| 1 | Characterization of a Mg_(95.5)Zn_(1.5)Y_(3)alloy both containing W phase and LPSO phase with or without heat treatment显示文摘The influence of solid solution treatment on the microstructure and corrosion resistance of as-cast Mg_(95.5)Zn_(1.5)Y_(3) alloy is characterized.The microstructure of the as-cast Mg_(95.5)Zn_(1.5)Y_(3) alloy mainly consisted ofα-Mg,W(Mg_(3)Zn_(3)Y_(2))phase,and the long period stacking ordered(LPSO)(Mg_(12)ZnY)phase.After solid solution treatment,most of the W phase disappears gradually with increasing solution treatment time,with only a small amount of W phase distributed as particle.The LPSO phase slightly dissolved into substrate,and its morphology transitions from blocky shape to rod shape.Solid solution treatment of Mg_(95.5)Zn_(1.5)Y_(3) exhibits excellent corrosion resistance,because the Y and Zn atoms became enriched in the matrix and the changed morphologies of the LPSO and W phases were modified through heat treatment.The alloy created with solid solution treatment at 520 ℃ for 10 hours exhibits corrosion potential of−1.419 V,suggesting a significant improvement in corrosion performance. | Li Zhumin Wan Diqing Huang Yi Ye Shuting Hu Yinglin | 2017 | Journal of Magnesium and Alloys2017，5，2： | 8 |
| 2 | GENERATOR VIBRATION FAULT DIAGNOSIS METHOD BASED ON ROTOR VIBRATION AND STATOR WINDING PARALLEL BRANCHES CIRCULATING CURRENT CHARACTERISTICS显示文摘Rotor vibration characteristics are first analyzed, which are that the rotor vibration of fundamental frequency will increase due to rotor winding inter-turn short circuit fault, air-gap dynamic eccentricity fault, or imbalance fault, and the vibration of the second frequency will increase when the air-gap static eccentricity fault occurs. Next, the characteristics of the stator winding parallel branches circulating current are analyzed, which are that the second harmonics circulating current will increase when the rotor winding inter-turn short circuit fault occurs, and the fundamental circulating current will increase when the air-gap eccentricity fault occurs, neither being strongly affected by the imbalance fault. Considering the differences of the rotor vibration and circulating current characteristics caused by different rotor faults, a method of generator vibration fault diagnosis, based on rotor vibration and circulating current characteristics, is developed. Finally, the rotor vibration and circulating current of a type SDF-9 generator is measured in the laboratory to verify the theoretical analysis presented above. | Wan Shuting Li Heming Li Yonggang Tang Guiji | 2005 | Chinese Journal of Mechanical Engineering2005，18，4： | 2 |

| 4 | Spontaneous pain as a challenge of research and management in chronic pain显示文摘Spontaneous pain occurring without apparent external stimuli,is a significant complaint of individuals with chronic pain whose mechanisms,somewhat surprisingly,remain poorly understood.Over the past decades,neuroimaging studies start to reveal brain activities accompanying spontaneous pain.Meanwhile,a variety of animal models and behavioral tests have been established,including non-reflexive tests and free-choice tests,which have been shown to be effective in assessing spontaneous pain.For the spontaneous pain mechanisms,multiple lines of research mainly focus on three aspects:(1)sensitization of peripheral nociceptor receptors and ion channels,(2)spontaneous neuronal firing and abnormal activity patterns at the dorsal root ganglion and spinal cord level,(3)functional and structural alterations in the brain,particularly the limbic system and the medial pain pathway.Despite accumulating evidence revealing distinct neuronal mechanisms from evoked pain,we are still far from full understanding of spontaneous pain,leaving a big gap between bench and bedside for chronic pain treatment.A better understanding of the neural processes in chronic pain,with specific linkage as to which anatomical structures and molecules related to spontaneous pain perception and comorbidities,will greatly improve our ability to develop novel therapeutics. | Longyu Ma Shuting Liu Ming Yi You Wan | 2022 | Medical Review2022，2，3： | 0 |
