translation symmetry
 Translation Symmetry
 Трансляционная симметрия
  Тип симметрии, при которой объект совмещается с собой при сдвиге на определённый вектор, называемый вектором трансляции. Трансляционной симметрией обладают кристаллы. В этом случае векторы трансляции не произвольны, хотя их существует бесконечное число. Среди всех векторов трансляций кристаллической решётки можно выбрать 3 линейно независимых таким образом, что любой другой вектор трансляции был бы целочисленно-линейной комбинацией этих трёх векторов, которые составляют базис кристаллической решётки.
