The propagation of some new electrostatic cnoidal, super-solitons, super-periodic and shocklike waves in Earth magneto-tail electron acoustic (EA) plasma at critical density has been investigated via MKP equation. These MKP solutions are obtained by the method of expansion Jacobian elliptic function (EMJEF). Numerous of the given solutions are significant on the observations of broadband electrostatic nonlinear noise forms in layers of magneto-tail.

临界等离子体密度下的超电子声传播

通过MKP方程研究了一些新的静电正弦波，超孤子，超周期和冲击波在临界密度下在地球磁尾电子声（EA）等离子体中的传播。这些MKP解是通过扩展雅可比椭圆函数（EMJEF）的方法获得的。许多给定的解决方案对磁尾层中宽带静电非线性噪声形式的观测都具有重要意义。
