摘要： A free liquid helium volatilization superconductive magnetic suspension device includes a low temperature container, a refrigeration, a cold screen, a liquid helium container, a superconductive rotor, a suspension coil, a rotor chamber, a liquid tube, a condenser and a pole-axis displacement sensor. The heat generated by the wires of the suspension coil can be prevented transferring to the liquid helium container by the room temperature current lead joint, the high temperature superconducting current lead joint and low temperature superconducting current lead joint. Therefore the volatilization of the liquid helium in the liquid helium container can be reduced. The status of free liquid helium volatilization in the liquid helium container can be reached through refrigeration cooling condenser to liquefy the helium. The device needs not to be input the liquid helium time after time and can run independently for a long term.

摘要： A low-temperature superconducting device for measuring gravity, includes a low-temperature container, a cryocooler, a rotor chamber, a superconducting rotor, an upper levitation coil, a lower levitation coil, an upper electrode, an intermediate electrode, a lower electrode, a magnetic shielding chamber and a superconducting quantum interference device. By cooling the whole low-temperature superconducting device using a cryocooler, the intermediate electrode disposed in the body of the magnetic shielding chamber will generate an output voltage when the superconducting rotor is displaced due to a change of gravity. Thus, the superconducting quantum interference device can make the superconducting rotor return to the central balance position by adjusting the operating current of the upper levitation coil or the lower levitation coil. A change of gravity can be determined based on the operating current fed back to the upper levitation coil or the lower levitation coil.

摘要翻译：一种用于测量重力的低温超导装置包括低温容器，低温冷却器，转子室，超导转子，上部悬浮线圈，下部悬浮线圈，上部电极，中间电极，下部电极，磁屏蔽室和超导量子干涉装置。通过使用低温冷却器冷却整个低温超导装置，当超导转子由于重力的变化而移动时，设置在磁屏蔽室的主体中的中间电极将产生输出电压。因此，超导量子干涉装置可以通过调节上部悬浮线圈或下部悬浮线圈的工作电流使超导转子返回到中心平衡位置。可以基于反馈到上部悬浮线圈或下部悬浮线圈的工作电流来确定重力变化。
