摘要
在用多输入／输出模型研究舰艇噪声源贡献定量估计的基础上，本文给出从条件输入和网络出发多种计算各输入到输出贡献的方法，对各方法作了分析。对输入间相互独立情况，不同方法计算的结果相同，对输入相干情况，不同方法计算的结果不同。还分析传统噪声测量与多输入／输出模型要求的噪声测量的不同，从多输入／输出模型出发，给出舰艇降噪的分析方法，并以两个计算例子说明。
Based on using multiple input/output model (MI/O) to research quantitative estimation of contribution ofsubmarine noise sources,several methods of calculating contribution of inputs to outputs (as viewed from conditionedinputs and network)are given and analysed in this paper. To independent inputs each other,calculated results are thesame ,to coherent inputs,calculated results are different. The differences between conventional noise measurement andnoise measurement required for multiple input/output model are also analysed. From multiple input/output model, themethod of analysis for reducing of submarine noise is given,and two calculating examples are illustrated.
