You may not be aware of this but the chassis of your vehicle is actually connected to the negative terminal of your battery. So your car is actually negatively charged.
你可能有所不知，你车的底盘其实连接着电池的负极，所以，你的车其实是带负电荷的。
Think, for instance, what happens on the it side when, as has happened so often lately, a domestic facility escapes negative refining margins by conversion to a terminal facility.
例如，考虑一下it方面发生的这样一个场景(最近尤其常见)，一个内部设备通过转换成一个终站设备(terminal facility)避免了炼油毛利变为负数。
Before connecting this unit, please make sure that the input and output terminal, and the positive and negative polarities of output terminal are on the right position respectively.
使用时请注意区分输入端与输出端，以及输出端的正负极性，核对无误后才能通电；
Conclusion: the terminal QRS distortion of the initial ECG may have affinity to the early prognosis in AMI, and can be used as one of the factors in predicting the negative prognosis.
结论AM I心电图QRS波终末变形与早期预后有密切关系，可作为负性预后的指标之一。
The unipolar transistor has a negative polarity or a positive polarity in accordance with the first terminal or the second terminal electrically connected to the unipolar transistor.
单极晶体管根据第一端子或者第二端子电连接于单极晶体管而具有负极性或者正极性。
Finally, 3-terminal BNRT with different structure and process parameters is simulated, and the influence of device structure and process parameters upon negative characteristics is summarized.
最后，对不同结构和工艺参数的三端bnrt进行了模拟，总结出器件结构和工艺参数对负阻特性的影响。
Based on this, a Two-terminal Bidirectional negative resistance Device (TBNRD) is fabricated and the theory of the negative resistance is studied.
在此实验基础上研制得到一种双向两端S型负阻器件(TBNRD器件).本文还对该器件产生负阻的原因进行了理论分析。
