用分子动力学方法模拟了微重力条件下尘埃等离子体中尘埃粒子的结构形成。结果表明，在低温下，尘埃粒子被组织成层状球壳。壳层的数量是系统尺寸和周围等离子体粒子屏蔽强度的函数，而对后者的依赖性要弱得多。模拟中适当考虑了尘埃粒子和等离子体粒子系统满足的电中性条件。
Structure formation of dust particles in dusty plasmas under microgravity has been simulated by the molecular dynamics method. It is shown that, at low temperatures, dust particles are organized into layered spherical shells. The number of shells is a function of the system size and the strength of screening by ambient plasma particles, while the dependency on the latter is much weaker. In the simulation, the condition of the charge neutrality satisfied by the system of dust particles and plasma particles is properly taken into account.
