In this paper, we have investigated the ion temperature gradient (ITG) driven electrostatic drift waves in the presence of non-thermal electrons that follow the generalized ( r , q ) distribution. In the linear regime, we have derived the linear dispersion relation of the coupled drift-ion acoustic wave. In the nonlinear regime, stationary solutions of the nonlinear equations have been obtained in the presence of gradients in equilibrium density, temperature and magnetic field. It has been found that the tail parameter q and the flatness parameter r strongly affect the profiles of linear and non-linear propagation characteristics of ITG driven electrostatic drift ion acoustic waves. It has been found that the flat-topped distribution augments the growth rate of the ITG driven electrostatic modes under consideration which is undesirable from the confinement stand point. It has also been shown that the double spectral indices r and q affect the structure o...

具有广义（r，q）分布的空间非均匀磁等离子体中ITG模式驱动的涡旋。

在本文中，我们研究了在遵循广义（r，q）分布的非热电子存在下，离子温度梯度（ITG）驱动的静电漂移波。在线性状态下，我们导出了耦合漂移离子声波的线性色散关系。在非线性状态下，在平衡密度，温度和磁场存在梯度的情况下，已经获得了非线性方程的平稳解。已经发现，尾部参数q和平坦度参数r强烈影响ITG驱动的静电漂移离子声波的线性和非线性传播特性。已经发现，平顶分布增加了所考虑的ITG驱动的静电模式的增长率，这从限制的观点来看是不希望的。还显示出双光谱指数r和q影响结构o ...
