- background magnetic noises 背景干扰磁场
- Using the strong background magnetic field produced by effective electromagnet and the catching surface to produce high magnetic field gradient makes the separation of micro-grade material possible. 利用有效电磁体产生的强背景磁场和能产生高磁场梯度的捕集表面,使得分选微米级的物料成为可能。
- It is showed by the experimental results that the influence of the background magnetic field is mostly eliminated, the precision is improved, and the stability of the gradiometer circuitry is good. 试验数据表明,背景磁场的干扰得到有效的消除,从而提高测量精度,且电路的稳定性能良好。
- Because read heads based on EMR use nonmagnetic materials, they would not suffer from magnetic noise limitations. 由于EMR读取头用的是非磁性材料,所以不会受到磁杂讯的限制。
- EMR read heads would have many good features in addition to the high data densities and low magnetic noise [see table above]. 除了资料密度高及磁杂讯低之外,EMR读取头还有许多优良特性(见上表)。
- Digital Sound: USB port and digital signal processor to keep digital sound clean, eliminating electro - magnetic noise from the audio you hear. 数码声音:USB接口和数字信号处理器使数字声音干净,消除电-磁噪声音频你听到。
