Abstract

The main results of a completed cycle of complex studies of a strongly coupled dusty plasma conducted in the unique, experimental Plasma Crystal-3 Plus space laboratory that operated on the International Space Station are discussed. The experiments on the physics of phenomena in the dusty plasma are analyzed. A new state of dusty plasma, the electrorheological plasma, in which there is a transition from an isotropic plasma-dusty liquid to an anisotropic state, is studied. The study of the interpenetration of particles streams of various diameters, a nonequilibrium transition, is described. Experimental studies of the liquid–crystal phase transition in a three-dimensional dusty plasma system in which it is established that the dust component is compressed and crystallized upon a decrease in the neutral gas pressure are discussed. The nearly free motion of large particles in the volume of a plasma crystal, a nonviscous, irrotational flow about a large particle by a “liquid” of small dust particles, is analyzed. An experimental study of the dynamics of the crystallization of three-dimensional plasma-dust systems at a constant argon pressure under the effect of a low-frequency, alternating electric field and without its influence under microgravity conditions is described. The formation of the crystallization front and its propagation in the three-dimensional plasma-dust system with a velocity on the order of the average interparticle distance per second were discovered.

摘要

讨论了在国际空间站上运行的独特，实验性的Plasma Crystal-3 Plus空间实验室中完成的强耦合尘埃等离子体复杂研究的完整循环的主要结果。分析了粉尘等离子体中现象物理学的实验。研究了一种新的尘埃等离子体状态，即电流变等离子体，其中从各向同性等离子体尘状液体过渡到各向异性状态。描述了各种直径的粒子流互穿的研究，即非平衡转变。讨论了三维尘埃等离子体系统中液晶相变的实验研究，其中确定了尘埃成分在中性气压降低时被压缩和结晶。分析了大颗粒在等离子晶体体积中的几乎自由运动，即由小尘埃颗粒的“液体”围绕大颗粒进行的非粘性无旋流。描述了在低频，交变电场的作用下且在微重力条件下不受其影响的，在恒定氩气压力下三维等离子粉尘系统结晶动力学的实验研究。发现了结晶前沿的形成及其在三维等离子-粉尘​​系统中的传播速度为每秒平均粒子间距离的数量级。描述了在低频，交变电场的作用下且在微重力条件下不受其影响的，在恒定氩气压力下三维等离子粉尘系统结晶动力学的实验研究。发现了结晶前沿的形成及其在三维等离子-粉尘​​系统中的传播速度为每秒平均粒子间距离的数量级。描述了在低频，交变电场的作用下且在微重力条件下不受其影响的，在恒定氩气压力下三维等离子粉尘系统结晶动力学的实验研究。发现了结晶前沿的形成及其在三维等离子-粉尘​​系统中的传播速度为每秒平均粒子间距离的数量级。
