摘 要:
比对分析是工程信号分析与故障诊断的重要手段之一。论文提出并构建了3组可以分别适用于不同情况的数值比对算法，并建立了基于比对残差的渐变型故障分离和突发性故障诊断的实用方法。通过实例说明了比对分析方法在航天外测故障诊断等领域的重要应用。[著者文摘]

Abstract:
Comparison analysis is a key tool to analyze signal and to detect faults in engineering. There are three different kinds of algorithms are set up to compare signals. Based on these new algorithms, several practical approaches are built to detach gradual change and to diagnose abrupt faults. A practical example is given from a space - flight engineering mission to show that methods given in this paper are valuable.[著者文摘]
