On the basis of analysis of pre - launch satellite ' s requirement to the environment in different stages in addition to the current state and defects of the satellite environment control system , the paper presents a new concept and specific method to design a new satellite environment control system by applying fuzzy logic theory . with the design and simulation of intelligent satellite environment control as the highlight , the paper illustrates that the basic means to realize the intelligent control is to design a fuzzy logic - based satellite environment controller 本文分析了卫星在发射场不同阶段对环境的要求，以及目前发射场卫星环境控制系统的现状及存在的问题，提出应用模糊逻辑控制理论，设计新的卫星环境控制系统的思路及具体设计方法，本文的重点是卫星环境的智能控制系统设计和模拟仿真，实现卫星环境智能控制的基本途径是设计基于模糊逻辑的卫星环境模糊逻辑控制器。
On the basis of analyzing the present situation and existing problems of the gas supply system in launch area , the thesis describes the general technical principles and parameters in the system designing and analyses the basic control functions the system should realize . and the thesis also shows the statistics of reference points in air 、 nitrogen and helium systems and related circuit diagram and pipe diagram 本文在分析了发射场配气系统的现状和存在的问题的基础上，提出了系统设计中的主要总体技术要求、参数，分析了系统应实现的主要控制功能，然后分别对空气、氮气和氦气系统的控制点进行了统计，并给出了有关的电路图和气路图。
Indirect ray method contains the following steps : the receiving plane wave field intensities on an adapted closed surface encloseing the antenna is calculated and then the radiation field of the antenna on the same closed surface is obtained from the given antenna . after using lorentz reciprocal theorem , the far field patterns with and without radome are gotten 间接射线法的分析步骤为:从参考面出发的入射平面波(经天线罩)在闭合面sa (在天线罩内且包围天线)上的接收场为et 、 ht ,天线在sa上的发射场为ea 、 ha ,由洛仑兹互易定理可求出天线的远区场。
Realizing automatic control and centralized monitor & control of the gas supply system will not only solve all kinds of problems and disadvantages under manual control at present , but also can be transplanted and extended to the monitor & control system of the equipment in other ground service support systems such as : low - voltage power distribution 、 cable arms 、 platform and air conditioning , which will finally become a part of the centralized monitor & control and telemetering launch system of the ground equipment 实现发射场配气系统的自动控制和集中监控，不仅可以解决目前手动控制存在的各种问题和弊端，而且项目的研究实施可以移植、扩展到低压配电、摆杆、平台、空调等地面勤务系统设备的监控上，并最终成为地面设备集中监控和远距离测试发射的一部分。
