| 摘 要： | 导出了无磁化无碰撞各向同性相对论正负电子对等离子体纵波的色散关系。使用逐次近似的标准技术，对两种极限情况下的纵波色散方程进行了解析研究。将完全色散方程进行变换，使它们完全适用于在需要完全相对论处理的温度范围内进行数值计算。用数值模拟方法得到了用解析方法不能得到的完全的色散曲线。

| Abstract: | The dispersion relations of superluminal waves for the longitudinal collective modes in unmagnetized, collisionless and homogeneous relativistic electron-positron plasmas are derived. Using the standard technique of successive approximations, an analytic study of longitudinal dispersion equations in two limiting cases is presented. The full dispersion equations are transformed so that they are well suited for numerical evaluation in the temperature range where a fully relativistic treatment is needed. Using... |
