tide cycle

The rising bacteria levels are due to an increase in heat that causes an abundance of algal blooms. Red tide causes a toxic cycle that can cause serious illness in humans and kill water life.

持续高温导致水体中藻类和细菌大量繁殖，而后产生的赤潮现象更会导致恶性循环，也会导致人类疾病并威胁水中其他生物。

However, waterlogging for ( 8 h) in every tide cycle is critical for normal development of seedlings. K.

秋茄幼苗生长的临界淹水时间是每个潮水循环淹水8h。

So a new concept that the time-dependent sediment transport capacity is proposed, which means sediment transport capacity varies with tidal velocity and water level in half tide cycle and it is a function of time.

为此提出时变挟沙能力的新概念，即水流挟沙能力在半潮周期内随潮流速和潮位同步变化，是时间的函数。

Under calm weather period, the quantity of sediments deposited during a complete spring-neap tide cycle is higher at the northern, southern parts than the central parts of the tidal flat in the study area.

在平静天气条件下，一个潮周期沉积量，在崇明东滩南、北端大，中部沉积量较少。

In order to simulate the effect of tide-generating force of the sun and the moon, a cycle stress is loaded superposing on a basic axial load level.

为了模拟日、月潮汐力对地球的加载和卸载作用，在某一固定水平的轴向压力作用下，叠加上循环载荷。
