Sediment from river is not the main source of the Rushan Bay now any more ,which leads to the change of balance of sedimentation power. Sediment will transport because of the drive of hydrodynamic elements in macroscopic view .Direction of suspended load is basicly the same as tidal current .Flood tide makes suspended load transport to tip of the inner Bay and to the Mouth in exterior Bay .The direction of longside sediment transport in two sides of the Mouth mainly focus in the Mouth .Because the coastline along the exterior Bay is very meandering and it belongs to the type of bedrock ,besides some sediment going into the inner Bay ,so actual net sediment discharge rate is less than calculation .It develops an ebb delta out of the Mouth and forms tidal sand ridge ,tidal washing canal ,barrier bar and marine physiognomy ;The result of model simulation disclosures that differences of sediment erosion and siltation between single tidal action and wave-current action are very big .From the analysis of sediment composition、sediment sources and stability of beach and ridge ,this article gets the conclusion that the channel has the possibility to silt ,though the course maybe very slow.
通过分析研究文章得出如下结论:沉积物平面分布与水动力的时空变化存在很好的相关性;口门外发育落潮流三角洲,形成潮流沙脊、潮流冲刷槽、浅滩、拦门沙等水下动力地貌;乳山湾河流来沙已不是湾内泥沙主要来源导致沉积水动力平衡发生改变,宏观上表现在泥沙受水动力驱动发生不断运移;悬沙运移方向与涨潮流方向基本一致,湾内涨潮流带来的悬移质泥沙向湾顶运移,湾外悬移质泥沙主要向口门方向运移;湾口两侧岸段沿岸输沙方向均指向口门方向,由于乳山湾外海岸线曲折,两侧岸段以基岩为主,加之部分泥沙进入湾内,实际净输沙量小于计算值;数值模拟发现潮流单独作用与波流共同作用下泥沙蚀淤模拟差别较大;从沉积物组成、泥沙来源及滩槽稳定性三个方面分析,文章认为研究区存在航道淤积的可能性,但过程相对较慢。

As the nature of COA is very similar to a consecutive single trip charterparty, reference is made to the provisions concerning such a charterparty or volume contract in English and American laws in the analysis of the relevant legal issues relating to COA. It also studies the latest provisions regarding "volume contract" in the UNCITRAL Draft Transport Law, especially those therein reflecting the freedom of contract and those mandatorily applicable to "volume contract" as well as the proposal submitted by Australia and France.
因包运合同性质在某种程度上与连续航次租船相似,所以在分析过程中,笔者借鉴了英美国家关于航次租船合同和包运合同的相关规定,同时分析了联合国国际贸易法委员会制定的《UNCITRAL货物运输法草案》内关于包运合同(该草案将包运合同称为&volume contract&,&总量合同&或&批量合同&)的相关规定所引发的相关思考以及澳大利亚、法国关于包运合同下合同自由问题的相关提案,来进一步讨论包运合同的相关法律问题。

