Abstract: A pipeline integrated module includes: a first plate-like component having a first groove that has a first stamped chamfer at an opening of the first groove, a second plate-like component having a second groove that has a second stamped chamfer at an opening of the second groove, and a sandwich layer disposed between and connected to the first plate-like component and the second plate-like component. The first plate-like component and the second plate-like component cover each other. The second groove and the first groove correspond to each other and together enclose a cavity. The cavity has a gap between the first stamped chamfer and the second stamped chamfer. The sandwich layer has an end portion facing towards the cavity and located within the gap.

Abstract: An air conditioner outdoor unit and an air conditioner are provided. The air conditioner outdoor unit includes: a cabinet, which is provided with an air inlet and an air outlet; a refrigerant circulation device, which is arranged inside the cabinet, and partial region of which interferes with an airflow path between the air inlet and the air outlet; and a fan, which is provided inside the cabinet and arranged opposite to the air outlet. In a direction of a rotational axis of the fan, the partial region has a projection region on the fan. The fan is provided with at least one fan blade. An installation angle of the fan blade at any elementary stage within the projection region is larger than an installation angle of the fan blade at an elementary stage outside the projection region.

Abstract: The present disclosure provides a data processing method and device, the method includes: acquiring exercise data of a user in a preset time period and a physical parameter preset by the user, wherein the exercise data comprises exercise data of a head, a hand and a leg of the user; and inputting the exercise data and the physical parameter into a pre-trained energy determination model for processing to obtain energy consumed by the user in the preset time period.

Abstract: An application of farnesene in preparing a plant-derived urease inhibitor is provided. The compound can effectively inhibit activities of Canavalia ensiformis urease and soil urease, and has an effect that is equivalent to that of commercial urease inhibitor acetohydroxamic acid. The urease inhibitor in the present disclosure, derived from plants, has “pollution-free” characteristics of natural products, high biological safety, simple and stable chemical structure and remarkable urease inhibition effect, can solve the problems of conventional chemically-synthesized urease inhibitor such as high toxicity, easy degradation and poor stability, also provides a new concept for creating a biological ecological technology for efficiently inhibiting the rapid hydrolysis of urea in farmland and increasing the utilization rate of urea nitrogen fertilizer, and has good application value and development prospect.
