【摘要】 本文报导了利用分离型吸收泡制成的铷频标中有关光频移、微波功率频移、壁移等问题的实验研究。结果表明,光频移可以减小一个数量级;但由于泡壁石蜡涂层的放气使得微波功率频移不能消除,壁移的温度系数也较大。更多还原

【Abstract】 Some experimental results on the problems of light-shift,microwave-power-shift and wall shift of 87Rb frequency standard with separated resonant cell are reported.Conclusions derived from them are.(1)the light-shift can be reduced by 15 times;(2)the microwave-power-shift can not be eliminated due to the degassing of the paraffin coating; and(3)the temperature coefficient of the wall shift is comparatively large.更多还原
