50477 采用基于准则的方法以及改进惯性权重等措施，以两个目标作为引导，在备件配置方案生成时可以避免长时间的无效搜索，提高了粒子群优化算法的求解效率， based on the principles of methods, and improve the inertia weight, measures such as guide, with two goals as the spare parts configuration scheme generation can avoid long invalid search, improved particle swarm optimization algorithm's efficiency,
50478 最后通过算例证明该方法的可行性和有效性。 and finally USES case to prove the feasibility and effectiveness of the method.
50479 当系统某次评价不达标，选取怎样的方案使系统整改后达标便是评价后续决策问题。 When an evaluation system is not up to standard, the selection standard is how to plan the system improvement after evaluation of subsequent decision problem.
50480 首先类比事故树基本事件重要度，建立能综合反映指标重要度的模型及改善代价的模型; Basic event importance first analogy of accident tree, can establish comprehensive reflection index important degree model and improve the cost model;
50481 之后对最大重要度所对应指标得分进行固定步长、渐升步长以及渐降步长等3种形式的增值，再求新的系统评价得分，直到系统评价满足阈值，并确定3种迭代模型的取舍策略; After the maximum importance index score which corresponds to a fixed step length, rising step as well as the gradual decline step length and so on 3 kinds of appreciation, and seeking, the score of the new system meets the threshold until the system evaluation, and to determine three iteration model of trade-off strategy;
50482 最后分析迭代过程及结果，建立指标改变先后度模型，确定指标改变的轻重缓急次序。 In the final analysis the iterative process and results, establishes the index change successively degree model, determine the priorities of the index change order.
50483 文中以模糊综合评价方法为对象分析，实例验证切实可行，并可推广应用于灰色评价、可拓学评价以及集对分析等常规评价方法。 With fuzzy comprehensive evaluation method for the analysis of object, the instance validation is feasible, and can be applied in grey evaluation, evaluation of extenics, the set pair analysis of conventional evaluation methods, etc.
50484 空时码应用最广泛的是空时分组码(space-time block code，STBC)和垂直分层空时码(vertical bell layered space-time code，VBLAST)， Space-time code is the most widely used space-time block codes (STBC, space - time block code) and vertical layered space-time code (vertical bell layered space - time code, VBLAST),
50485 因为STBC信号具有时间上的相关特性，所以在求高阶循环累积量时，该信号有一个特殊的循环频率，而VBLAST信号没有此特性。 because of STBC signal with time on relevant properties, therefore, when strives for the high-order cyclic cumulants, the cycle of the signal has a special frequency, and VBLAST signal without this feature.
50486 提出了一种基于循环稳定特性的STBC多载波码分多址(multicarrier code division multiple access，MC-CDMA)信号识别算法。 Is put forward based on the cycle stability characteristics of STBC multicarrier code division multiple access (multicarrier code division multiple access, Mc-cdma) signal recognition algorithm.
