结果表明：在高煤级煤早期阶段，形成于不同成煤环境的太原组煤与山西组煤的煤化特征仍有差异，在第三次煤化作用跃变之后这种差异逐渐缩小消失；高煤级煤分别以第三次和第四次煤化作用跃变为界，呈现出阶段性演化的特征，每阶段的演化机理有所不同；第三次煤化作用跃变中大分子结构的演化以芳构化作用主为，第四次煤化作用跃变则以强烈的环缩合作用占优势。

Applying the Large-scale multi-configuration Dirac-Fock wave functions, we calculated the parameters such as wavelength, oscillator strengths and excited energy for the transitions related to lightning spectra. The most important effects of relativity, correlation, and relaxation are included in the computational model. Comparison of the calculated results with experimental spectra shows that the spectra in plateau area have a distinctive characteristic. Beside the lines of lower excited state with n=3 in NII ions, transitions of NI and OI are increased, their excited energy is around 13~14eV, and there are rarely lines from OII ion.

The down core changes of Florisphaera profunda percentage content implied that the thermocline was shallower in glacial periods and deeper in interglacial periods, which might be the direct controlling factors of WPWP productivity changes. It is speculated that the glacial-interglacial fluctuation of the depth of thermocline was induced by the super-ENSO variation.

钙质超微化石下透光带属种Florisphaeva profunda百分含量指示的温跃层深度变化表明冰期温跃层浅、间冰期温跃层加深，这说明类ENSO式变化导致的冰期-间冰期温跃层深度波动可能是MIS7期以来暖池核心区古生产力在冰期高而在间冰期显著降低的直接控制因素。

In the northern part of the Okinawa Trough,at about 7.5-7.0kaBP of the early Holocene, this studied region was controlled by the continental shelf water, and at about 7.0aBP Kuroshio water combined with continental shelf water intensively, then the region was controlled by the intensified Kuroshio water with upwellings during 7.0-6.0kaBP; from 6.0-2.0ka BP the upwellings developed stably and the thermocline gradually declined: from 6.0-5.0 kaBP the impact of the upwellings mainly focused on the thermocline and much less on the sea surface, from 5.0-4.0kaBP the SST decreased because the sea surface was influenced by the cool water brought by the intensified upwellings; from 2.0-1.2kaBP, the upwelling declined and the SST increased consequently; since 1.2 kaBP the upwelling increased and the thermocline declined obviously.

冲绳海槽北部、九州西南海区，全新世7.5-7.0ka BP陆源物质影响明显， 7.0kaBP前后黑潮侵入并与陆架水强烈混合，7.0-6.0ka BP期间黑潮影响逐渐控制了该区，上升流开始发生，温跃层开始变浅；约在6.0-2.0ka BP之间上升流持续稳定发育，温跃层深度逐渐下降：6.0-5.0ka BP上升流影响作用于温跃层但对表层影响较小，5.0-4.0ka BP海水表层温度受上升流冷水影响降低；而约2.0-1.2ka BP，上升流减弱，海水表层温度回升；近1200年来上升流加强、温跃层深度减小的趋势更加显著。
