dual-purpose wheat variety for bread and noodles as a high-quality basic flour for blending; according to a large gradient experimental design, selecting a gradient range ratio with a sedimentation value ?46.0 mL and a dough development time ?9.6 min, followed by subdividing for small gradient experiments; selecting a ratio with flour sedimentation value and dough development time that reach an ideal value to blend a large amount of flour; and making bread and noodles for scoring, followed by determining a blending ratio if a scoring result reaches an ideal value.

Abstract: Disclosed are a method of performing video call and a display device. The display device includes: a camera; a display, configured to present a window for a counterpart and/or a local window; and a processor, configured to: receive a push message sent from a server, wherein the push message is sent after the server receives a video call request sent from the mobile terminal; automatically establish a call process, and control the display to present the window for the counterpart and not to present the local window in response to the push message when the mobile terminal is authorized by the display device; and reject the video call request in response to the push message when the mobile terminal is not authorized by the display device.

Abstract: Various aspects of the present disclosure are directed to a communication module for data transmission between at least one hardware component which is integrated into an internal network of a technical system and a back-end computer system which is connected to a packet-switched data network. In one example embodiment, a communication module is disclosed including a point-to-point connection, a device-proximal gateway is configured and arranged to provide a data transmission interface between the point-to-point connection and the internal network, and a network-proximal gateway connected to the device-proximal gateway via the point-to-point connection without intermediate stations, the network-proximal gateway configured and arranged to provide a data transmission interface between the packet-switched data network and the point-to-point connection.

Abstract: An interactive music audition method, apparatus and terminal are provided. The method includes: generating audition inquiry information according to audition requirement information, wherein the audition inquiry information includes a plurality of audition music options associated with the audition requirement information; generating a plurality of audition inquiry voices corresponding to the respective audition music options based on the audition inquiry information, and playing the generated audition inquiry voices; acquiring music selection information for the generated audition inquiry voices; and playing audition music according to the music selection information. Not only the interaction experience between a user and a smart device is improved, but also the accuracy of mining a user's interest is increased.
