摘要 以带负电的尘埃颗粒、电子、高温非热离子和低温非热离子组成的热尘埃等离子体为研究对象,使用约化摄动法得到了描述尘埃声波的MKP方程.借用数学软件研究了系统参数对尘埃声孤波结构的作用和影响.结果表明,与冷等离子体相比,尘埃流体的温度和快离子数的变化均会显著影响和改变孤波的振幅和宽度;振幅随低温离子的数密度和其温度与电子温度的比值的增大而减小. In this paper, the reductive perturbation method has been used to derive the modified KP (MKP) equation for dust acoustic waves in an collisionless, unmagnetized hot dusty plasma have negatively charged dust particles, electrons with nonthermal distributions for higher temperature and lower temperature ions. The effects of dusty plasma parameters on the solitary wave structures are discussed by using mathematical software. The obtained results shows that the variations of dust fluid temperature and fast ions have significant contributions on the amplitude and width of solitons, furthermore, the amplitude will decreases with the lower-temperature ions density and the ratio of the temperatures of the lower temperature ions and the electrons increases.
