Abstract: The present disclosure relates to cross-domain fault analysis methods and systems. According to the methods and the systems, whether a first single-domain network fault and a second single-domain network fault are caused by a same fault is determined based on correlation analysis on the first single-domain network fault and the second single-domain network fault in time dimension and service dimension.

Abstract: An MPCVD device capable of realizing effective doping, comprises a reaction chamber and a gas input structure, wherein the gas input structure includes a first pipeline and a second pipeline for reaction gas, a first gas distributor, connected with the first pipeline, uniformly transports gas as a first reactant into the reaction chamber through a gas outlet of the first pipeline located near the top of the reaction chamber, the second pipeline uniformly inputs a doped reaction gas to a surface of a substrate through a second gas distributor with circular shape, a height of the gas transport ring connected with the second pipeline is substantially the same as that of a support for the substrate, and the gas transport ring can be concentrically placed at a center position inside the support, or the gas transport ring can also be concentrically placed outside the support.

Abstract: The disclosure provides a preparation method of a hollow porous spherical particle artificial bone. The method comprises: (1) uniformly mixing bioceramic powder, bioglass powder and an excipient to obtain a solid-phase mixture, then adding binder solution to the solid-phase mixture, and uniformly mixing to obtain a plastic wet material; (2) loading a plastic wet material into an extrusion device of an extrusion rounder to be extruded by the orifice plate of the extrusion device to form a strip-shaped material; (3) putting the strip-shaped material into the spheronization device, cutting, and then spheronizing to form spherical particles; and (4) placing the spherical particles into a furnace, debinding, removing the excipient and the binder, and then sintering at 750-1550° C.
