摘要： This invention discloses a method for treating sand or sandy soil in desert or desertified land, comprising spreading water and a solid organic substance in any order or by directly spreading an adhesive and cohesive solution containing the solid organic substance onto the surface of desert or desertified land, and then stirring the solution containing the solid organic substance or mixing water and the solid organic substance with sand on the surface of desert or desertified land in a uniform way by a stirring device to finally form a modified sand material. This sand treatment method can be directly implemented on the surface of desert or desertified land without transporting and discharging the mixture onto the surface of desert or desertified land, and thus saving cost and time.

摘要： The invention introduces a hydrodynamic free-surface Lattice Boltzmann (LB) simulation method and system, along with a storage medium. Initial parameters for a designated water body are obtained and fed into a pre-established three-dimensional hydrodynamic free-surface LB model for simulation calculations. The outcome includes precise data on the free water surface, flow velocity, and pressure of the target water body over time and space, generating a detailed three-dimensional spatial distribution map. The method enhances the second-order accuracy of the force term within the single-phase free-surface LB model. By integrating the single-phase free-surface LB model with surface tension and the SGS large eddy model, it achieves an efficient and accurate three-dimensional simulation of the target water body's free water surface, flow field, and pressure. The approach boasts a straightforward algorithm, robust expandability, excellent parallelism, and easy handling of boundary conditions, distinguishing it from conventional models.

摘要： An efficient and energy-saving blasting method based on a notched blast hole includes forming a cutting hole, an auxiliary hole, and a peripheral hole on a surface of an area to be blasted separately by means of a drilling apparatus. The cutting hole, the auxiliary hole, and the peripheral hole are formed on the surface of the blasting area separately, and notches with different numbers are formed on outer sides of the holes separately, such that in a blasting process, explosion energy of explosives can be transmitted along the notches, the explosion energy is guided, energy loss is reduced, blasting efficiency is improved, thus a range of a crushing area is reduced, a length of a main crack is increased, and a better blasting effect is achieved. Moreover, explosive energy is concentrated on the notch to initiate crack, so as to reduce an explosion smash area.

摘要： The invention discloses a multi-field coupled Lattice Boltzmann (LB) simulation method and system designed for heat and mass transfer flow, along with a storage medium. Initial parameters of a target water body are acquired and imported into a pre-set multi-field coupled LB model for heat and mass transfer flow simulation. This process yields flow velocity distribution, temperature distribution, and pollutant concentration distribution information, facilitating the accurate depiction of a three-dimensional spatial distribution map of the flow field, temperature field, and concentration field of the target water body. Through the integration of a total energy distribution LB model and a passive scalar model via a force term, bidirectional coupling of the flow field, temperature field, and concentration field is achieved. This establishes a multi-field coupled LB model capable of accurately simulating water temperature and quality, surpassing conventional methods in water temperature simulation accuracy.
