“…The PSO algorithm is derived from this model and is used to solve optimization problems. Moreover, people often make decisions based on their own experience and the experience of others, which forms the basic concept of PSO (Barma et al 2018). The same particle swarm algorithm has the same principles as other evolutionary algorithms, and some people think that it is an evolutionary algorithm, based on the environment suitable for individuals in the group to move to the appropriate field (Catcheside and Ralph 2002).…”

This paper uses the function of neural network-based nonlinear mapping and particle group optimization algorithm to optimize the system, and then uses the particle group optimization algorithm of inertia weight, so as to achieve the goal of optimizing the weight of neural network training. By choosing to encode the geological parameters of the coastline with mpeg-4 and obtain the relevant data, the relevant data of the beach motion image can be obtained, so that the simulation experiment can be carried out. This paper introduces the process of establishing a multi-modal pore size distribution fitting model based on probability density function, and conducts an experimental analysis on the geological parameters and pore structure of two typical shale storage layer samples in China. Finally, the multi-peak opening distribution fitting model and the pore size distribution are obtained through quantitative fitting curves, and the geological parameters of the marine continental shale that affect the pore size distribution are investigated, and the pore size distribution of the shale and the geology of the shale are investigated. In-depth parameter analysis is to explore the thermal maturity of organic matter, and the relationship between its content and mineral composition. In addition, the coastal image simulation is researched focusing on the characteristics of coastal beach recreational sports, the problems existing in the development process, and future development countermeasures. Finally, it is pointed out that the future development trend of coastal beach leisure sports, through the integration of local leisure sports-related characteristics and professional development, so as to achieve the implantation of culture in sports, and the organic combination of the two promotes the economic and ecological environment.

“…Besides, the difference in ash removal by the various acids could be explained by the ability of the acids to remove different inorganic components. According to the study by Barma et al , 26 HCl could dissolve impurities in coal by converting them into soluble metal salts. Steel et al 27 reported that HCl was able to remove Ca, Fe, Mg, Na and some of Al, K and Ti, which were minerals in coal.…”

“…There are three types of cleaning fluids prepared, i.e., 75% (v/v) alcohol (marked as #1 for simplicity), glass cleaning fluid (the main proportion is 10 wt.% C4 alkyl polyoxyethylene ether, 2 wt.% C12 sodium alkylbenzene sulfonate, 5% wt.% sodium toluene sulfonate, 3 wt.% ethanol, and 80 wt.% water) mixed with 6 wt.% NaHCO 3 solution (the volume ratio of the two is 1 : 1; #2), and glass cleaning fluid (#3). The glass samples were ultrasonically cleaned in different cleaning fluids, and the exposed surfaces were put facing up [18]. The cleaning time is set as 1 min, 2 min, and 5 min.…”

Air pollution has become a matter of close concern to people with the continuous development of human society. However, the knowledge of air pollution mechanisms remains insufficient, and there is a lack of evaluation methods for actual pollution. In this paper, air pollution in Internet cafe was studied by detecting surface topography of glass slides after different exposure time by an atomic force microscope (AFM). It is found that the adsorption of air pollutants on glass surface undergoes initial aggregation, particle growth and interparticle deposition, and final full coverage. The chemical composition of contaminated glass surface was further analyzed by an X-ray photoelectron spectrometer, showing that the pollution was mainly composed of hydrocarbons regardless of exposure time. Cleaning experiments show that NaHCO3 solution can be the most effective one with saponification reaction and hydrolysis to remove the adsorbed contaminations. This study provides an alternative way for investigating air pollution and a reference for cleaning polluted material surfaces.
