论文摘要
在研究中,我们解决了地球地幔中质子迁移的数学问题,并提出了一个原型,用于探索地球内部,以绘制超离子质子传导的影响。可以通过得出自洽的电磁场电位u(x,t),然后重建分布函数f(x,v,t)来通过数学上解决该问题。检查了vlasov-Maxwell方程系统到非线性sh-gordon双曲线和传输方程,域内非线性波前的传播以及以非线性波的形式传输边界条件。通过计算3D模型并通过傅立叶分析,研究了潜在U(X,T)的空间和电特征。比较数值结果与通过电势场观察获得的电势(V)的傅立叶变换量(Kuznetsov方法)。针对两组分系统强制振荡的非平稳解决方案,因此,提出的数学模型可以用两种类型的带电粒子的振荡强度有效地解决。此外,该模型以及电势观察结果和概率地震危险图的数据分析可用于开发先进的地震风险度量。
In the study, we address the mathematical problem of proton migration in the Earth's mantle and suggest a prototype for exploring the Earth's interior to map the effects of superionic proton conduction. The problem can be mathematically solved by deriving the self-consistent electromagnetic field potential U(x,t) and then reconstructing the distribution function f(x, v, t). Reducing the Vlasov-Maxwell system of equations to non-linear sh-Gordon hyperbolic and transport equations, the propagation of a non-linear wavefront within the domain, and transport of the boundary conditions in the form of a non-linear wave are examined. By computing a 3D model and through Fourier-analysis, the spatial and electrical characteristics of potential U(x, t) are investigated. The numerical results are compared to the Fourier transformed quantities of the potential (V) obtained through field observations of the electric potential (Kuznetsov method). The non-stationary solutions for the forced oscillation of a two-component system, and therefore, the oscillatory strengths of two types of charged particles can be usefully addressed by the proposed mathematical model. Moreover, the model, along with data analysis of the electric potential observations and probabilistic seismic hazard maps, can be used to develop an advanced seismic risk metric.
