复杂（尘埃）等离子体由弱电离气体和带电微粒组成，代表软物质的等离子体状态。由于“重”成分——微粒——以及周围介质、稀薄气体和等离子体的低密度，有必要在微重力条件下进行实验，以涵盖地面上无法获得的广泛实验参数。这些研究是在国际空间站（ISS）的“等离子体晶体- 3 Plus”（PK - 3 Plus）实验室的帮助下进行的。它非常适合形成大型稳定的液体和晶体系统，并提供了有趣的见解，如结晶和熔化，在二元混合物中倾斜，由于交流电场的电流变效应和弹丸与强耦合复杂等离子体云的相互作用。（©2016 WILEY‐VCH Verlag GmbH & Co. KGaA, Weinheim）
Complex (dusty) plasmas are composed of weakly ionised gas and charged microparticles and represent the plasma state of soft matter. Due to the “heavy” component – the microparticles – and the low density of the surrounding medium, the rarefied gas and plasma, it is necessary to perform experiments under microgravity conditions to cover a broad range of experimental parameters which are not available on ground. The investigations have been performed onboard the International Space Station (ISS) with the help of the “Plasma Crystal‐3 Plus” (PK‐3 Plus) laboratory. It was perfectly suited for the formation of large stable liquid and crystalline systems and provided interesting insights into processes like crystallisation and melting, laning in binary mixtures, electrorheological effects due to ac electric fields and projectile interaction with a strongly coupled complex plasma cloud.
