We made use of wheatstone bridge to control ratio of heating power between the samples , thus , it enable to control and measure the differential heating power accurately . consequently , it improves sensitivity of the system . the resolution of the measurement can reach from 1 : 1000 to 1 : 10000 or better in comparison with the traditional differential technique 我們測量了聚苯胺及其摻雜鹽酸后在1 . 8k至45k的熱容,利用聲子分形子模型來處理非晶態(tài)對(duì)比熱的貢獻(xiàn),對(duì)獲得的數(shù)據(jù)進(jìn)行處理,發(fā)現(xiàn)eb和es的比熱數(shù)據(jù)均不符合德拜理論,超出德拜模型的比熱來源于非晶態(tài)的貢獻(xiàn)。
