The system must be cooled to 50 millikelvins to minimize thermal vibrations, which interfere with the cantilever’s magnet-induced displacement signal.
其必须冷却到50微K，以尽可能的减小热振动，因为热振动会干扰悬臂的磁场，而这个磁场又是产生位移信号的关键。
A current can also be induced by constantly moving a permanent magnet in and out of a coil of wire or by constantly moving a conductor near a stationary permanent magnet.
让永久磁铁在线圈中进出运动或让一个导体在固定的永久磁铁附近的区域移动，也会产生电流。
The dual magnet circuit is designed with the magnets. The magnetic induced intensity in the duct is raised to 0 78T. The principle experiment is performed by the jetting fluid of the rocket engine.
设计了双磁回路，通道内磁感应强度提高到0．78T，用火箭发动机的射流作为工作源，进行了发电原理实验；
