To study the burning characteristics of moxa stick.
A self-designed moxa stick burning temperature measuring device, which was assembled with ALTEC intelligence digital setter and SJ-600 thermocouple, was used to conduct next four experiences: 1) embedding a thermocouple inside a moxa stick to measure peak burning temperature; 2) pulling a thermocouple embedded in the moxa stick at the proper rate to detect combustion stability; 3) elucidating temperature distribution of transverse section by measuring the temperature in the center, radius midpoint and lateral; 4) drawing temperature-time-space curves by pulling the thermocouples in the former three observation points.
The experiment indicated that the burning temperature peak of three-year moxa stick (Hubei Herbal Medicine St. Qichun Technology Co., Ltd.) was 848 degrees C which had good combustion stability. Furthermore, the temperature in the center, radius midpoint and lateral of transverse section were 843 degrees C, 731 degrees C and 410 degrees C, respectively, and its burning temperature-time-space curves was drawn, which showed the real-time burning temperature and the peak burning temperature and were regarded as ultimate indice to integrate the formers.
The measuring system elaborately reflecting the burning features of moxa stick may provide reference for manufacture industry of moxa stick quality criteria for its convenience and accuracy.
研究艾条的燃烧特性。
采用自行设计的艾条燃烧温度测量装置，该装置由ALTEC智能数字设定器和SJ - 600热电偶组装而成，进行以下四项实验：1）将热电偶嵌入艾条内部测量燃烧峰值温度；2）以适当速率拉动嵌入艾条的热电偶以检测燃烧稳定性；3）通过测量中心、半径中点和外侧的温度来阐明横截面上的温度分布；4）通过拉动前三个观察点的热电偶绘制温度 - 时间 - 空间曲线。
实验表明，三年陈艾条（湖北蕲春李时珍医药集团有限公司）的燃烧温度峰值为848℃，燃烧稳定性良好。此外，横截面上中心、半径中点和外侧的温度分别为843℃、731℃和410℃，并绘制了其燃烧温度 - 时间 - 空间曲线，该曲线显示了实时燃烧温度和燃烧峰值温度，被视为综合两者的最终指标。
精心设计的反映艾条燃烧特性的测量系统，因其便利性和准确性，可为艾条制造业的质量标准提供参考。
