Now suppose that you want your Data View to include only current products where the units on order equals zero, so that you can decide whether to order additional units.
现假设要数据视图仅包含已订购数量等于零的当前产品，以便决定是否要订购额外数量。
When grounding fault happens at the time when current is zero, the transient value is too small, in order to prevent it, the paper brings forward the current increment method to select faulty line.
为防止在电流过零点附近发生的接地故障时的暂态量太小，论文提出利用电流增量进行故障选线。
In order to prevent the primary current from flowing in the reverse direction during zero state, two diodes are added in series with the lagging switches respectively.
为了使一次电流在零状态时减小到零后不再反方向流动，在两个滞后管中分别串入一个二极管。
