When initial NO3--N was leached, the correlation coefficients between soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation with raygrass nitrogen uptake were decreased to 0.613 and 0.607, respectively, and both reached 5% significantly level. However, the correlation coefficients between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogen uptake were raised obviously, and all reached 5% and 1% significant level.

以不包括土壤起始NO3--N盆栽试验植物吸氮量为参比,通气培养前CaCl2淋洗起始NO3--N和起始矿质氮与五期黑麦草地上部氮素累积量间的相关性尽管有所降低,但相关性仍达5%显著水平,相关系数分别为0.613和0.607;而通气培养30周矿化氮素、土壤起始矿质氮+通气培养30周矿化氮素、N0及N0+起始矿质氮与五期黑麦草地上部吸氮量的相关系数却明显提高,相关系数分别为0.718,0.782,0.688 和0.640,均达5%或1%显著水平。

The results indicated that when initial NO3--N was not leached, soil initial NO3--N and mineral N extracted by CaCl2 before aerobic incubation were closely related with raygrass nitrogen uptake, the correlation coefficients were 0.856 and 0.862, respectively, both reached at 1% significant level. When initial NO3--N was leached, it was no good relationship between mineralizable N extracted by aerobic incubation, soil initial mineral N and mineralizable N extracted by aerobic incubation, N0 and soil initial mineral N and N0 with raygrass nitrogrn uptake, the correlation coefficients were 0.410, 0.553, 0.492 and 0.419, respectively, indicating that the poor effects of mineralizable N on reflecting soil N capacity were influenced and disturbed by initial nitrate.

以包括土壤起始NO3--N盆栽试验植物吸氮量为参比,通气培养前CaCl2所淋洗起始NO3--N和起始矿质氮与5期黑麦草地上部氮素累积量密切相关,相关系数分别为0.856和0.862,达1%显著水平;与此相反,通气培养30周所矿化氮素、土壤起始矿质氮+通气培养30周矿化氮素、氮素矿化势(N0)及N0+起始矿质氮与5期黑麦草地上部氮素累积量间无显著相关关系,相关系数分别仅为0.410、0.553、0.492和0.419。

Maturity of Lower Cretaceous source rock, researched by the authors, is closely relative to the deposition thickness of the Tertiary and the Quaternary. It shows that source rock at the depth of 4,000-4,400m is low mature, and 4,400-5,200m is in the peak of oil generating. Correspondingly, the source rock of the Zhonggou Formation is immature; the Upper Xiagou Formation is low mature; and the Lower Xiagou Formation and the Upper Chijinpu Formation are in the peak of oil-generating; and the Lower Chijinpu Formation is at the stage of generation of condensate-wet gas with high maturity. There is no source rock reaching the overmature stage of dry gas at present.

可溶有机质转化率、镜质体反射率、热解、生物标志物特征等参数表明:青南凹陷中部的下白垩统烃源岩生油门限深度为4000m(相应的镜质体反射率为0.65%),埋深4000~4400m为低成熟阶段,埋深4400~5200m为成熟生油高峰阶段,因此中沟组烃源岩未成熟,下沟组上部烃源岩低成熟,下沟组下部和赤金堡组上部烃源岩处于成熟生油高峰阶段,赤金堡组下部烃源岩处于高成熟的凝析油—湿气阶段,目前尚无烃源岩达过成熟干气阶段。

And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.

When pump starts, the lower impeller lifts the solution up step by step. And the extreme centrifugal force from the enlarged higher impeller stops the solution as it entering the higher impellr. At the same time, the full solution in the chamber stops the air mixed with the solution in the chamber to go down. This way masterly eliminates both big problems of vertical sealless pump, overflow at high pressure and bubbles at big flow.
