摘　　要：介绍了一种带有三个黑体空腔的发射率测量系统.该测量系统能在-10～200℃范围内测量多个样品的发射率.测量系统的硬件由三腔黑体辐射源、计算机、红外测温仪和导轨装置组成,可同时测量标准样品、待测样品、标准黑体辐射源三组温度数据,并计算得出待测样品的发射率.同时,应用编程语言进行测量系统的界面设计,结合软件和硬件搭建出了一个自动化、便捷的实验测量系统.An emissivity measurement system with three-cavity blackbody was introduced. It could measure multiple samples＇ emissivity in the temperature range from --10 to 200 ℃. Hardware of the system consisted of a three-cavity blackbody radiation source, a computer, an infrared thermometer and a guide rail device. It was able to simultaneously measure the temperatures and emissivities of the standard sample, the test sample and the standard blackbody radiation source. An automated and convenient experimental measurement system is established by using the programming language to design the interface and by combining the software and the hardware.
