摘要翻译：
具有吸收（俘获）态的系统可能表现出从无噪声的非活动相到持久的活动相的非平衡相变。本文简要回顾了吸收临界现象和普适类，并对扩散对接触过程(PCPD)中有争议的问题进行了讨论。提出了两种不同的方法来澄清其普遍性问题，这有力地证明了PCPD属于定向渗流类之外的一个新的普遍性类别。

英文摘要：
  Systems with absorbing (trapped) states may exhibit a nonequilibrium phase transition from a noise-free inactive phase into an ever-lasting active phase. We briefly review the absorbing critical phenomena and universality classes, and discuss over the controversial issues on the pair contact process with diffusion (PCPD). Two different approaches are proposed to clarify its universality issue, which unveil strong evidences that the PCPD belongs to a new universality class other than the directed percolation class.
