求翻译：为有效诊断船舶柴油机燃油系统故障，设计并组建了小波神经网络。利用小波变换模极大值分析燃油压力信号的奇异性，提取故障特征向量；根据故障采集数据并建立学习样本，通过网络训练建立神经网络输入和输出间的非线性映射；进而通过输入特征向量来诊断故障。经实验数据分析验证，该方法具有良好的诊断效果。是什么意思？

For effective fault diagnosis of marine diesel engine fuel system, designed and established a Wavelet neural network. Analysis of fuel pressure signal using Wavelet transform modulus maxima of singularity, extraction of fault features vector; depending on the failure the acquire the data and the establishment of the learning sample, established through the network training neural network nonlinear mapping between the input and output; in turn through the import feature vector to diagnose the fault. An experimental analysis of the data verified, the method has a good diagnostic quality.
