The invention discloses a method for simulating phosphorus and chromium migration during farmland irrigation with acid mine wastewater, which comprises the following steps: mixing a plant-derived organic material with deionized water to obtain a soluble organic matter; h2O2 oxidizes Fe < 2 + > to prepare pure Schwertmannite, and the pure Schwertmannite is placed in a phosphate solution to obtain phosphorus-loaded Schwertmannite; mixing the phosphorus-loaded Schwertmannite and the soluble organic matter with a chromate solution, carrying out oscillation adsorption, carrying out solid-liquid separation after adsorption, carrying out CrO and POconcentration change test on filtrate, and carrying out mineral characterization on separated solids; a three-dimensional fluorescence spectrum is adopted to track composition conversion of the soluble organic matter in the reaction process; and analyzing the component change of the supernate before and after the reaction by adopting Fourier transform ion cyclotron resonance mass spectrometry. The influence mechanism of DOM on phosphorus and chromium fate in mineral / water interface molecular fractionation is disclosed from the molecular level, and a scientific basis is provided for collaborative migration risk assessment of phosphorus and heavy metal in acid mine wastewater irrigation area farmland.

This invention provides a tear collection patch, comprising, from near to far from the eye, a biomimetic flexible substrate, a superhydrophilic drainage layer, a storage cavity, and a sealing cap. The superhydrophilic drainage layer includes a hydrophilic medical fiber membrane and a superhydrophilic coating. The hydrophilic medical fiber membrane is prepared by electrospinning medical hydrophilic fibers, and the superhydrophilic coating is formed by immersing the hydrophilic medical fiber membrane in a superhydrophilic coating solution and then curing it. The biomimetic flexible substrate has a biomimetic adhesive layer that automatically adheres to the target location. The superhydrophilic drainage layer absorbs tears into the storage cavity. This invention achieves instantaneous tear absorption and painless adhesion by designing a drainage layer with superhydrophilic properties and a biomimetic adhesive substrate working synergistically. The biomimetic adhesive substrate reduces the risk of corneal irritation, ensuring that the collected tears are in a normal physiological state rather than due to stress secretion, thus solving the problems of reliance on manual operation and low efficiency in traditional collection methods.

A segmented planar imaging system based on a beam splitter includes a lens array comprising lens columns. Microlenses within each lens column are paired to form baselines. These baselines are formed by the interference of light rays from two microlenses as a set of interference beams. Each microlens has two baseline formation methods. The imaging system also includes a photonic integrated circuit and an image processing module. The photonic integrated circuit includes an integrated beam splitter, an arrayed waveguide grating, waveguide transmission lines, and multiple balanced quadrature detectors. Each lens column is connected to one photonic integrated circuit. In this segmented planar imaging system, each microlens participates in forming two baselines via a beam splitter, and individual interferometer arms employ complementary baseline pairing methods. This increases the acquisition of spatial frequency information lacking in traditional systems, further improving the imaging quality of the system.
