In virtual ground mode, the high channel will source and the low channel will sink current.

在虚拟接地模式中，高通道将提供电流，低通道将吸收电流。

If the voltage is removed for more than 90 msec, the electronic will start to sink current 10 msec after the application of voltage as usual.

如果电压移除大于90毫秒﹐电子负载会照例在输入电压后10毫秒才拉电流。

Hopefully the current oil slick will harden and sink to the ocean floor before it has a chance to make landfall in Louisiana over the next few days.

希望目前水面浮油能够在接下来几天到达路易斯安那州之前尽快凝固并沉入海底。
