The oblique wave instability is studied extensively in cylindrical bounded quantum plasmas. This study emphasizes on role of quantum features of a plasma system like Fermi degenerate pressure, exchange-correlation potential and Bohm potential as well as the radius of cylindrical geometry on the instability. The growth rate is studied for two cases depending upon the ion gyro time scales. It is found that the growth rate for both cases decreases in a plasma column with the characteristics of wave vector and the parameters like plasma number density, poles of Bessel function and waveguide radius. On increasing these arguments, decreasing of the growth rates respond differently. Numerical analysis of this study is presented on the basis of astrophysical plasma parameters, however, it may be equally useful in the laboratory and discharge plasma technology for some typical set of parameters. Despite the fact of numerous possible applications in technology, the motivation may be exten...

量子等离子体中的倾斜波导不稳定性

在圆柱有界量子等离子体中对斜波不稳定性进行了广泛的研究。这项研究强调等离子体系统的量子特征，如费米简并压力，交换相关势和玻姆势，以及圆柱几何半径对不稳定性的作用。根据离子陀螺仪的时间尺度，研究了两种情况下的生长速率。结果表明，在两种情况下，具有波矢量特性和等离子数密度，贝塞尔函数极点和波导半径等参数的等离子柱，增长率均下降。在增加这些论点时，增长率下降的反应不同。这项研究的数值分析是基于天体物理等离子体参数提出的，但是，对于某些典型参数集，它在实验室和放电等离子体技术中可能同样有用。尽管存在技术中可能存在的众多应用，但其动机可能会延续。
