1Rotor Strength Analysis of High-speed Permanent Magnet Synchronous Motors显示文摘为了对转子进行有效的冷却,在满足电机电磁性能的前提下,可通过减小保护套的厚度来尽可能增大定转子之间的气隙,因而必须对保护套和永磁体进行强度校核。将转子受力状况简化为平面应变问题,在此基础上推导出了两层过盈配合、三层过盈配合转子的应力场、应变场、位移场的解析公式,并利用有限元方法验证了解析公式的正确性。归纳了高速情况下热套式永磁转子强度设计准则,为转子的优化设计提供了理论依据。以一台额定转速120kr/min、10kW的高速永磁同步电机为例,给出了两种常用过盈配合高速电机转子的强度设计方法。CHENG Wenjie GENG Haipeng FENG Sheng YU Lie SUN Yanhua YANG Lihua 2012中国电机工程学报2012,32,27:21
2Overexpression of connective tissue growth factor WISP-1 in Chinese primary rectal cancer patients显示文摘AIM: To clarify the expression change of Wnt-induced secreted protein-1 (WISP-1) in human rectal cancer and to determine whether it is correlated with invasion and metastasis of human rectal cancer. METHODS: Eighty-six paired samples of rectal cancer and surgically resected distant normal rectal tissue were collected and allocated into cancer group and control group respectively. WISP-1 mRNA was detected by relative quantitative real-time RT-PCR and WISP-1 protein was examined by immunohistochemical staining. RESULTS: WISP-1 gene overexpression was found in 65% (56/86) primary rectal cancers, 2-30 times that of the level in normal matched rectal tissues (P = 0.001). The mRNA expression level was correlated with Duke's staging, histological differentiation grade and lymph node status. The WISP-1 protein expression was in accordance with mRNA expression level. The positive degree of immunohistochemical staining in the cancer group (1.40 ± 0.35) was different from that in control group (1.04 ± 0.08, P < 0.001). Moreover, in cancer group the positive staining degree in high-level mRNA cancers (1.46 ± 0.37, n = 56) was higher than that in low-level mRNA (1.28 ± 0.28, n = 30, P = 0.018). CONCLUSION: Aberrant levels of WISP-1 expressionmay play a role in rectal tumorigenesis. WISP-1 may be used as a specific clinical diagnosis and prognosis marker in rectal cancer.Chao Tian Zong-Guang Zhou Wen-Jian Meng Xiao-Feng Sun Yong-Yang Yu Li Li Hong-Zhi Luo, Lie Yang Bin Zhou Jun Gu 2007World Journal of Gastroenterology2007,13,28:11
3Protonation induced high-T_c phases in iron-based superconductors evidenced by NMR and magnetization measurements显示文摘Chemical substitution during growth is a well-established method to manipulate electronic states of quantum materials, and leads to rich spectra of phase diagrams in cuprate and iron-based superconductors. Here we report a novel and generic strategy to achieve nonvolatile electron doping in series of(i.e.11 and 122 structures) Fe-based superconductors by ionic liquid gating induced protonation at room temperature. Accumulation of protons in bulk compounds induces superconductivity in the parent compounds, and enhances the Tclargely in some superconducting ones. Furthermore, the existence of proton in the lattice enables the first proton nuclear magnetic resonance(NMR) study to probe directly superconductivity. Using Fe S as a model system, our NMR study reveals an emergent high-Tcphase with no coherence peak which is hard to measure by NMR with other isotopes. This novel electric-fieldinduced proton evolution opens up an avenue for manipulation of competing electronic states(e.g.Mott insulators), and may provide an innovative way for a broad perspective of NMR measurements with greatly enhanced detecting resolution.Yi Cui Gehui Zhang Haobo Li Hai Lin Xiyu Zhu Hai-Hu Wen Guoqing Wang Jinzhao Sun Mingwei Ma Yuan Li Dongliang Gong Tao Xie Yanhong Gu Shiliang Lie Huiqian Luo Pu Yu Weiqiang Yu 2018Science Bulletin2018,63,1:7
4Experimental Studies on Support Systems of High Speed Motors With Flexible Squirrel-cage Support and Squeeze Film Dampers显示文摘以100kW级工作转速为45000r/min的高速永磁同步电机为实验样机,对采用鼠笼式弹性支撑和挤油膜阻尼器的滚动轴承支撑系统进行研究。分析了弹性支撑和挤压油膜阻尼器的刚度和阻尼特性,在此基础上分别计算出刚性支撑和弹性阻尼支撑时轴承一转子系统的临界转速和瞬态动力特性。最后在样机上进行对比实验,并对电机机壳振动加速度和弹性支撑笼条微应变信号进行分析。结果表明,弹性阻尼支撑可以使转子以较低的转速通过其刚体模态,同时对转子的振动起到良好的抑制作用。实验样机稳定运行在设计工作转速,其分析和实验结果为高速电机轴系设计和动力学分析提供了参考。TIAN Ye SUN Yanhua YANG Lihua YU Lie 2012中国电机工程学报2012,32,27:3

8Serum Calcium Level is Associated with Brachial-ankle Pulse Wave Velocity in Middle-aged and Elderly Chinese显示文摘Objective To study the relation between serum calcium level and elevated BaPWV in Chinese subjects.Methods The relation between serum calcium level and elevated BaPWV was studied in 9 615subjects.The mean value of left and right BaPWV was analyzed.BaPWV was defined as high when it was?1 752.5 cm/s(the upper quartile)either side.Results The BaPWV and its elevated percentage progressively increased across the quartiles of the serum calcium level(P<0.05).The prevalence of elevated BaPWV was significantly higher in subjects of the second,third and highest quartiles than in those of the lowest quartile(26.9%,28.4%,and 33.2%vs23.7%,P=0.0116,P=0.0004,and P<0.0001).Logistic regression analysis revealed that the risk of elevated BaPWV was 1.32-fold higher in subjects of the highest quartile than in those of the lowest quartile(OR=1.32,95%CI:1.08-1.60).Conclusion The elevated serum calcium level is related to an elevated BaPWV and a higher risk of arterial stiffness,independent of conventional risk factors,in middle-aged and elderly Chinese subjects.DENG Xin Ru ZHANG Yin Fei WANG Tian Ge XU Bai Hui SUN Ji Chao ZHAO Lie Bin XU Min CHEN Yu Hong WANG Wei Qing BI Yu Fang LU Jie Li 2014Biomedical and Environmental Sciences2014,27,8:2
