一般都是根据期刊的审查标准，所以如果是期刊审查过的就不是original article。如果是一般论文修改机构像是wordvice, editage这种改过的文章，也不会称作是reviewed article。另外给修改机构改完后可以申请一个叫做润色证明(editing certificate)，这通常是期刊要求作者去给机构修改后作为证明用的。提供参考。

Oracle DBA神器：PRM-DUL灾难恢复工具可以直接从这种受损的Oracle数据库中将数据拯救出来。当你的数据库因为ORA-00600/ORA-07445或其他ORA-报错，或丢失关键的system表空间数据文件，或ASM diskgroup损坏时均可以考虑采用PRM-DUL来做恢复。PRM-DUL采用独创的DataBridge恢复技术，直接从数据文件中抽取数据后可以像DBLINK那样直接插入到新建数据库中，而无需数据落地成为DMP文件占用空间。

在ORACLE中ONDELETECASCADE和ONDELETESETNULL两个命令主要在外键改foreignkey约束中使用，主要区别体现在对数据的影响上。其中ONDELETECASCADE的功能是在主数据删除的时候，从属数据一并删除,常用于强耦合关系中。而ONDELETESETNULL的功能是在主数据删除的时候，从属数据不会删除，只是将从属数据的关联属性字段设置成NULL，从而变为无主待关联数据，这个常用于弱耦合关系中。主键和外键是两种类型的约束，可用于强制表中的数据完整性。这些是重要的数据库对象。外键(FK)是用于在两个表中的数据之间建立和加强链接的一列或多列的组合，可控制可在外键表中存储的数据。在外键引用中，当包含一个表的主键值的一个或多个列被另一个表中的一个或多个列引用时，就在这两个表之间创建了链接。这个列就成为第二个表的外键。详细内容请参考《Oracle外键约束_百度文库》

楼主您好drop user ； 仅仅是删除用户，drop user ×× cascade ；会删除此用户名下的所有表和视图。userSpecify the user to be dropped. Oracle Database does not drop users whose schemas contain objects unless you specify CASCADE or unless you first explicitly drop the user"s objects.CASCADE Specify CASCADE to drop all objects in the user"s schema before dropping the user. You must specify this clause to drop a user whose schema contains any objects. 使用cascade参数可以删除该用户的全部objects。要说明的如下：1 If the user"s schema contains tables, then Oracle Database drops the tables and automatically drops any referential integrity constraints on tables in other schemas that refer to primary and unique keys on these tables. 如果用户的schema中有表，则在删除表的时候自动删除与该表相关的主键和外键。2 If this clause results in tables being dropped, then the database also drops all domain indexes created on columns of those tables and invokes appropriate drop routines. 如果用户的schema中有表，则在删除表的时候自动删除与该表相关的索引。3 Oracle Database invalidates, but does not drop, the following objects in other schemas:删除用户时，下列在其他用户中的objects不会被删除，只会被置为无效1 Views or synonyms for objects in the dropped user"s schema视图，同义词2 Stored procedures, functions, or packages that query objects in the dropped user"s schema存储过程，函数，包4 Oracle Database does not drop materialized views in other schemas that are based on tables in the dropped user"s schema.

