炮阵地赋予火炮基准射向的精度,在方向上直接影响射弹首群覆盖目标的实现.基于炮兵基本计算原理,提出了周视瞄准镜分划盘不动,指标动的概念,并提出火炮通用瞄准点分划计算公式,实验数据充分验证了此计算公式的正确性.利用此公式计算出的瞄准点分划来赋予火炮基准射向,可以排除使用方向盘时所带来的误差.利用此公式计算出的瞄准点分划可以直接给牵引火炮赋予基准射向,也可以检验自行火炮陀螺仪定向的精度.

In order to solve the problem of multi-sinks and multi-sources routing in wireless sensor networks(WSNs),a net model based on Anycast is proposed,and the energy consumption and network lifetime problems are studied.Topology,energy and path selection model of WSNs are respectively built.Type of data packets is regulated and a routing protocol based on Anycast is proposed.Simulation experiment show that this model can effectively share load of the network compared with LEACH protocol.When the number of nodes is up to 100,the number of base station increases from 3 to 6,and energy consumption of network decreases by 33.3 %,and the network lifetime is prolonged accordingly.

未来作战将以信息化条件为背景展开,在这一条件下,战争将在复杂电磁环境下进行,复杂电磁环境下,战场信息、决策系统及指挥员本身极易受电磁干扰的影响,本文主要对这种影响进行分析。
