摘　　要：为确定服装保温性的科学测试方法,采用LD-1型服装保温仪分别在控制服装热阻和环境温度的情况下考查了服装系统的非稳态传热时间;在环境条件不变的情况下,考查了穿着方式对服装热阻的影响;在服装系统不变的情况下,研究了环境温湿度对服装热阻的影响。结果表明:非稳态传热时间会随着服装热阻的增大而延长,随着环境温度的降低而延长;在测量外套类服装时,必须内着一件标准内衣以减少"风洞效应";并且由于服装热阻的测量值会随着环境温度的升高而增大,从而影响服装热阻测量的准确性,因此所有的测量必须在接近服装的使用环境下进行。In order to determine a scientific test method of clothing thermal insulation performance, based on the LD-1 clothing insulation tester, the unsteady heat-transferring time of the clothing system was studied under the conditions of the control of the clothing thermal resistance and environment temperature. Under the constant environment conditions, the influence of dressing way on the clothing thermal resistance was studied; and under the constant clothing system, the influence of the environment temperature and humidity on the clothing thermal resistance was studied. The experimental results show that the unsteady heat-transferring time prolongs along with the increase of the clothing thermal resistance, and prolongs along with the decrease of the ambient temperature. When testing the coat type clothing, it is necessary to wear a standard underwear to reduce the wind tunnel effect. With the increase of ambient temperature, the measurement value of clothing thermal resistance will increase, which will affect the measurement accuracy of the clothing thermal resistance, thus all measurements must be carried out under conditions close to the clothing use environment close.
