为了测量磁偏弧的电压、电流、电子密度及电子温度等参数的特性，搭建了电压电流测量系统，采用不锈钢棒状电极，在其间隙处加以磁感应强度为0、45和100mT的横向磁场，将电压升至约1500V，使电极间形成磁偏弧，测量不同条件下磁偏弧的电压和电流，同时采用光谱法对磁偏弧的光信号进行测量。结果表明：随着横向磁场的增大，电弧电压和电流增加，并在过零点处波形畸变；在光谱扫描特性中，电子激发温度和密度随着外加磁感应强度的增加而减少。以上研究结果为进一步研究水中电弧特性提供了参考。

The voltage, current, electronic density and electronic excitation temperature of arc blow were measured by using stainless steel electrode with 0 mT,45 mT and 100 mT transverse magnetic field between the gaps of elec trode with 1500 V. Magnetic arc blow was generated between electrodes, and its current and voltage under different conditions were measured. Signal is processed by spectrometry. The results indicate that： as magnetic intensity increases, the arc voltage and current will increase, but waveforms distort at zero crossing point; in the characteristic of scanning spectrometer, the electronic excitation temperature and density declines while magnetic field increases. The experimental results provide references for the further researches on arc discharge in water.
