Keyword钟房 恒温 控制

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 m2,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。

Other Abstract

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 5m2 to 9m2, 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.
