1. Let's try to measure the length between perpendiculars. 让我们试着测量垂线间距。
2. It is normal if two hands are in a line and perpendiculars to the floor. 标准姿势就是两只手在一条直线上与地面成直角。
3. For example, ancient Greek temples juxtapose tall vertical columns and wide horizontal entablatures to create rigid perpendiculars. 例如,古希腊庙宇就将高大的立柱与宽阔的横檐一并使用,以构造刚性的垂线。
4. Measuring hull's main dimensions: length overall(LOA. ), length between perpendiculars(LPP. ), breath molded(B. ), depth molded(D. ) and deflection before launching. 下水前测量船体主尺度:总长、两柱间长、型宽、型深、基线挠度。
