| 1 | Terminal sliding mode control based on super-twisting algorithm显示文摘An improved non-singular terminal sliding mode control based on the super-twisting algorithm is proposed for a class of second-order uncertain nonlinear systems. This method can effectively avoid the singularity problem and obviously reduce the chattering phenomenon. The stability of the proposed procedure is proven to be finite-time convergence using the Lyapunov theory against uncertain unmodeled dynamic and external disturbances.An example is given to show the proposed improved non-singular terminal sliding mode control(SMC) law effectively. | Zhanshan Zhao Hongru Gu Jing Zhang Gang Ding | 2017 | Journal of Systems Engineering and Electronics2017，28，1： | 8 |

| 4 | Structure and Magnetic Properties of Sputtered Bi_(2)DyFe_(5)O_(12) Films显示文摘The effects of the annealing temperature and time on the structure and magnetic properties of the sputtered BiDy-iron garnet films were investigated.X-ray diffraction analysis shows that the as-sputtered films are amorphous.After annealing at about 550℃,amorphous films crystallize into the garnet phase and an unknown phase.The intensity of the unknown phase decreases with increasing annealing temperature and time and vanishes at 650℃for 30min.It is found that the unknown phase has a large influence on the half-width of the(420)x-ray diffraction peak.The as-sputtered films have a very small magnetization of about 1 emu/g at room temperature.When films are annealed above 570℃,the magnetization increases rapidly with increasing annealing temperature and time. | GU Benxi ZHANG Hongyan ZHAI Hongru LU Mu MIAO Yongzhi | 1994 | Chinese Physics Letters1994，11，1： | 0 |
| 5 | MAGNETIC ANISOTRIPY IN SPUTTERED NdFeB FILMS显示文摘The amorphous and crystalline NdFeB films were prepared by RF sputtering at differentsubstrate temperatures.The crystalline specimens,prepared at 600℃ have strong perpendicu-lar anisotropy and high coercivity.And the cystallized alloy from amorphous state also hasstrong perpendicular anisotripy. | Gu Benxi Zhai Hongru Nanjing University,Nanjing,ChinaH.Homburg S.Methfessel Ruhr-University Bochum,Germany | 1992 | Acta Metallurgica Sinica(English Letters)1992，5，8： | 0 |
| 6 | Effects of Fermentation Bed Cultivation Model on the Expression Amount of MSTN in Swine Gluteus and Its Correlation with Pork Quality显示文摘[Objective]The research aimed to discuss the differences of the expression amount of the related gene that regulated the development of muscles under different feeding environments.[Method] Using fluorescence quantitative PCR,the effects of fermentation bed cultivation model on the expression amount of MSTN in pig gluteus were studied and the correlation between its expression amount and the carcass quality of pig was analyzed.[Result]The relative expression amount of MSTN mRNA of swine gluteus under fermentation bed cultivation model decreased 8.6% by that under conventional cement ground feeding model,but there was no significant difference(P>0.05).The expression amount of MSTN mRNA in pig gluteus under conventional cement ground feeding model showed a significant negative correlation with shear force(P<0.05).The expression amount of MSTN mRNA in pig gluteus under fermentation bed cultivation model showed significant negative correlations with water content and muscle fiber diameter(P<0.05).The expression amount of MSTN mRNA in pig gluteus under two cultivation models had no significant correlation with other meat quality indices(P>0.05).[Conclusion]The research could provide test materials for the studies on the regulation of pork quality. | Pan Xiaoqing Yang Jie Xu Xiaobo Qin Feng Li Jian Huan Hailin Li Sheng Shao Le Zhang Xia Gu Hongru Liu Manchang | 2014 | Animal Husbandry and Feed Science2014，6，1： | 0 |
| 7 | CRYSTALLIZATION AND MAGNETIC PROPERTIES OF AMORPHOUS Nd_6Fe_(81)B_(13)ALLOY显示文摘The magnetic properties and the crystallization and its influence on the magnetic and struc-tural properties for rapidly quenched amorphous Nd6Fe81B-(13) alloy have been studied.The lowtemperature magnetic properties,the Curie temperature and the crystallization behavior arediscussed.A small addition(6at.-%)of Nd in amorphous Fe-B alloys increases largely thecrystallization temperature Tx but causes a decrease of the Curie temperature Tc·A newphase was observed in the sample annealed at 873 K. | GU Benxi ZHAI Hongru Nanjing University,Nanjing,ChinaSHEN Baogen Institute of Physics,Academia Sinica,Beijing,China | 1991 | Acta Metallurgica Sinica(English Letters)1991，4，8： | 0 |
