polarity reversal

In essence each polarity reversal has pressed her into the next level of dream.

本质上,每个极性逆转,都已经将她推入下一级别的梦想.

Elongating the time of polarity reversal can reduce the field strength under polarity reversal.

延长极性反转时间可降低极性反转时的场强。

Suitable for using in polarity reversal circuit. Such as signal coupling circuits and speakers , etc.

适用于极性反转回路及须急速印加逆向电压之回路.

The intensity of palaeomagnetic field, the proportion and frequency of palaeomagnetic polarity reversal, and the rate of true polar wandering may display the periodic changes in the geological history and are closely related to the opening and closing, and may be restricted to the global factors.

古地磁场强度、古地磁场极性倒转比例、古地磁场极性倒转频率和真极移速率在地史上均呈周期变化，与开合构造关系密切，同受全球性因素制约。

Uses the simplex winding polarity reversal method to realize the speed transformation.

采用单绕组变极方法实现速度变换.
