建立了高频原子波导模型，分析了铷冷原子在该波导内与磁场的相互作用势。高频波导线圈输入电流,在线圈中心轴线区域的势阱深度为mK量级，在线圈的径向能对温度为100 μK左右的冷原子实现囚禁。通过分析可知改变输入波导线圈的输入电流大小,可改变势场的大小。计算了进入高频原子波导的冷原子和波导磁场产生相互作用束缚力的大小。在波导轴线中心区域，原子受到的束缚力较大，最大为1.7×10－23N，为原子所受重力的10倍。

The model of a radio-frequency waveguide was built. The interaction potential of Rb cold atoms with the magnetic field in the radio-frequency waveguide was analyzed. When an electric current is input into the coils of the waveguide, the potential depth at the center axis of the coils is about 1 mK. Such kind of waveguide can confine the cold atoms whose temperature is 100 μK along the radial direction and guide them along the axial direction. The potential field in the waveguide changes as the input current changes. The force that the waveguide exerts on the atoms along the axis of the waveguide is 1.7×10－23N, tenfold the gravity of a Rb atom.
