1. In a Stirling refrigerator, this phase angle is provided by the relative movement of the piston and the displacer. 在斯特林制冷机中，这一相位是由压缩活塞和冷头排出器的相对运动来提供的；
2. Cut-error that made from the finite difference migration, phase angle of error transfer function and factors that determine their values are discussed. 分析误差传递因子相角等因素对有限差分波动方程偏移造成的相位畸变问题，找到相应规律。
3. The term IMPEDANCE is applicable only to AC circuits. Its unit of measurement is the ohm. It has a magnitude as well as phase angle. It is a complex quantity. “感抗”这个术语只适用于交流电路，其测量单位为欧姆。感抗不但有幅值，而且有相角，它是一个复数量。
