26325 共因失效普遍存在于现实的工程系统中。 Common cause failure generally exist in practical engineering system.
26326 如果忽略共因失效对系统的影响，按照传统假设其部件独立的方法进行可靠性分析会得出过于乐观的结论，并且作出认为系统符合可靠性需求的错误判断。 If you ignore altogether because of the influence of the failure of the system, according to the traditional hypothesis of independence to the components reliability analysis method of overly optimistic conclusion, and make that system can meet the demand of reliability.
26327 在考虑系统由部件选择性失效传播引起的共因失效的同时，提出了一种面向复杂系统的基于蒙特卡罗模拟(Monte Carlo simulation，MCS)与元胞自动机(cellular automata，CA)集成的可靠性评估算法。 Considering the system caused by components selective failure propagation of common cause failure at the same time, put forward a kind of complex system oriented based on Monte Carlo simulation (Monte Carlo simulation, MCS) and cellular automata, cellular automata, CA) integrated reliability evaluation algorithm.
26328 传统方法只能解决可以转化为串、并联结构的简单系统的可靠性评估问题，而所提出的算法打破了这种限制，使得其应用范围更加广泛。 Traditional methods can only solve simple systems can be converted into series and parallel structure problem of reliability assessment, and broke the limitation of the proposed algorithm, making its application is more extensive.
26329 圆轨迹环视合成孔径雷达(synthetic aperture radar，SAR)是一种能够实现广域观测的新模式合成孔径雷达，由于它特殊的运动轨迹，直线SAR的成像算法不能直接应用于圆轨迹环视SAR数据处理。 Circular orbit around a synthetic aperture radar (synthetic aperture radar, SAR) is a new mode of wide-area observation can be implemented synthetic aperture radar, due to its special trajectory, straight SAR imaging algorithms cannot be directly applied to circular trajectory around a SAR data processing.
26330 然而，对于圆轨迹环视SAR系统而言，其响应函数具有"沿角度维平移不变"的特性。 For circular path around a SAR system, however, the response function with "along the Angle d translation invariant features.
26331 因此可以利用这一特性，借鉴条带SAR成像算法的思想，在频域研究圆轨迹环视SAR数据的成像方法。 So can use this feature, referenced by the ideas of strip SAR imaging algorithm in frequency domain research circle trajectory around a SAR imaging method of data.
26332 推导了圆轨迹环视SAR回波信号的精确二维频谱表达式，并在距离多普勒域给出了一种圆轨迹环视SAR成像方法。 Accurate circular path around a SAR echo signal was deduced two-dimensional spectrum expression, and in the range doppler domain a circular trajectory around a SAR imaging method is given.
26333 仿真实验验证了算法的有效性。 The simulation results verify the effectiveness of the algorithm.
26334 主要研究在同步轨道卫星中的多用户接入控制方案，分析了现有时分多址接入(time division multiple access，TDMA)的优缺点，在基于TDMA的情况下给出了改进的自由接入/优先级按需分配接入方式(free access/priority demand multiple access，FA/PDMA)，保证多用户接入时的公平性，以及在业务量不断增大的过程中，如何在大传播距离下通过优化现有的多址接入算法来确保用户的接入时延和端到端时延； Research in geosynchronous satellite multi-user access control scheme, analyzes the existing time division multiple access (time division multiple access, TDMA), the advantages and disadvantages of the case based on TDMA improvement is given free access/priority to each according to his need access (free access/priority demand multiple access, FA/PDMA), ensure the fairness when the multi-user access, and in the process of business increasing, how to under large propagation distance through the optimization of the existing algorithm of multiple access to ensure that users access delay and end-to-end delay;
