style="text-indent:25px">相位差測(cè)試儀是工業(yè)領(lǐng)域中是經(jīng)常用到的一般測(cè)量工具，比如在電力系統(tǒng)中電網(wǎng)并網(wǎng)合閘時(shí)，需要兩電網(wǎng)的電信號(hào)相同，這就需要精確的測(cè)量兩工頻信號(hào)之間的相位差。更有測(cè)量兩列同頻信號(hào)的相位差在研究網(wǎng)絡(luò)、系統(tǒng)的頻率特性中具備重要意義。相位測(cè)量的方法很多，典型的傳統(tǒng)方法是通過顯示器觀測(cè)，這種方法誤差較大，讀數(shù)不方便。為此，我們?cè)O(shè)計(jì)了一種數(shù)字相位差測(cè)量儀，實(shí)現(xiàn)了兩列信號(hào)相位差的自動(dòng)測(cè)量及數(shù)顯。在相位差測(cè)量過程中，不允許兩路信號(hào)在放大整形電路中發(fā)生相對(duì)相移。為了使兩路信號(hào)在測(cè)量電路中引起的附加相移是相同的，圖1中A1和A2安排了相同的電路。</p><p style="text-indent:25px">相位差，物理學(xué)概念。兩個(gè)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(gè)頻率相同的交流電，可以是兩個(gè)交流電流，可以是兩個(gè)交流電壓，可以是兩個(gè)交流電動(dòng)勢(shì)，也可以是這三種量中的任何兩個(gè)。一臺(tái)高精度相位差測(cè)量儀對(duì)相位差的測(cè)量尤為重要。相位差與相位的關(guān)系（1）當(dāng)j12>0時(shí)，稱***個(gè)正弦量比第二個(gè)正弦量的相位越前（或超前）j12；（2）當(dāng)j12<0時(shí)，稱***個(gè)正弦量比第二個(gè)正弦量的相位滯后（或落后）|j12|；（3）當(dāng)j12=0時(shí)，稱***個(gè)正弦量與第二個(gè)正弦量同相，如圖7-1(a）所示；（4）當(dāng)j12=±π或±180°時(shí)，稱***個(gè)正弦量與第二個(gè)正弦量反相；（5）當(dāng)j12=±π/2或±90°時(shí)，稱***個(gè)正弦量與第二個(gè)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(duì)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(duì)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。專業(yè)性:光學(xué)博士團(tuán)隊(duì)合力研發(fā)，追求國產(chǎn)替代。</p><div
