The invention discloses a blast furnace smelting method for increasing the coal ratio, and relates to the technical field of ironmaking. The blast furnace smelting method comprises the following steps: alternately distributing coke and iron ore into a blast furnace to form an ore layer and coke alternate layer loading structure; a combustion improver and pulverized coal are fully and uniformly mixed to obtain a mixture, and the mixture is injected into a blast furnace to participate in chemical combustion reaction; wherein the combustion improver consists of the following components in percentage by mass: 20%-25% of barium oxide, 25%-35% of cerous oxide, 35%-40% of calcium oxide and 8%-12% of (C5H5) 2Fe; the addition amount of the combustion improver is 1-4% of the total amount of the injected pulverized coal in percentage by mass. A certain amount of the combustion improver is added into the mixed coal, the combustion improver and the pulverized coal are fully and uniformly mixed to obtain ...

The invention discloses a structural modal identification method based on an image phase in a video stream. The corresponding relation between principal component analysis and modal parameters is clarified; principal component analysis has the advantage of retaining high-spatial-resolution vibration information, and compared with a traditional method for obtaining the structure frequency according to a small number of discrete points, the error-tolerant rate of the algorithm is increased, and the frequency recognition precision is improved; a high-resolution single-mode extraction formula is theoretically deduced, and compared with mode shape extraction in a traditional frequency interval, the shape recognition precision is improved.

The invention discloses a temporary stand safety assessment method fusing a DS evidence theory and a Bayesian network model. The method comprises the following steps: 1) constructing a Bayesian network topological structure for temporary stand safety assessment; 2) establishing a recognition framework theta based on conditional probability values of each local structure of the Bayesian network, and calculating basic probability assignment; and 3) performing information fusion and linear processing on the basic probability assignment by using a DS evidence theory to obtain conditional probability information of each local structure in the Bayesian network topology structure. And 4) inputting the obtained conditional probability information into a Bayesian network model and carrying out reasoning analysis, thereby achieving the purpose of evaluating the safety of the temporary stand. According to the method, the DS evidence theory (Dempster-Shafer) is introduced into the calculation of the ...
