上述公式中(ωt+Φ)稱為正弦量的相位,它是表示正弦量變化進(jìn)程的物理量。例如:當(dāng)相位ωt+Φ=90°,e=Em,當(dāng)(ωt+Φ)=180°時(shí),e=0,如此等等。可見,相位隨時(shí)間不斷變化,電動(dòng)勢(shì)e也就不斷變化。由于相位是用電角度表示的,所以也稱相位角。
The above formula (omega t+) is called the phase of the sine quantity, and it is the physical quantity that represents the process of the sinusoidal variation. For example, when the phase Omega t+ =90 degrees, e=Em, when (omega t+) =180 degrees, e=0, and so on. It can be seen that the phase changes with time, and the electromotive force (EMF) e is constantly changing. As the phase is expressed in an electric angle, it is also known as the phase angle