The geochemical or long-term carbon cycle primarily involves the exchange of carbon between the ‘surficial"and ‘geologic"reservoirs. The former comprise atmosphere，oceans，biosphere， soils，and exchangeable sediments in the marine environment ( Fig. 1) while the latter include crustal rocks and deeply buried sediments in addition to the underlying mantle. How carbon is partitioned between the various reservoirs of the surficial system and between surficial and geologic reservoirs is what sets the concentration of CO2in the atmosphere. Life，and the cycle of organic carbon，as well as its geological ( and subsequent fossil fuel exhumation ) is of particular importance in this regard. The cycle of carbon in its inorganic，calcium carbonate ( CaCO3) form also affects atmospheric CO2，but by more subtle means. It also plays a fundamental role in regulating ocean chemistry and pH—a major factor in the viability of calcareous marine organisms.Carbonate precipitation and burialToday，the surface of the ocean is everywhere more than saturated ( over-saturated) with respect to the solid carbonate phase，with a mean value for the saturation state ( Ω: saturation state of the solution，also known as the solubility ratio) of calcite of 4. 8. In other words，the minimum thermodynamical requirement for calcite to precipitate is exceeded by a factor of almost 5. Despite this，the spontaneous precipitation of CaCO3from the water column is not observed in the ocean. This is because the initial step of crystal nucleation is kinetically unfavorable，and experimentally，spontaneous ( homogeneous) nucleation does not occur in sea water solutions until Ωcalcite＞ ～ 20 – 25 ( Ω = ［Ca2+］×［CO2-3］ /Ksp) . Although CaCO3precipitation occurs as cements and coatings in the marine environment，it is primarily associated with the activities of living organisms， particularly corals， benthic shelly animals， plankton species such as coccolithophores and foraminifera，and pteropods，and where it takes place under direct metabolic control. In comparison，carbonate deposition in fresh-water systems is of only minor importance globally，and will not be discussed further here.While not in itself sufficient to drive substantial abiotic precipitation，the saturation state of the modern ocean surface is favorable to the preservation of carbonates deposited in shallow water ( neritic) environments. Long-term accumulation of this material can result in the formation of extensive marine topographical features such as barrier reefs and carbonate banks and platforms. A different fate awaits CaCO3precipitated in the open ocean by plankton such as coccolithophores and foraminifera，however. This is because oceanic waters become increasingly less saturated with depth. Below the depth of the saturation horizon，conditions become under-saturated ( Ω ＜ 1. 0) and carbonate will start to dissolve. In the modern ocean the calcite saturation horizon lies at about 4500 m in the Atlantic and ～ 3000 m in the Pacific Ocean. Within a further 1000 m sediments are often completely devoid of carbonate particles ( the carbonate compensation depth， or CCD) . Topographic highs on the ocean floor such as the mid-Atlantic ridge can thus be picked out by sediments rich in CaCO3while the adjacent deep basins are low in % CaCO3. The visual effect has been likened to snow-capped mountains. The pressure induced surface-to-deep vertical contrast in Ω is further enhanced by the respiration of organic matter and release of metabolic CO2 in the ocean interior which suppresses the ambient carbonate ion concentration and thus Ω. The greater accumulation of metabolic CO2in the older water masses of the deep Pacific explains why the sea-floor there is much poorer in % CaCO3compared to the Atlantic at a similar depth.Fig. 1 The global biogeochemical cycling of calcium carbonate. ( a) Modes of CaCO3transformation and recycling within the surficial system and loss to the geological reservoir ( labeled ‘1 " through ‘4 ") .① Precipitation of calcite by coccolithophores and foraminifera in the open ocean; Ca+2+ 2HCO－3→CaCO3+CO2( aq)+ H2O. ② Carbonate reaching deep-sea sediments will dissolve during early diagenesis if the bottom water is under-saturated and / or the organic matter flux to the sediments is sufficiently high. ③ Precipitation of CaCO3by corals and shelly animals，with a significant fraction as the aragonite polymorph. Because modern surface waters are over-saturated relatively little of this carbonate dissolves in situ，and instead contributes to the formation of reefal structures or is exported to the adjoining continental slopes. ④ Precipitation of CaCO3 results in higher pCO2at the surface，driving a net transfer of CO2from the ocean to the atmosphere.( b) Modes of CaCO3transformation and recycling within the geologic reservoirs and return to the surficial system ( labeled“5”through“8”) . ⑤ CaCO3laid down in shallow seas as platform and reef carbonates and chalks can be uplifted and exposed to erosion through rifting and mountain-building episodes. CaCO3can then be directly recycled; CO2+ H2O + CaCO3→Ca+2+ 2HCO－3. ⑥ Thermal breakdown of carbonates subducted into the mantle or deeply buried. The decarbonation reaction involved is essentially the reverse of silicate weathering，and results in the creation of calcium silicates and release of CO2; CaCO3+ SiO2→CO2+ CaSiO3.