This paper constructs a parameter inverse analysis model for the diffusion analysis experiments of multi-ion transport model. It transforms multi-parameter inverse analysis problem into an optimization problem for nonlinear constrained planning. The optimization principle, the sequential quadratic programming method (SQP) for optimization and its(More)
Microplastics (MPs) are a significant environmental health issue and increasingly greater source of concern. MPs have been detected in oceans, rivers, sediments, sewages, soil and even table salts. MPs exposure on marine organisms and humans has been documented, but information about the toxicity of MPs in mammal is limited. Here we used fluorescent and(More)
Peatlands contain large amount of carbon stock that is vulnerable to release into the atmosphere. Mostly because of human impact, the peatlands at Zoige Wetlands face severe degradation, and the groundwater table is now lower than before, which has increased the population of the plateau zokor, a burrowing rodent. However, the impact of these changes on(More)
Poisson-Nernst-Planck (hereinafter referred to as PNP) is applied to describe ion transport in clay microscale structure and obtain the macroscopic PNP multi-ions transport model in clay through volume averaging. Use numerical analysis to research microscale quantities such as ion background concentration and particle surface charge density as well as the(More)
