| 根据1986—1990中美热带西太平洋海气相互作用8个航次合作综合调查资料，分析了1987年10月赤道中西太平洋165°E（10°N－6°S）次表层水形成溶解氧最大值的原因。1986－1987年E1Nino衰退时期，该海域赤道附近在E1Nino强盛时期下沉的次表层水开始回升，短时期内形成了类似于中、高纬度海域的理化环境，使浮游生物在混合层内聚集生长，最终导致溶解氧含量在次表层出现最大值和过饱和含量。 |

| Abstract: |
| Based on the comprehensive investigation results of eight cruises of US-PRC TO-GA, we have analysed the mechanism of the maximum of dissolved oxygen occurrenced in sub-surface water at 165°E Tropical Pacific Ocean (10°N - 6°S) from 1986 to 1990. The sub-surface water in the sea area near the_ equator, which fell during the prevail of El Nino, had gone again during the decline of E1Ni5o in 1986 - 1987. As a result, the physical-chemical environment occurrenced in this area was similar to that in the middle latitude or high latitude in a short period. Plankton grew considerably in the mixed layer, which caused the supersaturation or maximum of dissolved oxygen occurrenced in the sub-surface water of that area. |
