Concerning the stipulation and statement for empirical formula and revised index in point loading strength test there are still some uncertainties in related specifications and manuals.
关于点荷载强度试验的经验公式及其修正指数的规定和论述 ,在相关的规范和手册中还有一些有待明确的方面 ,因此在岩土工程应用中存在着一定的局限性。
In this study, a gear fault diagnosis method is investigated based on wavelet analysis and modified exponential distribution (MED) technique.
提出了基于小波分析和修正指数分布(modifiedexponentialdistribution,MED)的齿轮故障诊断方法,该方法采用小波包将齿轮振动信号分解为若干个频率段,然后选择合适的频率段进行小波包重构,对重构后的信号进行MED分析,得到齿轮振动信号的小波包时-频分布,进而从中提取齿轮振动信号故障的故障特征。
The diameter distributions were simulated by the modified exponential distribution function for describing the stand structure, based on inventory data of broad-leaf forest in Changbai Mountain.
