多晶石墨烯由以A角相互倾斜并由晶界（GB）分隔的完美畴组成。这些近一维区域依次由基本拓扑缺陷，5-五边形和7-七面体组成，通常配对成5-7位错。能量G（alpha）的GB计算为所有范围0
A polycrystalline graphene consists of perfect domains tilted at angle a to each other and separated by the grain boundaries (GB). These nearly one-dimensional regions consist in turn of elementary topological defects, 5-pentagons and 7-heptagons, often paired up into 5-7 dislocations. Energy G(alpha) of GB computed for all range 0
