differential thermogravimetry meaning in English

差热重量测定法
差示热重测定法
示差热重量法

The measurement of oxygen desorption activation energy by thermogravimetry ( tg ) and differential thermogravimetry ( dtg ) curves with different heating rates shows clear evidences that the behavior of tg , dtg , and desorption activation energy have some relations with the oxygen stoichiometry of the specimeri when temperature changes from 500c to 800c
采用多升温速率热重法得到的tg 、 dtg数据计算yba _ 2cu _ 3o _ ( 7 - x )的氧脱附活化能。实验表明，当温度在500 - 800范围变化时， tg 、 dtg的变化行为及脱附活化能明显的和样品的氧含量有关。
