As the surface altitude increases, the water level and the imbedded water level decrease, and is lowest in Betula ovilifolia－Carex schmidtii－Sphagnum palustre community, which may be firstly caused by the distribution of the hummocks of Sphagnum palustre, which is powerful in holding water, and this has cushion function on the change of water level; On the other hand, it may be caused by it's position near the hill, the runoff from the hill may supply the district, so that the change extent of water level at a certain extent minishes.

随着地表相对高程的增加，水位变化幅度逐渐变小，在油桦－臌囊苔草群落中最小，这一方面可能与泥炭藓丘的分布有关，泥炭藓具有较强的饱水和持水能力，对水位的变化具有一定的缓冲作用；另一方面是由于该区靠近山地，山坡上形成的坡面径流可能对该区域有所补给，这也在一定程度上减小了水位的变化幅度。

当把传水辊手不静压上串水辊尝试不张力时，发掘两者之间的不张力不小了不面，而它们都是经过镀铬的软铁辊，过不小的不张力会使传水辊像架在串水辊上不同，导致传水辊轴脚与水斗电机传不静齿轮不匹配，间隙较不小，运转时不离会有些颤不静。

The ionic space charge in the micro-voids of water tree will produce a period vibration by AC voltage stimulating. Under superposition voltage, the vibration can impel the ion penetrating into the tiny crackle between micro-voids of water tree and lead to a change in the conductivity of water tree. With this the ultra-low frequency spatial current signal of the water tree would be emerged in detecting circuit. The polarization and depolarization of the polar end-group of the PE formed in water tree developing will also contribute to this special signal.

本文分析认为，水树枝中的离子型空间电荷在几种电压共同作用下会发生周期性振动，这种振动会促使水树枝中的导电离子在较低的叠加电压激励下进入连接水树枝微孔的微裂纹，微裂纹导通不仅导致水树枝的电导发生变化，而且在检测回路中会有水树枝老化超低频特征信号电流产生。

This thesis deals with oil-water flow rate measurement using a venturi and develops a differential pressure-based two-phase flow rate measurement model, which does a terrific job with the use of a water fraction device. Meanwhile, Coriolis flow rate meter is also studied in the oil-water two-phase flow measurement and a SVM-based single-phase flow rate prediction method is proposed, realizing the prediction of single-phase flow rates. To overcome the disadvantages of both venturi and Coriolis flow meters, a double parameter measurement method is put forward, which combines the two meters and solves the problem of oil-water flow rate measurement. Last but not least, on the basis of the study of two-phase flow, a device for the separation of gas and liquid is designed and realizes the flow rate measurement of three-phase flow as oil, gas and water.

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.
