Abstract: A composite solution for enhancing induced disease resistance of lentinan (LNT) to a plant, a preparation method of the composite solution, and a method for enhancing induced disease resistance of LNT to a plant are provided. The composite solution for enhancing induced disease resistance of LNT to a plant includes: an LNT-containing solution and an SPc-containing solution, where SPc is a dendritic macromolecule functionalized by an amino functional group, and has a structural formula shown in formula I, where n=1 to 100. An LNT/SPc complex is produced in the composite solution. SPc spontaneously combines with LNT through hydrogen bonding, such that an agglomerate structure formed by LNT in an aqueous solution is broken and reduced to a nano-scale particle size, and a spherical particle is produced, which can significantly reduce a contact angle of the LNT aqueous solution, and promote the distribution and diffusion of LNT.

Abstract: The present application discloses a Hive table scanning method, device, computer apparatus and storage medium, wherein the method includes: acquiring an update cycle of a Hive table; determining an update cycle level corresponding to the update cycle; determining a target scanning rule corresponding to the update cycle according to a preset correspondence table between the update cycle level and a preset scanning rule; and performing scan statistics to the Hive table according to the target scanning rule.

Abstract: A plastic housing comprises a top wall, a plurality of sidewalls extending from the top wall, each sidewall having a first end adjoining the top wall and an opposite second end, the sidewalls cooperatively defining an opening at the second ends thereof; the top wall has a uniform thickness, and a thickness of each of the sidewalls gradually decreases from the first end to the second end. Because of the shrinkage rate of the second ends of the sidewalls is much greater than the first ends of the sidewalls, the thickness of each sidewall is decreasing from the first end to the second end, therefore, the shrinkage deformation of the sidewalls can be even with the gradient thickness. The warping of the sidewalls is alleviated or is avoided.
