Large amplitude fast ion-acoustic solitons are revisited in a three-component plasma composed of cold ions, warm (adiabatic) ions, and hot Boltzmann electrons to determine where the limits occur in the ranges of the warm ion-to-electron temperature ratio τ and the charge-to-mass ratio of the cold ions relative to the warm ions μ for the existence of stopbands. The warm (adiabatic) ion limiting curve evolves in a similar fashion for increasing values of τ or decreasing values of μ in supporting the existence of stopbands when the warm ion limiting curve is double-valued in the Mach number over part of a range of cold ion densities, to the disappearance of the stopbands when the warm ion limiting curve is single-valued over the complete range of cold ion densities. The bifurcation of the warm ion limiting curve into an upper and lower branch indicates the transition region in parameter space, which is between the region where stopbands are supported and the region where stopbands do not occur. The stopbands...

关于快速离子声孤子阻带和扩展到尘埃等离子体的新见解

在由冷离子、热（绝热）离子和热玻尔兹曼电子组成的三组分等离子体中重新审视大振幅快速离子-声孤子，以确定在热离子-电子温度比 τ 范围内出现极限的位置对于阻带的存在，冷离子相对于热离子 μ 的荷质比。热（绝热）离子限制曲线以类似的方式演变为增加 τ 值或减少 μ 值以支持阻带的存在，当热离子限制曲线在冷范围的一部分上以马赫数为双值时离子密度，当热离子限制曲线在整个冷离子密度范围内为单值时，阻带消失。热离子限制曲线分为上下分支表示参数空间中的过渡区域，该区域介于支持阻带的区域和不出现阻带的区域之间。阻带...
