报道了一种非接触式测量悬浮样品电阻率的方法。该技术利用了异步感应电机的原理，通过对样品施加旋转磁场来测量感应扭矩。通过实验验证了样品大小与感应扭矩的关系，证明了感应扭矩与样品半径的5次方成正比。在此基础上，测量了固体锆片的高温电阻率，并与文献数据进行了比较，符合较好。
A non-contact technique to measure the electrical resistivity of levitated samples is reported. The technique utilizes the principle of the asynchronous induction motor, measuring the induced torque by applying a rotating magnetic field to the sample. Relation between sample size and induced torque was experimentally checked with aluminum samples and proved that induced torque is proportional to the fifth power of the sample radius. Based on this result, the electrical resistivity of solid zirconium at high temperatures was measured and showed a good agreement with literature data.
