We have investigated the diamagnetic flow in a non-uniform partially ionized plasma with non-Maxwellian electron population to explain the dynamics of ion velocity shear-induced low-frequency drift mode and associated instabilities. The dispersion relations are found, and instability threshold conditions are pointed out along with ion-parallel momentum transport due to drift motion with relative phase shift of fluctuating quantities in a non-conservative system. The real frequencies and instability growth rates are studied numerically and illustrated for typical space and laboratory plasmas. This study should be useful in understanding some aspects of low-frequency time-delayed perturbations with sheared flow leading to drift instabilities and cross-field parallel ion momentum transport in nonuniform magnetoplasmas containing a non-Maxwellian electron population.

非麦克斯韦磁浆流中离子速度剪切诱导的漂移波和动量传输

我们研究了具有非麦克斯韦电子群的非均匀部分电离等离子体中的反磁流，以解释离子速度剪切引起的低频漂移模式和相关不稳定性的动力学。发现了色散关系，并指出了不稳定阈值条件以及由于非保守系统中波动量的相对相移的漂移运动导致的离子平行动量传输。对典型的空间和实验室等离子体的真实频率和不稳定性增长率进行了数值研究和说明。
