摘　　要：氢脉泽是一种中、长期稳定度最高的原子频率标准。其中原子磁态选择器的改进设计可以改善氢脉泽的工作参数及其体积与重量,从而改进氢脉泽的品质与工作寿命等,同时也可以改进氢脉泽的长期性能,并给出了磁态选择器的设计与实验结果。The atomic hydrogen maser is the most stable frequency standard generally available today for all but the shortest measuring time interval. The design improvement of the magnetic selector benefits the improvement of the hydrogen maser＇s working coefficients and greatly decrease its volume and weight. Some useful relations to the design and experiment results of the atomic beam optics are given and important factors are discussed which must be taken into account for optimizing the atomic beam optics while improving the long-term performance .