Lithologies are mostly sand and carbonate rocks, caps are mud rock, shale and magmatite. Entrap types are anticline, fault block rebuilt by breaking and the screened entrap diapered rock mass. The composition is CO_2, N_2, CH_4, C_2H_6 and He etc. It is magma air source body and its geologic fashions are intrusion and buried volcanic conduit. The relations between gas reservoirs and gas source bodies have three types: magma intrusion-breaking-communicated gas reservoir, magma intrusion-contacted CO_2 reservoir and buried volcanic conduit-contacted gas reservoir. The CO_2 migration in magma intrusion is consisted of fusing and crystallizing phases;it in volcanic conduit is consisted of near-surface effusion and crystallizing phases.The buoyancy of CO_2 in water far more than migration resistance in breaking or chink, CO_2 is easy float upward, the floating can results in differentiation of different density gases and concentration of sealed gas. The gas in sand reservoir firstly migrate into the higher porosity and coefficient of permeability sand, and along with the pressure going up it migrate into the lower. In magma intrusion-breaking-reservoir migration, CO_2 firstly migrate into watered breaking, began gravity differentiation and concentrate, the gas pressure time and again go up, CO_2 migrate into reservoir and concentrate under expansibility as the pressure reach upward a given extend. The CO_2 in reservoir experience four breaking modes: chemistry deposition, dissolution, diffusion and mechanic breaking, the pressure balance can be broken by faulting and the CO_2 will further migrate and form new reservoir.
济阳坳陷已发现的八里泊、阳25、平方王、平南、高青、花17 CO_2气藏主要储集层位有奥陶系、中生界、沙四段、沙三段、沙一段、馆陶组和明化镇组,储集层岩性以砂岩和碳酸盐岩为主,盖层以泥质岩、页岩和岩浆岩为主。;圈闭类型主要为受断裂改造的背斜、断块及刺穿岩体遮挡圈闭。;气体成分主要有CO_2、N_2、CH_4、C_2H_6、He等。;主要气源体为岩浆气源体,气源体的主要地质形式为侵入体和埋藏的火山通道。;气藏和气源体的空间关系有岩浆侵入体一断裂一气藏沟通型、岩浆侵入体-CO_2气储集层接触型和埋藏火山通道-气储集层接触型三种类型。;岩浆侵入体CO_2气运移分为熔融运移阶段和结晶运移阶段,火山通道中CO_2气运移分成近地表喷发阶段和结晶运移阶段。;断裂中,CO_2在水中的浮力远大于运移阻力,CO_2气容易上浮,CO_2在断裂中的易浮性导致不同密度气体的分异和走向上封闭的断裂气体相对富集。;气体在砂岩储集层运移聚集具有选择性,会优先进入孔隙度和渗透率较高的砂岩,随着压力增加,才会进入孔隙度和渗透率较低的砂岩;在岩浆气源体-断裂-储集层空间输导格架下,CO_2气在膨胀力的驱动下,首先进入含水的断裂并重力分异而聚集,气体压力会不断增高,当压力增至一定程度,CO_2气会向高孔隙度、渗透率的储集层运移并聚集。;在岩浆气源体-储集层接触空间输导格架下,CO_2气受膨胀力的驱动直接向储集层运移并聚集。;成藏的CO_2气会经历化学沉淀、溶解、扩散和机械破坏四种破坏方式,会受断裂切割而打破压力平衡,沿断裂进一步运移和聚集成藏。

The difference of bulk density of coastal soils took an effect on infiltration rate and diffuse rate. The infiltration rate and diffuse rate of coastal soils which bulk density was small were big. The water transmitting experiment of coastal soils showed that the saturated conductivity of different layers in soil profile were great, and the saturated conductivity of undisturbed soil was highly higher than that of disturbed soil. The saturated conductivity of coastal soils embanked earlier was lower than that of coastal soils embanked later. Under different water content, the unsaturated conductivity of coastal soils had a great change and the bulk density had an effect on unsaturated conductivity. The soil with a low bulk density had a high unsaturated conductivity. Chlorine ion moved in coastal soil was an inert ion. The distribution of CU in soil was definite and repeated, which is no relation with the time and velocity of infiltration. The concentration of infiltration solution and the texture of coastal soils had no apparent effect on solute movement synthetic dispersion coefficient, while bulk density took an apparent effect on solute movement synthetic dispersion coefficient. Synthetic dispersion coefficient of coastal soils increased as bulk density decreased.

Settlement characteristics are studied based on formula of suspended sediment settling velocity and previous research results. Results show that the suspended sediment flux quickly decreases from the Hangzhou Bay to the offshore area. Although the suspended sediments are primarily transported towards the offshore area, net transport towards the Hangzhou Bay is also found in the study area. The study area is basically located in hydrodynamic balance belt, and the suspended sediment transport is characteristics of reciprocating movement and small amount of net sediment discharge. The net suspended sediment transport is mainly controlled by average current transport, Stokes drift-induced transport and gravitational circulation transport. The advection transport effect gradually weakens and gravitational circulation transport evidently intensifies from Hangzhou Bay to the offshore area. Settling velocity of single particles is far smaller than that of floccules, so, influence of flocculation of suspended sediments must be taken into the consideration.
结果表明,研究区净悬沙通量自杭州湾内向外海迅速变小,悬沙总体由杭州湾向外海输运,但同时存在向杭州湾方向的净输沙;研究区基本处于水动力平衡带,悬沙输运具有往复搬运、净输沙量小的特点;平均流输运、Stokes漂移输运和垂向净环流输运是引起悬沙泥沙净输运的主要作用机制,自口门至外海,平流输运作用逐渐减弱,垂向净环流输沙在悬沙净输运中所占比例逐渐增加;舟山群岛海域既是杭州湾向东海输运泥沙的重要通道,也是东海沿岸流携带泥沙向南输运的过渡地带;研究区单颗粒泥沙沉降速度很小,远小于絮凝沉降速度,在研究本区悬沙沉降时必须考虑絮凝的影响。
