style="text-indent:25px">相位常應用在科學領域，如數(shù)學、物理學等。例如：在函數(shù)y=Acos(ωx+φ)中，ωx+φ稱為相位。在astrolog32中點擊ALTIFT+A可以顯示相位設定菜單。在交流電中，相位是反映交流電任何時刻的狀態(tài)的物理量。交流電的大小和方向是隨時間變化的。比如正弦交流電流，它的公式是i=Isin2πft。i是交流電流的瞬時值，I是交流電流的比較大值，f是交流電的頻率，t是時間。隨著時間的推移，交流電流可以從零變到比較大值，從** 大值變到零，又從零變到負的** 大值，從負的比較大值變到零。在三角函數(shù)中2πft相當于弧度，它反映了交流電任何時刻所處的狀態(tài)，是在增大還是在減小，是正的還是負的等等。因此把2πft叫做相位，或者叫做相。</p><p
