style="text-indent:25px">相位差，物理學(xué)概念。兩個頻率相同的交流電相位的差叫做相位差，或者叫做相差。這兩個頻率相同的交流電，可以是兩個交流電流，可以是兩個交流電壓，可以是兩個交流電動勢，也可以是這三種量中的任何兩個。一臺高精度相位差測量儀對相位差的測量尤為重要。相位差與相位的關(guān)系（1）當(dāng)j12>0時，稱***個正弦量比第二個正弦量的相位越前（或超前）j12；（2）當(dāng)j12<0時，稱***個正弦量比第二個正弦量的相位滯后（或落后）|j12|；（3）當(dāng)j12=0時，稱***個正弦量與第二個正弦量同相，如圖7-1(a）所示；（4）當(dāng)j12=±π或±180°時，稱***個正弦量與第二個正弦量反相；（5）當(dāng)j12=±π/2或±90°時，稱***個正弦量與第二個正弦量正交。相位差示例1.已知u=311sin（314t-30°）V，I=5sin（314t+60°）A，則u與i的相位差為jui=(-30°）-(+60°）=-90°，即u比i滯后90°，或i比u超前90°。相位差的取值范圍和初相一樣，小于等于π（180°）.對于超出范圍的，同樣可以用加減2Nπ來解決.2.研究交流電路的相位差.如果電路含有電感和電容，對于純電容電路電壓相位滯后于電流（電壓滯后電流多少度也可以表述成電流超前電壓多少度），純電感電路電流相位滯后于電壓。吸收軸角度，是指透過光線在某一方向呈現(xiàn)吸收狀態(tài)(透光率比較低)。</p><div
