reversal of polarity

Mechanism, characteristic and efficiency for the electrodialysis reversal ( EDR) process are presented in this paper. Parameters of the EDR process have been studied, and continually run in more than 2000 hours at given periodic reversal of polarity ( 3-4 times per hour).

本文简要介绍了EDR工艺的机理、特点和效果，进行了EDR工艺的参数研究，并以一定的倒极周期（每小时3&4次）连续运转2000多小时。

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.

now due to the reversal of polarity there is an opportunity for those who are ascending to win win win;

现在由于极性的翻转对那些正在提升的人就有机会去赢赢赢；

what is reversal of polarity?

什么是极性的翻转？

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。

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。
