Multiple reignition makes the frequency and amplitude of overvoltage increase and might do harm to transformer coils by cumulative effects for its surge steepness.

多次重燃使得过电压频率和幅值均升高，会对变压器型设备绝缘造成危害。

Numerical simulation studies indicate that the adaptive filter is a powerful noise suppresser for correlated interferences, especially for those with amplitude changing and time delay.

数值模拟结果表明该波器对于相关噪声，尤其是有幅值变化和时的情况，有很强的抑制效果。

The maximum of B along elevation direction is closely under the central section of coil.The B of equiamplitude magnetic field is increased by increasing of the output current ...

幅高频磁场的磁感应强度随高频电源输出电流的增加而增加,磁场调幅处理能提高磁场内的磁感应强度,提高调幅波信号的幅值电压,可有效提高磁场内的磁感应强度。
