采用还原摄动法研究了含有热等温电子、离子（轻正离子和重负离子）和极大电荷波动尘埃颗粒的磁化多离子尘埃等离子体中的尘埃负离子声孤立波。给出了灰尘尺寸分布如何影响非线性孤立波的高度和厚度。值得注意的是，孤立波的特征随着粉尘粒径分布的不同而不同。外部磁场的大小也会影响孤立波的形式。
Dust negative ion acoustic solitary waves in a magnetized multi-ion dusty plasma containing hot isothermal electron, ions (light positive ions and heavy negative ions) and extremely massive charge fluctuating dust grains are investigated by employing the reductive perturbation method. How the dust size distribution affect the height and the thickness of the nonlinear solitary wave are given. It is noted that the characteristic of the solitary waves are different with the different dust size distribution. The magnitude of the external magnetic field also affects the solitary wave form.
