摘要
为了减小环境温度变化对原子钟性能的影响，必须对钟房进行恒温控制。提出一种钟房恒温控制的新方法，在普通室内实现了密闭小环境的高精度和高稳定度温度控制，使钟房（面积5～9 m^2，高2．2～2．5 m）的温度波动长期调控在特定温度的±0．3～0．5℃范围内。实践证明该方法效果好，具有较高的实用价值，目前已成功应用于昆明站，并已推广到三亚和盱眙等观测站。
In order to reduce influences of variations of environmental temperatures on the performance of an atomic clock, it is necessary to put the atomic-clock room （ the room hosting the atomic clock,） under thermostatic control.In this paper we present a new method of thermostatic control of an atomic-clock room.We have used this method to achieve thermostatic control of a usual small insulated room with high precision and high stability.Particularly, the method can achieve long-term temperature stability for an insulated atomic-clock room of an area of 5m^2 to 9m^2 , with the deviation of the room temperature from a desired temperature controlled within a level of 0.3℃ to 0.5℃.Our experiments show that the method is feasible, can achieve satisfactory results, and is practically highly valuable.After having been successfully used for an atomic-clock room in Kunming, this method and related equipments are being used for atomic-clock rooms in Sanya and Xuyi.