⑦ Weathering of silicate rocks; 2CO2+ H2O + CaSiO3→Ca+2+ 2HCO－3+ SiO2. ⑧ Emission to the atmosphere of CO2produced through decarbonation. This closes the carbon cycle on the very longest time-scales.Unfortunately，the carbonate cycle does not conform to this simple picture，and a significant fraction of CaCO3appears to dissolve in the water column even before it can reach the sediment surface. This has been something of an enigma because the reduction in carbonate flux measured by sediment traps occurs well above the depth at which calcite becomes thermodynamically unstable. Dissolution of carbonate particles in acidic digestive conditions of zooplankton guts has been one proposed mechanism. Acidic micro-environments within individual ‘marine snow " aggregates may also be important. Another possible explanation surrounds the aragonite polymorph because it becomes susceptible to dissolution at much shallower depths than calcite under the same ambient conditions. In support of this are recent estimates of the depth at which most CaCO3 dissolution occurs in the ocean which appears to correspond to the aragonite saturation horizon. However，calculations suggest that solute release from sinking pteropod shells，the main aragonite product in the open ocean，should mostly occur much deeper than this. Dissolution of aragonite also does not help explain how 65% of calcitic foraminiferal tests can be lost at shallow depths. This uncertainty is of concern because a full appreciation of the controls of atmospheric CO2and response to global change requires an understanding of the dissolution and the depth of recycling of CaCO3in the water column.Overall，more than 80 % of all carbonate precipitated in the open ocean dissolves either in the water column or within the uppermost layers of the underlying sediments. The remainder，some 1 Gt CaCO3yr－ 1accumulates in deep-sea sediments. This burial loss，to which can be added as much as another 1 Gt CaCO3yr－ 1of deposition in neritic environments ( although the uncertainty in this figure is substantial) ，must somehow be balanced if the ocean is not to run out of calcium ions! This is achieved through the weathering of carbonate and silicate rocks.Weathering and Carbonate RecyclingThe weathering of calcium carbonate and calcium silicate minerals in soils and at exposed rock surfaces helps balance the CaCO3sedimentation loss by unlocking Ca2 +from the geologic reservoir. Alteration of ocean crust by percolating fluids adds an additional but more minor contribution. The weathering reactions ( see Fig. 1b; ⑤ and ⑦) provide the other raw material necessary for carbonate precipitation— bicarbonate ions ( HCO－3) . However，because the transformation 2CO2→2HCO－3( Fig. 1b; ⑦) is internal to the surficial system and does not represent a source of new carbon，the component of CaCO3burial derived from silicate rock weathering represents a loss of carbon to the geologic reservoir. This must be replaced on the long-term，achieved through the release of CO2to the atmosphere from volcanic sources. ( In contrast，the weathering and burial of CaCO3results into net loss or gain of CO2to the surficial system) .A powerful regulatory mechanism of the Earth system arises because weathering rates respond to surface temperature and atmospheric CO2while simultaneously silicate weathering rates control the rate of transformation CO2→HCO－3and thus rate of loss of carbon through CaCO3burial. This is a negative feedback system and acts to regulate the concentration of CO2in the atmosphere over hundreds of thousands of years.Buried carbonate is eventually recycled back from the geologic reservoir. This can occur if carbonates laid down in shallow seas such as limestones or chalks are subsequently uplifted and exposed to weathering as a result of mountain building episodes. However，carbonates deposited in open ocean sediments are only infrequently exposed at the Earth"s surface，as ophiolite complexes—portions of the oceanic crust and overlying sediments that have been trapped between colliding cratonic blocks and uplifted. Instead，the primary recycling of deep-sea CaCO3occurs through subduction into the upper mantle and decarbonation ( Fig. 1b; ⑥) .At this point it is important to recognize that carbonate burial represents the principal geologic mechanism of CO2removal from the ocean and atmosphere. However，the act of precipitating CaCO3has the effect of re-partitioning dissolved carbon in the surface ocean into CO2 ( aq)，raising ambient pCO2and pH. Thus，precipitation and deposition of CaCO3have the short-term effect of increasing the concentration of CO2in the atmosphere at the expense of the ocean carbon inventory，but at the same time represents the ultimate long-term sink for CO2.Both texts are selected from: The role of the global carbonate cycle in the regulation and evolution of the Earth system，Earth and Planetary Science Letters 234，2005: 299 － 315By: Andy Ridgwell，Department of Earth and Ocean Sciences，The University of British Columbia，6339 Stores Road，Vancouver，British Columbia，Canada V6T 1Z4andRichard E.

B 句意：洪灾过后，那个地区的人们正在受苦。为了生存，他们急需干净的水、药品和住所。将先行词people代入定语从句后为：people urgently needed clean water，medicine and shelter to survive，可知先行词在从句中作主语，所以排除C项；what不能引导定语从句，故排除D项；因为先行词为“人”，所以排除A项。故答案为B项。
