查询词典 arithmetic data

On today of the arithmetic figure , for the sake of quickly school student status the management must depend on the calculator, and make the school management student is data more in brief, arrived the for, base onning above and all kinds reason, developping a student status managing the system forcing in the eyebrow , I join togethering this graduate designing to develop the student status the management the system.

在数字化的今天，为了加快学校学籍管理必须依靠计算机，以及使学校对教师数据的管理更加简单、到位，基于上述种种原因，开发一套教师信息管理系统迫在眉捷，我结合本次毕业设计的题目开发了教师信息管理系统。

First, it diagnoses and analyses the maglev train's suspension system and traction system by applying the FTA and fuzzy FTA method. Furthermore, it presents the new way to solute the diagnosis searching arithmetic by building the searching matrix based on the factors such as components' key weightiness, faults happen probability, searching cost. Then it can get optimal searching sequence for seeking the reason to the faults. Second, it builds the train's rank evaluation model based on multiple hiberarchy neural networks, after it takes the strategy that set the component diagnosis and whole train fault rank evaluation into two steps. Third, it deeply analyses reliability of the maglev train's power system with function-correlated feature, by the method that combining the FTA with the Markov model. Finally aiming at maintenance ahead of the fault, it proposes the blue print for the maglev train's maintenance. What's more, it introduces the design and realization to recorder for the train run data in detail.

应用故障树和模糊故障树分析法对磁浮列车悬浮系统、牵引系统进行全面的诊断分析，提出了以部件关键重要度、故障概率、搜索代价为因素，建立搜索决策矩阵，综合排序的搜索算法；采取部件诊断和列车集中评估相结合的分层诊断策略，建立基于多重神经网络的列车故障等级评估模型；结合故障树和马尔可夫模型对具有功能相关特性的列车电源系统进行可靠性分析；着眼事前维修，提出了列车运行维护方案，并设计实现了列车运行数据记录器。
