Such algal blooms are not only harmful to people and animals but can also trigger dead zones in the lake-areas in the water so devoid of oxygen that they cannot support aerobic life.

Dead zones form when big blooms of phytoplankton at the surface trigger large quantities of organic matter, which then sink to the bottom.

当水面上大量爆发的浮游植物触发产生大量的有机物质，而这些有机物质随后下沉到水底的时候，死亡带就形成了。

The threshold detector is similar to a Schmitt Trigger in that it is a latch circuit with a large dead zone.

阈值检测器就是一种回差范围较大的锁存电路，与施密特触发器相似。
