style="text-indent:25px">相位差測量兩個正弦電量可以是電壓和電流，或者一個是電壓，一個是電流等，對應(yīng)點通常是從負到正的過零點，相當(dāng)于正弦電函數(shù)的初始相位角。相位差的單位是度或弧度，正負號表示超前或滯后關(guān)系。一種由于被測相位差正弦電量的頻率范圍很寬，所以通常根據(jù)頻率選擇測量方法和儀器。常用的方法有直接法和間接法。一種直接法：用指針式相位計、數(shù)字相位計等專用儀器或用負示波器測量相位差。當(dāng)使用陰極示波器時，將兩個相同頻率的正弦電壓信號分別加到示波器的X軸和Y軸上。然后兩個正弦電壓之間的相位差為∮=電弧正弦（B/α）。</p><p>
