Welch法：Welch法对Bartlett法进行了两方面的修正：一是选择适当的窗函数w(n)，并在周期图计算前直接加进去，加窗的优点是无论什么样的窗函数均可使谱估计非负。二是在分段时,可使各段之间有重叠，这样会使方差减小。(Welch method: Welch method of Bartlett method amendments in two respects: First, select the appropriate window function w (n), and in the cycle before CALPHAD directly incorporated, plus the advantage of the window, no matter what kind of window function can be so spectral estimation of non-negative. Second, when in subparagraph can overlap between paragraphs, this would reduce the variance.)

：文章从满足C 17设计基本要求人手，阐述了避免严重失速的机理、操纵失效概率、所有发动机停车操 纵以及安全复飞要求。对综合飞行控制系统设计做了介绍。对满足上述要求的FCS特性做了描述。最后对早期的飞行试验结果作了分析。(: Articles from the design to meet the basic requirements of C 17 staff, described the mechanism to avoid serious stall, control failure probability, all the engines go around parking control and security requirements. The integrated flight control system design is introduced. FCS on the properties meet the above requirements was described. Finally, the early flight test results are analyzed.)

这里提供了两个消除趋势相的matlab程序 在故障诊断中 要对信号进行频谱分析 而在频谱分析前要消除趋势相 这样得到的频谱 能更好的反映故障 有利于进一步诊断(Here are two trends in the elimination phase of the matlab program in fault diagnosis to the signal spectrum analysis and spectrum analysis in the former to eliminate the tendency of such spectrum can be better reflected further in favor of fault diagnosis)
