不平行的晶面之间的夹角称作晶面夹角 在一晶体的格子结构中，沿不方向可以构成许多组 这样相互平行的晶面，不晶面间彼此相差一定角度，并且 他们的晶面间距、面密度及质点种类、价键密度也不，这 将导致这些晶面的物理、化学性质有所不。 A trip up Dom Tower makes a good afternoon activity. For one of the best views over the city, climb the 465 steps to the top of the tower. Dom Tower is the tallest belfry in The Netherlands.
