.位错理论被用来定义二维固体的长程有序。在低温下存在有序状态，并且在转变温度下刚性模量不为零。类似的论点表明，在二维超流的转变温度下，超流密度不为零。
. Dislocation theory is used to define long range order for two dimensional solids. An ordered state exists at low temperatures, and the rigidity modulus is nonzero at the transition temperature. Similar arguments show that the superfluid density is nonzero at the transition temperature of a two dimensional superfluid.
