1. The simulations worked well enough to hint at the power of true parallelism. 模拟工作卓有成效，足以暗示真正并行处理器的威力。
2. In our nation, we have lots of methods and equipments to detect the parallelism of visible light. 国内现有的平行度检测方法和检测设备都是用于检测可见光的平行度。
3. It is important to measure the parallelism of artillery bore axes and its aiming axes for the distribution of hitting points. 火炮瞄准轴和炮膛轴的平行性直接影响火炮弹着点的散布，是需要检测的重要静态参数之一。
