| 1. | Hence only one line of force can pass through each point of the field .
因此电场中任一点只能通过一条电力线。 |
| 2. | Arrowheads on the lines indicate the direction in which the tangent is to be drawn .
电力线上的箭头表示所要画的切线方向。 |
| 3. | No lines of force originate or terminate in the space surrounding a charge .
在电荷周围的空间内，并没有电力线的起点或终点。 |
| 4. | At each crossing of an equipotential and a field line, the two are perpendicular .
在等位面与电力线的每个交点，两者是垂直的。 |
| 5. | In an uniform field, the lines of force are straight parallel, and uniformly spaced .
在匀强电场中，电力线是平行的直线，其间隔是均匀的。 |
| 6. | Lines of force can begin or end inside a region of space only when there is charge in that region .
只有当这一空间区域内有电荷存在时，电力线才能发自或终止于这一空间区域。 |
| 7. | Muck settled on power lines and transformers, shorting everything, putting us out of action for a week .
污泥碎石落在电力线和变压器上，把一切都切断，使得我们停产整整一个星期。 |
