    The Study on Microwave Power Frequency Shift in  ̄(87)Rb Atomic Frequency Standard and Its Controlling Methods
    原子频标中微波功率频移的研究及其控制方法
短句来源
    The relation between microwave-power frequency shift in 87Rb atomic frequency and microwave power is studied experimentally. Results indicate that microwave-power and microwave power display linear relation and coefficients of microwave-power are always positive. The precision of measured data of relative microwave-power is 1×10 -11.

  rb
The samples were characterized by XRD, BET, DTA-TG, UV-Vis, and their photocatalytic properties were evaluated with two model pollutants, methylene blue (MB) and rhodamine B (RB), at room temperature.
      
For three tested samples, under UV illumination CCT01 has the highest activity for MB photocatalytic degradation, while in the case of RB, CCT02 is the most active photocatalyst.
      
Under visible light illumination, CCT005 has the highest activity for both MB and RB photocatalytic degradation.
      
Seven pore water samples were analyzed for their anion (Cl-, SO42-, Br-, I-) contents, cation (Na, K, Ca, Mg) contents and trace element (Li, B, Sr, Ba, Rb, Mn) contents.
      
However, elements of Fe, Co, Zn, Ni and Rb may catalyze the organic matter maturation.

For miniaturizing the optical-microwave unit of 87Rb atomic frequency standard, various possible schemes of optical pumping devices with two bubbles are investigated and discussed.

本文从铷原子频标物理部分小型化的目的出发,测量并讨论了各种可能的两泡式光抽运方案。

In this paper, a new device for eliminating the collision shift, light shift and microwave power shift in the 87Rb atomic frequency standard is presented. It would greatly improve the performance of this standard.

本文提出一种在~(87)Rb气泡式原子频标中消除碰撞频移、光频移和微波功率频移的新方案,有可能大大提高它的性能。

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.

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。
