This research attempts to provide theory solutions to qualitative estimation and scope the water exchange and contaminant transport between stream and groundwater.

Numerical Simulation for Water and Non-conservative Contaminant Transport in Soils

水分及非保守性污染物在土壤中运移数值模拟

Models of water and contaminant transport in a compacted clay liner ( CCL), a geomembrane liner and a composite liner were developed to compare the abilities of the three liners to prevent leachates and contaminants from migrating out of the landfills.

为改进填埋场防渗层系统结构设计，建立了压实粘土衬层、土工膜衬层和复合衬层这三种衬层中水分与污染物迁移的数学模型。

Furthermore, industrial construction adjustment, technique improvement and water contaminant treatment should be taken for the protection of water environment and sustainable development of the region.

此外，为保护水环境和实施区域的可持续发展，必须大力调整产业结构，提高产业的技术水平和加大对水环境的治理力度。

Both the physical and biological containment systems are divided into different levels.

物理和生物遏制分为不同的水平。

In general, the stricter the physical containment, the less strict is the biological containment. On flexible protection and stiff protection for structure safety under explosive/ impact loading

总之物理防护措施越严，生物防护措施则可稍松。强动载荷下结构的柔性防护和刚性防护

The momentum integral method is applied in the frame of safety analysis of pressure water reactors under hypothetical loss of coolant accident ( LOCA) conditions to simulate numerically film condensation, rewetting and vaporization on the inner surface of a pressure water reactor containment.

采用动量积分方法分析压水堆发生失水事故时在安全壳的内表面上的液膜凝结、再浸润和蒸发过程。

And it will include closing off the valves on that new containment cap so that they can take solid readings of the pressure inside of that containment cap and inside that well.

包括关闭新的控油罩上的阀门，这样他们就可以读取控油罩和油井内部压力的稳定数据。

Solution 3_C indicates the 10 PARs have successfully recombined 667 kg of hydrogen within 24 hrs. As a result, maximum hydrogen concentration is as low as 3.12%, pressure inside the containment accumulates to about 0.4 MPa.

方案3C表明10台氢气复合器在24h内有效地复合了667kg氢气，安全壳大空间最大氢气摩尔浓度为3.12%，安全壳内压力约为0.4MPa。

The result showed that the hydrogen combustion can be avoided or mitigated substantially by shorter spray duration and proper start time to activate the spray, and thus the time for the pressure in the containment reaching the limit can be retarded.

结果显示，采用较短的喷淋持续时间和适宜的喷淋投入时间，能较明显地避免氢燃或降低氢燃的强度，从而延迟安全壳内压力到达限值的时间。

This paper introduces the selection of the CIP containment system, the design of containment, the determination of the design pressure for the containment and the calculation analysis of the containment structure.

本文介绍了CIP安全壳系统方案选择、安全壳设计、安全壳设计压力的确定以及安全壳结构的计算分析。
