In the dry months of the year a simple ferry crosses a river in southeastern Sierra Leone; a car-carrying pontoon propelled by men with notched wooden sticks that lock to the guiding cable.

在每年干旱的几个月里，有一条简易渡轮往返于塞拉利昂东南的河流两岸。人们通过开过槽并固定在导索上的木棒推进能承载车辆的浮筏。

They come with a clothes clip (reduces cable strain so they won't yank out), a carrying case and comfortable rubber-dome earbud tips in several sizes.

耳塞同时带有一个小衣夹(减少耳塞线紧绷以及猛拉过度)，一个便携盒与各个尺寸的舒适橡胶圆套头。

An unbalanced line is generally a single-conductor shielded cable with the center conductor carrying the signal and the shield at ground potential.

对于非平衡式信号线来说，就是一根被屏蔽了的信号线，这个中心信号线传输信号，且相对于地电势。
