对大直径同轴相对论返波管采用双板波纹波导模型结合电子运动的罗伦兹力方程、电荷连续性方程和电磁波麦克斯韦方程建立了系统的线性流体理论.使用该理论详细地研究了器件的各系统参数对束波相互作用,特别是对微波指数增长率的影响.给出了3cm波段的大直径同轴相对论返波管实验装置的系统参数.

The impact of SDT on arms race has been discussed in a model which includes intercontinental ballistic missiles, anti-FCBM satellites and anti-satellite weapons for U.S. and former Soviet Union. It is assumed that each side of U. S. and former Soviet Union wants to reach the biggest retaliatory capability for given expenditure. This problem is considered as a two-person game and the optimal configurations of the three kinds of weapons for both sides is calculated under different conditions. The results show that the SDI can not lead to the transition from an offensive mode to a defensive mode and can not also offer an effective protection against the threat of ICBMs.

本文推导了考虑中子之间碰撞的非线性中子输运方程,提出了求解该方程的n-n逐次碰撞展开法,并利用此方法把方程化为适于数值求解的线性输运方程组的形式,编制计算程序进行了数值计算,讨论了解的物理意义。
