perpendicularity

n.

垂直，直立；垂直度；

1. Exact perpendicularity between the components must be maintained.
   各分量之间必须严格地保持互相垂直。
2. Mounting inaccuracies in parallelism and perpendicularity during the installation can create uneven loads on the ball screw system, causing abnormal noises.
   在平行和垂直方向不精确的安装可以导致不均匀的载荷，这些会导致不正常的噪音。
