| 摘 要： | 铷灯内金属铷的消耗是决定铷原子钟工作寿命的主要因素。为了预估铷灯的工作寿命,基于瞬态热传导方程和非稳态质量扩散方程在数学形式具有相似性这一特点,通过有限元软件ANSYS建立能够预测Schott 8436玻璃铷光谱灯工作寿命的铷扩散模型,并通过对比有限元模型预测结果与中国科学院武汉物理与数学研究所7年铷量测试数据,验证了模型的准确性。通过验证后的有限元模型,探讨了相同扩散面积下,Schott 8436玻璃铷灯泡体积、外轮廓线曲率对铷量消耗的影响,相关结果为玻璃铷灯泡的选型提供了理论支持。 |

| Abstract: | The consumption of metal rubidium in rubidium lamp is the main factor determining the working life of rubidium atomic clock. In order to predict the working life of rubidium lamp, based on the similarity of transient heat conduction equation and unsteady mass diffusion equation in mathematical form, a rubidium diffusion model was established to predict the working life of Schott 8436 glass rubidium lamp by using the finite element software ANSYS, The accuracy of the model is verified by comparing the predicted results of the finite element model with the seven-year rubidium measurement data of Wuhan Institute of physics and mathematics, Chinese Academy of Sciences. Through the verified finite element model, the influence of Schott 8436 glass rubidium bulb volume and external profile curvature on rubidium consumption under the same diffusion area is discussed. The relevant results provide theoretical support for the selection of glass rubidium bulb. |
