The beach body of Lower Triassic Feixianguan Formation in northwestern Sichuan can be divided into platform marginal oolitic beach and intraplatform point beach. The water is relatively deeper at the forming of most of platform marginal oolitic beach which is not transformed by the diagenesis of fresh water and mixed water and has poor reservoir properties. However, a part of oolitic beach formed under shallow water environment, and it is transformed by the diagenesis of fresh water and mixed water and well dolomitized, which can form excellent reservoir.

川西北下三叠统飞仙关组滩体分为台地边缘鲕粒滩和台地内点滩2种类型，多数台地边缘鲕粒滩形成时水体相对较深，未经大气淡水和混合水的成岩改造，储集性能较差，局部鲕粒滩形成时水体较浅，在经过大气淡水和混合水的成岩作用改造后，白云石化好，可形成储集性能极好的储集体；台地内点滩白云石化较好，储集性能也较好，但分布狭窄，厚度较薄，无规律可寻。

The results indicate that when formation water in Guantao formation is used as a source of water injection in the oilfield,the compatibilities of injected water with reservoir water and injected water with crude oil are better and the injected water with reservoir stone is poor.

结果表明，该油田以馆陶组地层水作为注入水水源时，注入水与油层水的相容性较好，与地层原油的配伍性较好，与岩石的配伍性不好。

First of all,we tested the germination and water uptake rate of 47 species typical xerophil seeds grow up in north China from 20 families,38 genuses under sufficient water and different Grads water stress by high-molecular-weight polyethylene glycol(PEG6000).The results show that Xerophil seeds from the same habitat exhibited similar patterns in response to water stress.Xerophil seeds from arid community were stronger in germination and imbibition than that from other two communities under serious water stress,whereas Xerophil seeds from humid community were sensitive to any degree of water stress.Namely,the seeds live in arid habitat possessed high germination and quickly water uptake in sufficient water or any degree of water stress,but the others grow up in humid habitat shown significant difference which germination and water uptake well under sufficient water but inhibited even if slight water stress.

首先，我们通过对20个科，38属，47种旱生植物种子在水分充足和不同梯度的干旱处理(聚乙二醇PEG6000)条件下的萌发率及吸水率实验发现，当水分胁迫强烈时，分布于干旱沙漠地区的植物种子其吸水率和萌发率都高于半干旱和湿润地区的植物群落，相反，湿润地区植物种子的吸水率和萌发率对任何的水分胁迫都表现出敏感的响应趋势，也就是说，生境恶劣的植物种子在较强的干旱胁迫下，仍然保持了较高较快的萌发率及吸水率，水分充足与水分缺乏时无显著差异，而生境相对较好的植物种子在水分充足情况下萌发与吸水良好，但在干旱胁迫时则受到明显抑制，水分充足与水分缺乏时差异显著。

It is not essential to build a storage or impounding reservoir if the water can be stored in the ground.

如果能将水储存在地下，就没有必要建造水库或蓄水池。

Periodic impounding and draining of the water reservoir would be implemented after the projects were in service.

Ahead impounding water of Three Gorges reservoir is an important problem of getting more benefit of Three Gorges Project, but it will inevitablely increase the risk of flood control. It is necessary to put forward an effective scheme to meet the flood control requirement.

三峡水库提前蓄水是充分发挥三峡水库效益的重要课题，而提前蓄水必然会提高三峡大坝的防洪风险，有必要提出一个有效的调度力案解决。

Under the current (1996) conditions of planned irrigative and municipal water supply of Shihmen Reservoir, inflow discharge at the damsite, estimated flows at downstream control points and other associated data, the annual shortage ratio and shortage index through reservoir operation simulation are called the basic shortage ratio and shortage index. These two numbers are the criteria to evaluate the reliability of water supply from the Reservoir.

摘要探讨石门水库在现况(民国85年)灌溉及公共给水计画配水情况下，以石门坝址之流量纪录及其下游控制点之推估流量，配合水库相关资料，经由所建立之水库运转程式，模拟其年平均缺水率及缺水指数，此称之为基准缺水率及缺水指数，以作为水库供水可靠度之比较标准。

Aiming at the currently shortage of XML streams quality detecting, this paper proposes a new forecasting method of XML streams quality by least squares support vector machines, which is used the method of XML keys' vector matrix as windows, and vector product wavelet transform to multilevel decompose and refactor the XML streams series, that can fulfill real-time checking demand of XML quality, and ensure constraint, consist- ency and integrality. For even more adapting net load, it proposes a control strategy by weight and adaptive adjustment to ensure XML streams quality.
