摘要
考虑大气环境下密度和温度梯度非均匀量子等离子体系统,研究该系统在离子与中子碰撞频率较低情形下的二维非线性流体动力学扰动孤立子波模型,利用双曲函数展开法和摄动理论及方法,得到了该系统在天体物理环境中的势函数,并给出其物理意义.
We considered the density and temperature gradients of an inhomogeneous quantum plasma system in the atmospheric environment, and studied the two-dimensional nonlinear fluid dynamics disturbed solitary wave model in the case of low collision frequency between the ions and neutrons. By using the hyperbolic function expansion method and perturbation theory and method, we obtained the potential function of the system in the astrophysical environment and gave its physical meaning.
