A possibility of four component dusty plasmas to self-oraganzie to Triple Beltrami state (a linear combination of three force-free Beltrami states) has been explored. It is found that the system attains a Triple Beltarmi state when the velocities of electrons and ions become parallel to magnetic field while the two oppositely charged dust grains follow the generalized vorticities. The impact of the densities of species, masses of charged dust grains and Beltrami parameters on the formation of self-organized structures has also been investigated. The present work is useful to study and understand the multi scale magnetic field structures formed in planetary bodies such as ionosphere of Mars, Titan’s lower ionosphere, etc. and in laboratory plasmas.

已经探索了将四组分尘埃等离子体转化为自Oraganzie到Triple Beltrami状态（三个无力Beltrami状态的线性组合）的可能性。发现当电子和离子的速度变得平行于磁场而两个带相反电荷的尘埃粒子遵循广义涡旋时，该系统达到三贝塔米状态。还研究了物种密度，带电尘埃颗粒质量和Beltrami参数对自组织结构形成的影响。目前的工作对于研究和理解在火星电离层，泰坦下电离层等行星体以及实验室等离子体中形成的多尺度磁场结构很有用。
