The invention belongs to the technical field of quantitative statistical distribution analysis of characteristic maps of microstructures and precipitated phases in metal materials, and relates to a full-field quantitative statistical distribution characterization method of precipitated phase particles in metal materials. The method includes the following steps: electrolytic corrosion of metal material samples, automatic collection of metallographic structure characteristic maps, automatic splicing and fusion of full-field metallographic structure characteristic maps, automatic identification and segmentation of precipitated phase particles, and large-scale full-field precipitation. Quantitative distribution characterization of phase particles. Through the establishment of a mathematical model, the present invention realizes the automatic splicing and fusion of metallographic structure feature maps in a wide range of full field of view in the characteristic area, automatic segmentation and identification of precipitated phase particles, and quickly obtains a full view of a large number of precipitated phases in a large range Quantitative statistical distribution characterization information such as field morphology, quantity, size and distribution, the method has the characteristics of accuracy, high efficiency, and large amount of quantitative distribution characterization information, which is more statistically representative than the conventional single-field image quantitative analysis.

The application relates to a detection device for fine particle migration detection of high-speed railway subgrade bed turbulence and mud discharge, which belongs to the field of railway slop and mud discharge detection. The mechanism loads the impact load into the sample filling chamber; the water supply system feeds liquid into the sample filling chamber along the vertical direction through the liquid inlet; There are multiple collection holes at intervals in the direction; the reversing switch assembly is arranged in the collection conduit to open and close the collection holes, so that only one of the collection holes in different positions is connected; through the above scheme, it is not only possible to detect the vertical It can also detect the migration of mud and mud in the lateral direction, and can reflect the influence of the boundary on mud and mud during the test from the side, so as to ensure that the results of fine particle migration of mud and mud in the test are relatively accurate.

The invention relates to a simulation method for evaluating the deep migration characteristics of polymer microspheres in porous media, which includes: making a long core model; testing the resistance coefficient and residual resistance of polymer microspheres at different migration depths in the long core model coefficient; use the matching coefficient to characterize the matching relationship between polymer microspheres and core pores; draw the relationship curve between polymer microsphere injection pressure, resistance coefficient and residual resistance coefficient and displacement depth, and find the maximum injection pressure, resistance coefficient and residual resistance coefficient value of the displacement depth, at which the polymer microspheres can achieve the best fluidity control and retention capacity; draw the relationship curve between the particle size and matching coefficient of the polymer microspheres in the production fluid and the displacement depth, and determine the polymer microspheres at Particle size range and matching coefficient range in different migration periods. The invention simulates the long-distance migration of polymer microspheres in porous media, and facilitates water plugging and profile control personnel to select a suitable type of polymer microspheres according to the depth of profile control.
