摘　　要：简要介绍了示踪气体测定自然通风量的原理及三种测量方法各自的使用特点,围绕目前使用较广的示踪气体浓度衰减法,对示踪气体源类型及用量、测试方法、测试方案、后期数据处理产生的测量误差进行分析,最后针对主要影响因素提出了改进思路。Introduces the principle of natural ventilation measurements by using tracer gas techniques and the features of three measuring methods. Some relative factors （type and amount of tracer gas, testing methods, testing scheme and date processing） were discussed to find the main factors in this paper based on the widely adopted tracer decay method, then put forward some improvement ideas for the main factors.y as the simulation only using TRNSYS, but also it can be more convenient than the simulation only using TRNSYS.

关 键 词：示踪气体自然通风量误差改进思路
