摘要：
研究了一维尘埃等离子体晶体中横向尘埃晶格波的调制不稳定性。的幅度调制机制，这是有关的鞘层电场的固有非线性，示出在一定条件下的载波不稳定，可能导致形成本地化的包络激发。给出了不稳定性增长率和阈值的显式表达式，并进行了讨论。
英文摘要：
The occurrence of the modulational instability (MI) in transverse dust lattice waves propagating in a one-dimensional dusty plasma crystal is investigated. The amplitude modulation mechanism, which is related to the intrinsic nonlinearity of the sheath electric field, is shown to destabilize the carrier wave under certain conditions, possibly leading to the formation of localized envelope excitations. Explicit expressions for the instability growth rate and threshold are presented and discussed.
