Abstract: Embodiments of this specification provide batch scheduling-based application scheduling methods, apparatuses, and systems. In the batch scheduling-based application scheduling method, an application scheduling request is received from a client, where the application scheduling request includes description information used to indicate a chain invoking relationship between applications to be scheduled; the applications to be scheduled are grouped into at least one scheduling object group based on the chain invoking relationship, where applications to be scheduled that are located in the same scheduling object group have the same chain invoking relationship; and the applications to be scheduled are scheduled to a target node by using the scheduling object group as a unit.

Abstract: A method for controlling a surface glossiness of a metal workpiece includes: providing a metal workpiece; detecting the surface glossiness of the metal workpiece to obtain a first detection value; and, treating the metal workpiece by different processes according to different first detection values so that the surface glossiness of the metal workpiece satisfies the production requirements.

Abstract: The present invention provides a slow and controlled release polymeric sulfur fertilizer containing multiple nutrient elements. The slow and controlled release polymeric sulfur fertilizer is represented by the following formula, in which m=1-4, and n=100-210. The element sulfur in the slow and controlled release polymeric sulfur fertilizer according to embodiments of the present invention has very high utilization rate.
