摘要:

本文对现行空气中总悬浮微粒测定的恒重方法进行了分析和讨论，针对现行恒重的不足，对其进行了改进。提出了更为简便、易行的干燥恒重法，并对其原理进行了讨论，经过试验，能达到快速、准确恒重和称量的目的。

Abstract:

In TSP determination,a more simple and easier constant weight drying procedure is adopted. which has more advantages than it is,and its principle is discussed. Experiments evidence that the aim of rapidly operating and a good measuring acurracy can be ach
