style="text-indent:25px">相位介紹相位是與電路結(jié)構(gòu)有關(guān)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(fù)的比較大值，從負(fù)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(biāo)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(dāng)訊號波形以周期的方式變化，波形循環(huán)一周即為360°。常應(yīng)用在科學(xué)領(lǐng)域，如數(shù)學(xué)、物理學(xué)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(jī)構(gòu)。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(guān)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(jié)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(yīng)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(kuò)展到相鄰的頻率中去，產(chǎn)生了邊帶(sideband)。對應(yīng)樣品尺寸：可定制。江蘇質(zhì)量相位差測量儀性價比高</p><p
