所以兩個(gè)溝通電動(dòng)勢(shì)，也可所以這三種量中的任何兩個(gè)。兩個(gè)同頻率正弦量的相位差就等于初相之差。是一個(gè)不隨時(shí)刻改變的常數(shù)。也可所以一個(gè)元件_上的電流與電壓的相位改變。兩正弦電量可以同為電壓、電流，或一為電壓、-為電流等。對(duì)應(yīng)點(diǎn)常取正弦電量由負(fù)到正的過零點(diǎn)，相當(dāng)于正弦電量函數(shù)的初相角。相.

大值變到零，又從零變到負(fù)的** 大值，從負(fù)的比較大值變到零。在三角函數(shù)中2πft相當(dāng)于弧度，它反映了交流電任何時(shí)刻所處的狀態(tài)，是在增大還是在減小，是正的還是負(fù)的等等。因此把2πft叫做相位，或者叫做相。軸角度測(cè)量范圍：0°~180° 數(shù)據(jù)輸出：電腦連接，軸角度精度：±0.05°。</p><div

</p> <p> 常用的方法： </p> <p> 直接法使用**的儀表如指針式相位表、數(shù)字相位表，或采用陰級(jí)示波器來測(cè)量相位差。采用陰極示波器時(shí)，將兩同頻正弦電壓信號(hào)分別加到示波器的X、Y軸，得到如圖1所示的橢圓圖形，則兩正弦電壓之間的相位差∮=arc 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。
