On the basis of fatigue test under high-low two stresses loading, the paper testifies that the equivalent damage lines do not parallel each other and tend to converge slightly over the fatigue limit. 本文根据高低二级应力作用下的疲劳寿命试验,验证了等损伤线互不平行且向下汇聚。
Most high-low band system using RFID readers to provide power to the passive labels, so as to reduce the size of labels and costs, but it will limit the scope and the capacity to read. 大多数低高频段的RFID系统采用从阅读器获取电源的被动式标签,这样有利于减小标签尺寸和降低成本,但是会限制读取范围和数据存储能力。
