摘　　要：本文导出了无外磁场电子注在等离子体约束下其上传播的空间电荷波波动方程，详细讨论了该条件下的波特性，并对等离子体频率降低因子进行了分析．研究表明，等离子体填充状况对空间电荷波性质影响甚大，选择等离子体填充因子可对空间电荷波性质进行适当的控制．The space charge wave equation of electron ham in drifting tube filled with plasma and without external magnetic field is given in this paper.The wave properties are studied in detail under this condition and the plasma frequency reduction factor is also analyzed ,The study shows that the space charge wave properties are strongly related with plasma filling situation so the apace charge wave can be controlled to some extent by choosing plasma filling factor
