求翻译：根据电子标签的工作频段不同，人们提出了不同的防碰撞方法。在高频（HF）频段，防碰撞技术一般用经典ALOHA协议；在超高频（UHF）频段，主要采用树分叉算法来避免碰撞。这两种方式均属于TDMA方式，应用比较广泛。在超高频和微波等频段，有人提出了FDMA和CDMA技术。是什么意思？

According to different working frequency of electronic labels, people made a different anti-collision method. In the high-frequency (HF) bands, anti-collision technology in general agreement with the classical ALOHA; in ultra-high frequency (UHF) band, mainly tree forking algorithm to avoid collisio

In accordance with the electronic label different from the band, there were different collision prevention methods. In the high frequency band (HF collision prevention, technology in general agreement with the classic ALOHA UHF); the Ultra high frequency (Band, primarily in the form of tree forks al
