本文利用故障树分析方法查找导致压缩机失效的所有可能性故障，并通过对故障机理和声发射原理的讨论，得出导致离心式压缩机失效的关键性声发射故障。
论文从声发射技术的基本理论入手，利用声发射参数分析方法，分析声发射信号在离心式压缩机中的传播特性，得出压缩机金属部件中表面传递与距离传递对声发射信号的影响。针对转子摩擦故障与轴承故障的声发射信号频谱特征进行了分析和提取，为进一步的实验研究与应用打下基础。
jiujiu99108辛苦，有几处专有名词还是想确定一下，
1.传递特性（特指声波的）communication feature 据我所知好像是（propagation propagation）
2..表面传递surface delivery 距离传递 distance delivery（这里的传递也不是propagation么？）
3.故障机理failure mechanism（这里的故障failure你确定么？不是fault么？）
4.声发射故障acoustic emission failure（问题同上failure？）
5.转子摩擦故障rotor friction failure（这样可以么，是不是friction fault of rotor）
6.在你回答问题后我又追加了50分，再给我翻译两个词吧：转子摩擦、轴承故障。
7.帮我检查一下单复数^^好像有不对的地方.
7.谢谢！希望得到确定回答，不确定的请直接告诉我，不会不给分的!(我想你也应该是学生吧^^)
Centrifugal compressor is a(这里不确定是用a还是the) key equipment in the petrochemical industry that can affects the normal operation of the whole industry system. The malfunction of it can cause huge economy loss, So it is quite important to analyse, diagnose and dispose the fault correctly and efficiently.
This paper analyses all the possible faults that lead to centrifugal compressor malfunction with fault tree analysis method.Through the discussion of failure mechanism and acoustic emission principle we can find the key acoustic emission failure that lead to centrifugal compressor malfunction.
It starts with the basic theory of acoustic emission technology.It analyses the communication feature of acoustic emission signal in the centrifugal compressor using the parametric analysis method and learns about how surface delivery and distance delivery in the metal part of the compressor affect the acoustic emission signal.It also analyses and extracts the spectrum feature of the roto
