此兩正弦電量可以同為電壓、電流，或一為電壓、一為電流等。對應(yīng)點常取正弦電量由負(fù)到正的過零點，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)號表示**或滯后關(guān)系。 </p> <p> 待測相位差的正弦電量的頻率范圍很廣，因此采用的測量方法和儀器一般隨頻率的高低來選擇。 </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，或采用陰級示波器來測量相位差。采用陰極示波器時，將兩同頻正弦電壓信號分別加到示波器的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哪一個**或滯后，并且在∮值接近零時，橢圓也退化接近成為一條直線，即b值很小，所以∮值很難測準(zhǔn) </p> <p> 間接法通常采用三電壓表法。一般要求兩電壓信號有一公共點（設(shè)為a點），當(dāng)分別測出兩信號電壓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，兩信號電壓間的相位差當(dāng)∮很小時，可將Uab或Uca中較大的一個信號電壓分壓，使分壓后兩信號的數(shù)值相等。 </p> <p> <br /> </p> <p> <br /> </p> <p> <br

A：否。①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），此光軸跟基準(zhǔn)邊的夾角。通常同偏光軸（透過軸）垂直相交。 ②軸角度定義適用于雙折射樣品（產(chǎn)生相位差的樣品），在國際上普遍定義為慢軸與基準(zhǔn)邊的夾角。 </p> <p> 2. Q：配向角（取向角）是指軸角嗎？ </p> <p> A：否。配向角是軸角在垂直方向的投影。當(dāng)水平放置樣品時，配向角=軸角。當(dāng)樣品傾斜時，配向角會隨著樣品的翻轉(zhuǎn)而變化，所以在測量配向角時候，需要知道樣品與水平面的夾角。 </p><p> 相位差測試儀是工業(yè)領(lǐng)域中是經(jīng)常用到的一般測量工具，比如在電力系統(tǒng)中電網(wǎng)并網(wǎng)合閘時，需要兩電網(wǎng)的電信號相同，這就需要精確的測量兩工頻信號之間的相位差。更有測量兩列同頻信號的相位差在研究網(wǎng)絡(luò)、系統(tǒng)的頻率特性中具備重要意義。相位測量的方法很多，典型的傳統(tǒng)方法是通過顯示器觀測，這種方法誤差較大，讀數(shù)不方便。為此，我們設(shè)計了一種數(shù)字相位差測量儀，實現(xiàn)了兩列信號相位差的自動測量及數(shù)顯。近年來，隨著科學(xué)技術(shù)的迅速發(fā)展，很多測量儀逐漸向“智能儀器”和“自動測試系統(tǒng)”發(fā)展，這使得儀器的使用比較簡單，功能越
