| 2 | Application of Noise Reduction Method Based on Birgé-Massart Threshold显示文摘Flue gas generator set is a kind of large high-speed rotating machinery in petrochemical industry.This research focuses on noise reduction algorithms basis ontheBirgé-Massartthreshold.Obtained the threshold through Penalization Strategy Provided by Birgé-Massart;constructed different modulus maximum vertex neighborhood on different wavelet transform decomposition scales to influence the search process of modulus maximum point;obtained the appropriate modulus maximum points sequence on various wavelet decomposition scales;highlighted state feature information;finally usedMallat staggered projection to reconstruct signals.In order to validate the effectiveness of the algorithm,it was compared with four kinds of threshold noise suppression methods namely Rigrsure,Sqtwolog,Heursure,Minimaxi.The results show that this algorithm has a better signal to noise ratio and mean-square error. | Xu Xiaoli Jiang Zhanglei Zuo Yunbo Wu Guoxin | 2013 | 仪器仪表学报2013，34，S1： | 1 |
| 3 | Tribological Properties of Ti-DLC Coatings on Piston-pin Surfaces显示文摘A magnetically filtered cathode vacuum arc deposition system was used to deposit Ti-doped diamond-like carbon coatings(Ti-DLC)on pin surfaces to improve the wear resistance of high-power density diesel engine piston pins.The coating structure,composition,and morphology were characterised using field emission scanning electron microscopy(FE-SEM),X-ray photoelectron spectroscopy(XPS),Raman spectroscopy,and other techniques.Friction tests were carried out using a universal tribometer to study the tribological properties of pins with or without coatings under dry friction and oil lubrication.The surface morphology and cross-sectional morphology of the Ti-DLC coating show that the coating has a uniform crosssection and good surface properties.The XPS spectrum shows that the coating contains Ti-C,Ti-C*,sp2-C,sp3-C,and C-O/C=O.Raman spectroscopy shows that there is an amorphous carbon phase in the Ti-DLC coating.The friction test shows that the friction temperature increase of the pin with the Ti-DLC coating is lower than that without the coating,especially under dry-friction conditions.At the end of the test,the difierence in temperature increase is 16.7%.The friction coefficient when using high-viscosity lubricating oil with a coating is relatively lower than that without a coating,especially under low-speed and heavy-duty conditions.In the dryfriction state,the coated surface has better wear resistance than the uncoated surface,which primarily manifests as abrasive wear,and the surface without a coating mainly experiences adhesive wear. | LIU Jiliang XIANG Jianhua ZUO Zhengxing XIE Guoxin LUO Jun SHENG Yongqing | 2023 | Journal of Wuhan University of Technology(Materials Science)2023，38，5： | 0 |
