pulse polarity meaning in English

脉冲极性

On the basis of the theory and the experiment , the paper has synthetically analyzed the anti - interference characteristics of the hardware method ( differential balance ) and software method ( digital filter ) . the paper has presented that these two methods have some disadvantages respectively . based on this fact , a new method has been presented . hardware method can be use to restrain periodical interference , and software method can be use to discriminate pulse polarity
从理论和试验两方面，综合分析了硬件措施(差动平衡法)和软件措施(数字滤波法)抑制干扰(包括周期性和脉冲性干扰)的方法和特点，指出了两种方法各自存在的缺点，在此基础上提出了用硬件方法抗周期性干扰，用软件抗脉冲性干扰的新方法，并通过试验证明，该方法可以抑制周期性干扰，有效地鉴别出外部干扰信号和内部局部放电信号。
