This application discloses a method and apparatus for constructing a multi-scale adaptive gating MambaPlus network, belonging to the field of artificial intelligence and machine learning technology. The method includes: initializing the network configuration and constructing the basic structure; preprocessing the input data to generate a standard dataset; mapping the input data to the hidden space via an input mapping layer, and extracting backbone features from the Mamba backbone; constructing at least two parallel scale branches in the hidden space to obtain a multi-scale feature set; inputting the backbone features and multi-scale features into an adaptive gating module, dynamically allocating weights and adaptively fusing them through a hierarchical gating mechanism to generate fused features; further enhancing the features through cross-scale attention and feedforward enhancement, and then superimposing the residuals to generate the final discriminative features; finally, completing category prediction and model training evaluation. This application, while retaining the advantages of Mamba's long-range dependency modeling, addresses the problems of insufficient utilization of multi-scale information, poor adaptive feature fusion, and low robustness in complex scenarios.

This invention discloses a composite admixture and its preparation method, as well as a method for preparing concrete pipe piles. The composite admixture comprises submicron-sized metakaolin, ultrafine quartz sand powder, slag powder, calcium formate, sulfate activator, water-retaining and toughening component, auxiliary setting regulator component, and superplasticizer; wherein, by weight percentage, the submicron-sized metakaolin is 12%-18%, the ultrafine quartz sand powder is 22%-30%, the slag powder is 35%-45%, the calcium formate is 2.5%-4.0%, the sulfate activator is 7%-11%, and the water-retaining and toughening component is 2.0%-4.0%; the median particle size D50 of the submicron-sized metakaolin is 1.0μm-3.0μm, and the specific surface area is ≥1200m² / kg; the water-retaining and toughening component is a mixture of redispersible latex powder and cellulose ether in a mass ratio of (2:1)-(1:1). This invention, through multi-component synergy, significantly improves the early strength, later strength, durability, and crack resistance of concrete under low-temperature steam curing conditions of 40℃-60℃, which can simultaneously meet the differentiated performance requirements of PHC piles and large-diameter pipe piles, and greatly reduce production energy consumption.

This invention discloses a flotation separation method for collecting galena and inhibiting sphalerite and pyrite, achieving efficient separation of galena from sphalerite and pyrite in a low-alkaline pulp environment, belonging to the field of mineral beneficiation technology. This invention uses N-hydroxyethylethylenediaminetriacetic acid as an inhibitor of sphalerite and pyrite at a low alkalinity of pH 7.5-9.5, and one or two of sodium diethyldithiocarbamate, sodium ethyl xanthate, and xylenol dithiophosphate as collectors for galena. Under low dosage conditions, it achieves simultaneous inhibition of sphalerite and pyrite and effective collection of galena, offering advantages of high efficiency, simple process, economy, and environmental friendliness. It is particularly suitable for silver-bearing, high-sulfur, low-grade lead-zinc ores and has broad application prospects.
