The polarity of the ends of the open-circuit conductor may then be deduced . 这样就可以断定开路导体两端的极性。
It is not possible to try to salvage or change the polarity correctly by charging . 试图补救或通过充电的方法把极性改过来是不可能的。
There are miscellaneous tools, pliers, putty knife, polarity stamps, battery stamping or coding equipment, lead cutters . 有各种工具、手钳、油灰刀，极性印戮、电他标记打印或编号机、铅切刀。
Either glyme, diglyme, nitromethane, or other suitable solvents of similar polarity may be used as the solvent component . 乙醚、乙二肟、二乙二肟、硝基甲烷或类似的适当的极性溶剂，可用作溶剂。
Ether, glyme, diglyme, nitromethane, or other suitable solvents of similar polarity may be used as the solvent component . 乙醚、乙二肟、二乙二肟，硝基甲烷或类似的适当的极性溶剂，可用作溶剂。
When the sun's rotation sweeps this warped surface across the earth, we detect sudden changes in the polarity of the magnetic field . 当太阳的自转使这个波浪形间隔面扫过地球时，我们就会探测到磁场极性的突然反转。
Wiring at switch connected up with incorrect polarity 开关掣的极性接驳错误。
