The mechanism was similar to the equivalent barotropic warm core structure. The Conditional Instability of the Second Kind was the primary mechanism of development and maintenance for MCSs in case 2005. As the MCSs intensified and persisted, the latent heating was highly efficient in producing significant enhancement of Mei-Yu front systems. The LLJ intensified by Coriolis acceleration of ageostrophic wind was induced by the effect of latent heat release. The LLJ and the effect of latent heat released reinforce each other in convection system through a positive feedback process.
综合而言,2005年个案中梅雨锋面结构为垂直近乎不倾斜的浅系统,槽线系统不明显,锋面水平温度梯度微弱,低层具有强水平气旋式风切,较似正压系统,个案中MCS发展及维持机制,主要是透过CISK 过程来维持;其过程是由於低层锋面带上之辐合激发对流发展,对流潜热释放造成局部气压梯度增强,因而增强地转风;而潜热释放亦有利低层辐合之增强,产生非地转风,再透过科氏加速增强西南风,使LLJ增强,形成一正向的回馈作用。

Tectonic subsidence play dominant role in their geometric shapes, basin fillings, sequence evolution and sediment distribution in the Wushi Sag. Outline of the sequences are in shape of box-wedge or sheet-wedge and boundaries of sequences are varied from bilateral fault to monoclinal fault overlap, so that the sequences show distinct semigrabens which overlay in different ways. Seven sequences were formed in different stage of tectonic evolution. The sequence of SQ1 formed in initial rift stage and deposited alluvial sequence. Sequences SQ2-SQ4 developed in intense rift stage and sediment lacustrine sequence. Sequences SQ5-SQ7 formed in late period of rift before thermal subsidence and deposit mere and delta sediment. The place adjacent to the synsedimentary fault is the subsidence center and depocenter; meanwhile, controlling fracture migrates in horizontal made subsidence and sedimentary center of the sag changed.
构造沉降是控制层序几何形态,充填叠置方式、演化及沉积体系分布的最重要因素:凹陷由多个半地堑在不同层序发育时期以不同方式叠置联结而成;受断层控制,层序外部形态有箱状-楔形、楔形-席状披覆型,边界终止方式有双断终止型、单断终止超覆型;不同构造演化阶段层序内部充填的沉积体系各具特征,初始断陷阶段的SQ1沉积冲积层序,强烈断陷阶段的SQ2-SQ4充填湖相层序,晚期断陷阶段SQ5-SQ7内部充填浅湖和河流三角洲沉积;同沉积断层陡坡带沉降迅速、可容纳空间快速增长,是凹陷的沉积和沉降中心,断陷期主控断裂活动时间和空间的变化导致了凹陷沉积和沉降中心的迁移。

When the gas flux is constant, the ratio of reduced resistance is improved with the increase of the water stream velocity. However, the relationship between the gas flux and the ratio of reduced resistance is more complex. When the water stream velocity is constant, if the gas flux is small in contrast, the effectiveness of reduced resistance is not obvious. But when the gas flux increased, the jetted gas will form """"archform"""" which will augment the shape resistance. In this condition, resistance could not be reduced and could even be increased, if the gas flux continues to be increased. So that there needs setting a baffle called step, which introduces the jetted gas into the turbulence boundary layer. In this case, the shape resistance may be fairly great. Besides, the waterline of model has also some effect on the ratio of reduced resistance, which acts on the size of wave. If waterline is deep, the wave could not affect the deployment of microbubble layer, so there is almost no effect on ratio of reduced resistance. However, the wave would affect distributing of microbubble layer under the model so that the gas could leak out from the two sides of model and directly affect the ratio of reduce resistance if the waterline is very small. Whether installing the dashplate or not has also the great influence on the effectiveness the ratio of reduced resistance. From the results of experiment, conclusion is that adding dashplate will greatly improve the effectiveness of reduced resistance.
当喷气量一定时,水流速度增大,减阻率提高;喷气量与减阻率之间的关系比较复杂,速度一定时,如果喷气量较小,减阻效果就比较差,但当喷气量增大的话,喷射出的气体就会形成一个&拱度&,增加了船模的形状阻力,在这种情况下最好采取断阶喷气,把气体引入到湍流边界层中,在这种情况下,船模的形状阻力比较大;船模的吃水对减阻率也有一定的影响,主要表现在波浪大小上,如果吃水较深,波浪影响不到微气泡层的分布,对减阻率不会造成太大影响,如果吃水较浅,波浪就会影响到微气泡层在船模底部的覆盖情况,可能会有部分微气泡从船模两侧泄漏,这样就直接影响到了减阻效果;是否安装压浪板,对减阻率也有较大的影响,从试验结果可以看出,在船模尾部加设了压浪板时,减阻效果明显得到改善。

From the early study of the pathogenesis of pre-eclampsia people have found its association with immunological function . In 1986 Ellis et al[1] had found that the extravillous chorionic cytotrophoblast contacting with the maternal tissue expressed high levels of Human leukocyte antigen-G, a major histocompatibility tissue-specific antigen . Extravillous chorionic cytotrophoblast with high levels expression of HLA-G proteins can invade the maternal deciduas and the maternal spiral arteries by displacing the endothelial lining and destroying most of the musculoelastic tissue of these arteries .
早期研究开始,许多学者即发现其与免疫学有密切关系,至1986年Ellis等[1]发现人类白细胞抗原(human leukocyte antigen,HLA) G分子高度表达在绒毛外滋养层细胞( extravillous cytotrophoblast,EVCT)上,即浸润至子宫蜕膜层甚至达子宫浅肌层以及子宫螺旋动脉内皮层,与母血及子宫组织直接接触的滋养细胞,这种独特的组织分布提示HLA-G分子在母胎免疫耐受方面起重要作用。

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。

The characteristics of sequence development, source reservoir - seal assemblage and types of hydrocarbon reservoir for each sequence were discussed in detail. The dark colored shale of deep lacustrine facies in the transgressive system tract of SⅡ sequence deposited around the maximum flooding surface is the main source rock in this area. The shale of shallow lacustrine facies in the TST of SⅢ sequence around the MFS is the most important regional seal rock.
结果表明,该区古近系可划分为SⅠ,SⅡ,SⅢ和SⅣ4个层序,分别对应于房身泡组、沙三段、沙一段沙二段和东营组。SⅡ层序水进体系域最大湖泛期沉积的半深湖深湖相暗色泥岩是研究区的主力烃源岩系;SⅢ层序水进体系域最大湖泛面附近的浅湖相泥岩是最重要的区域盖层。
