摘　　要：研究了热重分析中不同升温速率对柴油机排气微粒中ＳＯＦ和无定型碳的热反应温度区间的影响，提出了热重分析柴油机微粒中ＳＯＦ的方法及条件。试验表明，该方法和测量条件可准确测定柴油机排气微粒中ＳＯＦ的含量。The affection of different temperature rising rate in thermogravimetric analysis on the soluble fraction in the diesel exhaust particulate and thermal reaction temperature interval of amorphous carbon are studied in this paper. The paper proposes the method and condition of analyzing the SOF in diesel exhaust particulate using thermogravimetry. The test result shows that the content of SOF in diesel exhaust particulate can be measured accurately using this method and measurement condition.
