摘要
论述了激光闪光法热扩散率测量仪的工作原理，分析了装置中温度测量系统可能存在的干扰源，以及采取的抗干扰措施。通过比对试验，验证了所取得的实际应用效果。
The operation principle of the laser flash method thermal diffusivity meter is described. The possible sources of interference of the temperature measurement system is analyzed, and the anti-jamming measures was taked. By comparing the test, the obtained practical of results ware verified.
