英文摘要	随着美国国防部先进项目研究局(Defence Advanced Research Projects Agency,DARPA)对微型定位导航授时技术的提出以及无人驾驶技术的发展,芯片级原子钟的市场越来越受到重视.稳定度是衡量芯片级原子钟性能的关键指标,而温度又是影响芯片级原子钟稳定度指标的重要因素,因此高精度的温控系统是芯片级原子钟稳定度的保障.设计了一种高精度的数字温度控制系统,控温精度为2mK.经过对比测试,使用该系统的芯片级原子钟稳定度较以前有了较大的改善,千秒稳定度从7.57×10-12提高到4.99×10-12,处于世界先进水平.; With the proposal of the Micro-PNT( Micro-Technology for Positioning, Navigation and Timing)by United States Department of Defense Advanced Projects Research Agency(DARPA) and the development of unmanned technology, the market of chip-scale atomic clock has attracted much attention. Stability is a key parameter of the performance of chip-scale atomic clock, which is affected by the accu-racy of temperature control, so a high accuracy temperature-control system is very essential to the stability of chip-scale atomic clock. A digital temperature-control system with high accuracy is designed,and its precision is 2mK. The test results show, the stability of chip-scale atomic clock is greatly improved from 7.57 × 10-12 to 4.99 × 10-12 , which is in a world level.; 国家自然科学基金; 4; 30-34; 37
