In their Comment, Rehman and Ahmad have noted that the damping rate of Langmuir oscillations in a q-nonextensive electron-positron plasma is always negative and so resulting only in Landau damped oscillations and no unstable modes. As a Reply, I would like to resolve the origin of the misleading result in Phys. Rev. E 87, 053112 (2013)10.1103/PhysRevE.87.053112, which had arisen from a misprint in numerical programming of one of the equations there. Furthermore, I would like to point out that this picture is not solely connected to the problem of Langmuir oscillations in an electron-positron plasma, but this is in fact a reemphasizing of the stability of q distribution as a decreasing function with velocity. In this Reply, the corrected and modified pattern of the Landau damping rate of Langmuir oscillations in an electron-positron plasma is given in the superextensive region q<1 (the subsection involved an inappropriate result) and the modified results are confirmed. Hereby, it is confirmed that all analytical solutions of Phys. Rev. E 87, 053112 (2013)10.1103/PhysRevE.87.053112 are true and the misleading result there arose from a misprint in numerical programming of one of the equations.
在他们的评论中，Rehman 和 Ahmad 指出，q 非广延电子-正电子等离子体中的朗缪尔振荡的阻尼率始终为负，因此只会导致朗道阻尼振荡，而没有不稳定模式。作为回应，我想解决 2013 年发表在 Phys. Rev. E 87, 05311210.1103/PhysRevE.87.053112 中出现的误导性结果的起源，该结果源于那里的一个方程的数值编程中的一个印刷错误。此外，我想指出的是，这种情况不仅与电子-正电子等离子体中的朗缪尔振荡问题有关，而是实际上是对 q 分布作为速度的递减函数的稳定性的再次强调。在本回应中，给出了在超扩展区域 q<1 中电子-正电子等离子体中的朗缪尔振荡的朗道阻尼率的修正和修改模式（这一节涉及不适当的结果），并确认了修正的结果。由此，确认 Phys. Rev. E 87, 053112（2013）10.1103/PhysRevE.87.053112 的所有解析解都是正确的，而那里的误导性结果是由于其中一个方程的数值编程中的一个印刷错误引起的。
