Abstract: Provided an intermittent characteristic-based demand-side resource coordination control method and system. The method includes: receiving a control request, where the control request is used for requesting control of demand-side resources having an intermittent characteristic; determining a target total control quantity of demand-side resources; determining a coordination strategy of multiple demand-side resources and an action quantity of each of the multiple demand-side resources; and performing coordinated control on the multiple demand-side resources based on the target total control quantity of demand-side resources, the coordination strategy, and the action quantity of each of the multiple demand-side resources.

Abstract: A gearwheel body of structure-borne sound-reducing lightweight construction for electric drives in which shifting of the contact pattern of the wheel body under load is minimized in the case of a gearwheel body having a structured web extending substantially within a radial plane between a shaft seat and a toothed ring. The web has spiral structures that are thickened in a rib-like manner, and the spiral structures are aligned in such a way that their spiral shape meets at least the toothed ring at an oblique angle.

Abstract: The present disclosure relates to a die casting machine and a die casting method. The die casting machine used in cooperation with a mold (or die) having a die cavity configured to receive molten liquid and includes a plurality of injection mechanisms connected to the mold (or die). Each injection mechanism is provided with an injecting channel through which molten liquid is injected into the die cavity. The plurality of injecting channels are in connection with different positions of the die cavity.

Abstract: Provided are a ZmHsf21 gene, a protein encoded thereby and use thereof in plant breeding. Also provided are uses of the ZmHsf21 gene in increasing plant yield and/or improving plant disease-resistance, especially stalk rot.
