All of the red tide incidents in South China Sea since 1980 ~2004,the spatial and temporal distribution of the events,and the change characteristics of the average duration of the red tides were analyzed.

收集整理了自1980~2004年的南海历次赤潮事件,并对这些赤潮事件在时间和空间的分布特征以及赤潮持续时间长度的变化特征进行了分析;探讨了形成南海赤潮时空分布特征和持续时间长度变化的可能原因。

The temperature of the reactor was lowered from 55℃ to 20℃ in case of heating failure and the duration in the low temperature were 1,5,12 and 24h respectively.

模拟由于加热失败导致温度从55℃突降到20℃(室温左右),且在20℃时持续时间分别为1h、5h、12h和24h,对高温厌氧消化处理城市有机生活垃圾工艺的影响进行了实验研究。
