| 摘 要： | 为了实现恶劣环境下瞬态高温的精确测量，设计了基于原子发射双谱线测温原理的光电测温器。采用高温黑体炉对光电测温器进行特定常数静态标定实验，选用CuⅠ 510.5nm和CuⅠ 521.8nm两条波长间隔小的谱线作为测温时的温标谱线，得到了测温常数A的值为0.1083，B的值为628.387。对标定后的光电测温器进行Cu燃烧温度场温度测试实验，并与计量部门标定过的M5型红外测温仪测量的标准温度进行比较。结果表明，两种方法测得温度的平均相对误差为1.3%。该研究为原子发射双谱线测温法准确测量瞬态高温提供了理论依据。

Experimental study on static calibration of atomic emission spectroscopy temperature constant |

| Abstract: | A photoelectric thermometer was designed based on the temperature measurement principles of double line of atomic emission spectroscopy, which could be used to measure the transient high temperature in complicated environment. The static constant calibration experiment was conducted, where CuⅠ 510.5nm and CuⅠ 521.8nm were selected from the atomic spectra database as the temperature measurement element spectral lines. In the obtained constant values, A and B were 0.1083 and 628.387, respectively. Cu combustion temperature field was measured by the calibrated photoelectric thermometer. The obtained data was compared with temperatures measured by M5 infrared thermometer calibrated by the metrology department. The results show that the average relative error for the two methods is 1.3%, which provides a theoretical basis for the accurate measurement of transient high temperature by the atomic emission spectroscopy method. |
