Within the kinetic approach the velocity and the charge distributions of grains in stationary dusty plasmas are calculated and the relations between the effective temperatures of such distributions and plasma parameters are established. It is found that the effective temperature which determines the velocity grain distribution could be anomalously large due to the action of accelerating ionic bombarding force. The possibility to apply the results obtained to the explanation of the increasing grain temperature in the course of Coulomb-crystal melting by reduction of the gas pressure is discussed.
在动力学方法中，计算了稳态尘埃等离子体中颗粒的速度和电荷分布，并建立了这些分布的有效温度与等离子体参数之间的关系。结果发现，由于加速离子轰击力的作用，决定颗粒速度分布的有效温度可能异常高。讨论了将所得结果应用于解释通过降低气压使库仑晶体熔化过程中颗粒温度升高的可能性。
