[en] Dust particles, immersed in a plasma, acquire charge due to which they may be electrostatically trapped in a plasma. The energy of the interaction of the dust particles may be enough to transfer the dust component to nonideal and even crystalline state. This phenomenon is observed in various plasmas. In the present work a review of the investigations of strongly nonideal dusty plasma of the dc glow discharge striations is given. The formation of plasma crystals, liquids and plasma liquid crystals is considered. Typical phenomenon a for the dc discharge dusty plasma, such as coexistence of different phases in a single structure, convective motions, dust acoustic instability, are underlined. Results of the experiments on different external influences on dusty plasma structures are stated. It is shown that external influences may be used for measuring of the particle charge and field of forces acting on a dust grain levitating in a plasma. (author)

[en] The results of the experimental study on the dynamics of the bronze large (of the order 70-180 μm) spherical particles in the direct current glow discharge under the microgravitation conditions are presented. The temperatures velocities, pair correlation functions and macroparticles self-diffusion coefficients by the discharge current different values are measured. The registered charges (of the order 106 e) of the dust particles corresponded to the high surface potentials of the order 30-40 V. The experimental data agree well with the results of the Yukawa system modeling under the conditions of the dust charges low screening. The effect of the macroparticles on the processes of the equilibrium ionization in the dense dust cloud is considered

Представлены результаты экспериментального исследования динамики крупных (порядка 70-180 мкм) сферических частиц бронзы в плазме тлеющего разряда постоянного тока в условиях микрогравитации. Измерены температуры, скорости, парные корреляционные функции и коэффициенты самодиффузии макрочастиц при различных значениях разрядного тока. Регистрируемые заряды (порядка 106 е) пылевых частиц соответствовали высоким поверхностным потенциалам порядка 30-40 В. Экспериментальные данные хорошо согласуются с результатами моделирования систем Юкавы в условиях слабого экранирования пылевых зарядов. Рассмотрено влияние макрочастиц на процессы равновесной ионизации в плотном пылевом облакеJournal
