| 2 | Phase Structure and Electrochemical Properties of Rare Earth Based Hydrogen Storage Alloys显示文摘The rare earth based hydrogen storage alloys MmxM1 1 - x ( Ni3.55 Co0.75 Mn0.4 A10.3 ) ( x = 0 ~ 0.5 ) were investigated in this work.Adjusted Ml: Mm ratio to change the content of La,Ce,Pr and Nd in the alloys and then to change the phase structure, the influences of phase structure on the electrochemical properties were analyzed.The results indicate that the main phase of all alloys is LaNi5 with CaCu5 type structure and the crystal lattices constants of LaNi5 are changed with increasing x value, i.e, decreased a-axis, increased c-axis and axis ratio and nonlinear decreased crystal volume.The crystal volume of the alloy with x = 0.3 is larger than others.There is second phase A1LaNi4 in alloys when x≥0.3, which decrease the discharge capacity, but increase the cycling stability and high rate discharge ability.Compared comprehensively, the alloy with x = 0.3 shows the higher discharge capacity and the better cycling stability. | Chen Weidong Liu Xiangdong Liu Xiao Che Guangdong | 2004 | Journal of Rare Earths2004，22，z1： | 1 |

| 4 | Provably Secure APK Redevelopment Authorization Scheme in the Standard Model显示文摘The secure issues of APK are very important in Android applications.In order to solve potential secure problems and copyrights issues in redevelopment of APK files,in this paper we propose a new APK redevelopment mechanism(APK-SAN).By exploring sanitizable signature technology,APK-SAN allows the original developer to authorize specified modifier who can redevelop the designated source code of APK files.Our scheme does not require interactions between the developer and modifiers.It can reduce the communication overhead and computational overhead for developers.Especially,the signature of redeveloped APK files is valid and maintains the copyrights.The proposed APK-SAN signature can effectively protect the security of the redeveloped APK files and copyrights of the developer and modifier. | Daofeng Li Mingxing Luo Bowen Zhao Xiangdong Che | 2018 | Computers, Materials & Continua2018，，9： | 0 |
