Abstract: The present disclosure provides a preparation method of a titanium implant with a surface coating in a crater-like porous shape. A titanium substrate is subjected to polishing, cleaning, and first drying in sequence to obtain a pretreated titanium substrate. This step eliminates an influence of roughness and surface impurities of the titanium substrate on roughness and a structure of a coating formed on a surface of the titanium substrate after micro-arc oxidation, so as to obtain a titanium implant with a specific structure and a desirable biological performance. The micro-arc oxidation is conducted using the pretreated titanium substrate as an anode and iron as a cathode in an electrolyte containing sodium phosphate. In this step, a micro-arc oxidation coating is formed on the surface of the titanium substrate to obtain the titanium implant with a surface coating in a crater-like porous shape.

Abstract: Provided is a method for a dynamic state estimation of a natural gas network considering dynamic characteristics of natural gas pipelines. The method can obtain a result of the dynamic state estimation of the natural gas network by establishing an objective function of the dynamic state estimation of the natural gas network, a state quantity constraint of a compressor, a state quantity constraint of the natural gas pipeline and a topological constraint of the natural gas network, and using a Lagrange method or an interior point method to solve a state estimation model of the natural gas network. The method takes the topological constraint of the natural gas network into consideration, and employs a pipeline pressure constraint in a frequency domain to implement linearization of the pipeline pressure constraint, thereby obtain a real-time, reliable, consistent and complete dynamic operating state of the natural gas network.
