位差的單位是度或弧度，正、負(fù)號表示搶先或滯后聯(lián)系。待測相位差的正弦電量的頻率規(guī)模很廣，因此選用的丈量辦法和儀器一般隨頻率的高低來挑選。常用的辦法是直接法和間接法。間接法一般選用三電壓表法。 -般要求兩電壓信號有一-公共點(diǎn)(設(shè)為a點(diǎn))，當(dāng)分別測出兩信號電壓Uab、Uca, 以及兩電壓的差值Ubc后，江蘇日本大冢相位差測量儀質(zhì)量推薦, 可畫出電壓三角形。按余弦定理，江蘇日本大冢相位差測量儀質(zhì)量推薦,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。相位差測試儀有AXOSCAN相位差測試儀。江蘇日本大冢相位差測量儀質(zhì)量推薦</p><div

入偏振片與液晶顯示板之間或者偏振片出現(xiàn)變形的情況。這時，為了再利用液晶顯示板，采用將偏振片從液晶顯示板上剝離，貼合新的偏振片的工序（再加工工序）。但是，當(dāng)形成偏振片的保護(hù)膜與起偏振器的粘合力弱時，將該偏振片剝離時，有時保護(hù)膜與起偏振器會剝離。這時，液晶顯示板上殘留有保護(hù)膜，要附加剝離保護(hù)膜的工序，因此制造效率下降。 </p> <p>
