摘要: Abstract The forms and the step distances of polygomized spirals growth arising from emergence points screw dislocations are calculated taking into account that propagation rate steps depends on length. A rather unexpected result is obtained showing ratio between distance d radius ρ c inscribed circle in geometrical form nucleus independent (i.e. number corners) spiral equal to approximately 19, very near value this for a circular by Cabrera Levine.
