| 中文摘要: |
| 在大空间火灾实验中 ,由于测温系统的庞大和复杂 ,导致影响温度测量的误差因素增多。该文主要从热电偶测温误差理论分析入手 ,讨论全尺寸火灾实验温度测量误差的因素和大小 ,阐述了大空间烟气温度测量的误差引入方式和减少误差的措施 ,并对一组大空间内火灾机械排烟实验的温度数据进行了误差分析. |
| 英文摘要: |
| As the temperature measure system is large and complex in the large space fire test, the factors affecting measurement precision increase. In this paper, based on the theoretical error analysis of smoke temperature measurement by thermocouple, the error factors and magnitude of the smoke temperature measured in large scale fire tests are investigated. The manners of causing error are also introduced and the measures decreasing the error are given. At last an error analysis of a group of temperature data measured in mechanical smoke exhaust tests is made. |
