此兩正弦電量可以同為電壓、電流，或一為電壓、一為電流等。對(duì)應(yīng)點(diǎn)常取正弦電量由負(fù)到正的過(guò)零點(diǎn)，相當(dāng)于正弦電量函數(shù)的初相角。相位差的單位是度或弧度，正、負(fù)號(hào)表示**或滯后關(guān)系。 </p> <p>

sin(b/α)。這一方法不能判斷兩信號(hào)哪一個(gè)**或滯后，并且在∮值接近零時(shí)，橢圓也退化接近成為一條直線，即b值很小，所以∮值很難測(cè)準(zhǔn) </p> <p> 間接法通常采用三電壓表法。一般要求兩電壓信號(hào)有一公共點(diǎn)（設(shè)為a點(diǎn)），當(dāng)分別測(cè)出兩信號(hào)電壓Uab、Uca，以及兩電壓的差值Ubc后，可畫出電壓三角形。按余弦定理，兩信號(hào)電壓間的相位差當(dāng)∮很小時(shí)，可將Uab或Uca中較大的一個(gè)信號(hào)電壓分壓，使分壓后兩信號(hào)的數(shù)值相等。
