style="text-indent:25px">相位介紹相位是與電路結構有關的參數(shù)。相位是反映交流電任何時刻的狀態(tài)的物理量。交流電的大小和方向是隨時間變化的。比如正弦交流電流，它的公式是i=Isin2πft。i是交流電流的瞬時值，I是交流電流的比較大值，f是交流電的頻率，t是時間。隨著時間的推移，交流電流可以從零變到比較大值，從比較大值變到零，又從零變到負的比較大值，從負的比較大值變到零。相位(phase)是對于一個波，特定的時刻在它循環(huán)中的位置：一種它是否在波峰、波谷或它們之間的某點的標度。是描述訊號波形變化的度量，通常以度（角度）作為單位，也稱作相角。當訊號波形以周期的方式變化，波形循環(huán)一周即為360°。常應用在科學領域，如數(shù)學、物理學等相位調(diào)整相位調(diào)整是指在有些**音音箱上加裝的一個控制機構。用于對**音音箱所重放出的聲音稍許加以延遲，從而讓**音音箱的輸出能夠和前置主音箱同相位，即具有相同的時間關系。相位噪聲相位噪聲是頻率域的概念，是對信號時序變化的另一種測量方式，其結果在頻率域內(nèi)顯示。如果沒有相位噪聲，那么振蕩器的整個功率都應集中在頻率f=fo處。但相位噪聲的出現(xiàn)將振蕩器的一部分功率擴展到相鄰的頻率中去，產(chǎn)生了邊帶(sideband)。江蘇日本大冢相位差測量儀價格實惠相位差測試儀：拉伸膜相位差測試儀。</p><div

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 </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（設為a點），當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∮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 />
