摘　　要：本文是根据地质矿产部“海洋4号”船于1986~1989年在太平洋中部调查采集到的洋底沉积物,通过高效多用途压滤机压取的软泥水,在测试获得的大量第一性资料基础上撰写的。首次系统全面地揭示了该区软泥水化学成分的基本特性和时空分布规律。依据软泥水所在介质环境特点和物质成分分析,结合水岩作用模拟试验和计算机技术等手段,剖析了软泥水的后生变化过程,提出了软泥水化学成分在早期成岩阶段以贫有机质、弱碱性强氧化环境为背景演化的新模式。The paper is completed on the basis of researches and analyses to the ooze water squeezed by the highly-efficient versatile squeezer from the ocean-floor sediments, which were obtained by the ship 'Ocean No 4' of the Ministry of Geology and Mineral Resources, PRC during its voyages to the central part of the Pacific Ocean for oceano-geological investigations from 1986 to 1989. For the first time, it systematically reveals the fundamental properties of chemical components and temporal-spatial distribution of ooze water within the area, analyses the secondary change process of ooze water and puts forward a new evolution model of chemical components of ooze water during the early diagenesis stage in the organic-poor, weak akaline oxidizing environment based on the analyses to medium environment characters and material components, and the simulation tests of water-rock process as well as the computer technique.
