Question

a new intelligent fault diagnosis scheme based on the extraction of statistical parameters from the paving of a wavelet packet transform(WPT), a distance evaluation technique (DET) and a support vector regression (SVR)-based generic multi-class solver is proposed.The collected signals are first pre-processed by the WPT at different decomposition depths. In this paper, the wavelet packet coefficients at different decomposition depths are referred to as WPT paving.Statistical parameters are then extracted from the signals obtained via the WPT at different decomposition depths. In selecting the sensitive fault features for fault pattern expression, a DET is employed toreduce the dimensionality of the feature space.
analysing the complex signals they produce to allow judgment concerning diagnosis requires considerable expertise.

the mapping of the original signals onto the statistical parameters concerned

Answer 1

你好啊！

a new intelligent fault diagnosis scheme based on the extraction of statistical parameters from the paving of a wavelet packet transform(WPT), a distance evaluation technique (DET) and a support vector regression (SVR)-based generic multi-class solver is proposed.
这是一种包含了距离评估技术和一个以多类别支持向量回归的解决器在内的，基于提取（观察、分析、研究）小波包变换系数统计参数的新型智能故障诊断方法。

注：开头的俩个字“这是”是为了配合整个句子我自己加进来的，为了使句子完整。“a support vector regression (SVR)-based generic multi-class solver ”被我译成“一个以多类别支持向量回归的解决器”我自己觉得不对，可是我专业知识匮乏，实在不知道应该如何理解。

The collected signals are first pre-processed by the WPT at different decomposition depths.
被收集到的信号首先用不同深度层次的小波包变化进行技术处理。

In this paper, the wavelet packet coefficients at different decomposition depths are referred to as WPT paving.
在本篇论文中，不同层次深度下的小波包系数即作为小波包参数。

Statistical parameters are then extracted from the signals obtained via the WPT at different decomposition depths.
统计参数随即被不同深度层次所获得的小波包变换信号中提取（分析）出来。

In selecting the sensitive fault features for fault pattern expression, a DET is employed toreduce the dimensionality of the feature space.
在为故障进行图形模式描述时选择突出的故障图形的过程中，距离分析技术被用来解释特定区域的量纲。

analysing the complex signals they produce to allow judgment concerning diagnosis requires considerable expertise.
利用分析他们产生的复杂信号来判断故障需要相当丰富的专业知识。

the mapping of the original signals onto the statistical parameters concerned
注：最后这句不完整，无法翻译。

希望帮到了你 祝你好运！追问

Fault feature extraction is the most basic of these steps and involves the mapping of
the original signals onto the statistical parameters concerned to reflect the health of the machine.

Answer 2

根据统计参数从小波包的铺路变换（WPT）提取一个新的智能故障诊断方法，距离评估技术（DET）和支持向量回归（SVR）为基础的通用多类求解器建议。收集到的信号首先在不同的分解深度预处理的WPT。在本文中，在不同的深度分解的小波包系数被称为WPT paving.Statistical参数然后经由WPT在不同深度的分解所获得的信号中提取。在选择用于故障模式表达敏感的故障特征，一DET采用会调低特征空间的维数。
