查询词典 a priori probability

When gas superficial velocity was about equal to liquid superficial velocity, the probability density function of liquid holdup had a twin-peaked, when liquid superficial velocity was constant, one of the peaks would fade out and disappear with the in crease of gas superficial velocity. Through using the characteristics, the relative size of gas and liquid superficial velocity can be set initially.

在段塞流动中，当气相折算速度和液相折算速度相差不大时，持液率概率密度函数呈双峰分布；当液相折算速度不变时，随着气相折算速度的增大，持液率概率密度函数第2峰值逐渐减小，直至消失而变为单峰分布；利用这一特征可初步确定段塞流动中气、液相流量相对大小。

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.
