In this erratum we explain how to implement two axioms stated in our paper of 2009 so as to get a purely “local” characterization for finite $B_2$-crystals, which was declared but not clarified at some moments there. Also we correct some inaccuracies in that paper.

勘误表为“ B _2-晶体：公理，结构，模型” [J．梳。理论先生 A 116（2009）265–289]

在这个错误中，我们解释了如何实现2009年论文中所述的两个公理，从而获得有限的纯“局部”特征 ${乙}_2$-晶体，在此处已声明但尚未澄清。我们也纠正了该论文中的一些错误。
