一种新型选民资格证

针对站点式投票系统的实名制选民资格证如果在使用过程中暴露身份信息,易造成选民身份信息与选票挂钩的问题,设计一种匿名性新型选民资格证。新型选民资格证应用了基于伪随机序列发生器的生成序列号、图形码子母印章关联机制、集成物理防伪技术体系和可刮式涂层技术。其中序列号、图形码子母印章关联机制和集成物理防伪技术体系,使得新型选民资格证能够同实名制选民资格证一样,保障选举的不可重复性和合法性。可刮式涂层技术盲化序列号,使得新型选民资格证无任何特征,阻断选民身份信息和选票信息的产生对应关系的途径,保护了选举的匿名性。分析表明,在站点式投票系统中,相比于实名制选民资格证,新型选民资格证在保证不可重复性和合法性的前提下,有效地增强了选举匿名性。

Review on Preservative Treatment and Decay Resistance of Wood-based Composites

To extend the service life and explore the use of wood-based composites, it is quite necessary toimprove the decay resistance of wood-based composites through preservative treatments. Researchers havestudied the methods of preservative treatment and the decay resistance of treated wood-based composites.In this paper, the categories of wood-based composites are briefly summarized and the previous and presentinvestigations on the preservative treatment and decay resistance of different categories of wood-basedcomposites are introduced. Some problems are also put forward and suggestions are given for future studies.
