1·From sparking plug lead, reverse polarity protected.

从引发插件铅，反向极性保护。

2·American SEG defines seismic record polarity as SEG normal polarity and SEG reverse polarity.

美国SEG协会把地震剖面的极性规定为SEG正常极性和SEG反正常极性。

3·When inputs to most JFET op amps exceed the common-mode range for the part, the output may reverse polarity.

当大部分JFET运放的输入超过它的共模范围时，输出可能发生极性翻转。

4·The reverse polarity protection prevents destruction of the sensor by a reversal of the polarity of the voltage supply.

反向极性保护防止了一对电源电压极性反转传感器的破坏。

5·It could self-recover after the breakdown is fixed, except for Reverse Polarity Protection, which the fuse has to be replaced.

它可以在自我故障后恢复，除了反极性保护，而保险丝更换。

6·Another advantage the Global electronic switches possess is reverse polarity protection to prevent damage from miswiring the sensors.

另一个优势是全球电子开关具有反向极性保护，以防止错接传感器损坏。

7·All hardwired connections to LED fixtures shall be reverse polarity protected and provide high voltage protection in the event connections are reversed or shorted during the installation process.

所有与LED装置硬连线的连接须采取逆极性的保护，在这些连接被扭转或缩短的安装过程中，须提供高压保护。

8·If a cell does get fully drained, though, it can go into a state known as polarity reversal, in which the surrounding good cells drive the bad one in reverse.

如果电池没有完全耗尽，便会进入一种称为极性颠倒的状态。这种状态下，周围具有电量的电池会反过来推动电量很少的电池工作。

9·This is a sign that the many falls in vibration are now upon the reverse swing of polarity within the Great Central Sun.

这是大中枢太阳中诸多次振动下降后向极性之反向提升的征兆。

10·The end electrical field distribution under polarity reverse test voltage of valve winding in converter transformer is calculated. The results are analyzed.
