接地极性 [jiē dì jí xìng]
polarity of ground
- 如果孩子不接地并象西方那些孩子一样倒转极性，电流增大了再增大，直到孩子是如此神经紧张，在教室里东奔西跑，或如此烦躁，不能安静地坐着并集中注意力。
If the children are ungrounded and reverse polarized such as most white children in the West, the electricity builds and builds until the child is so nervous they wish to run around the classroom, or so fidgety that they cannot sit still and pay attention.
