In order to evaluate the risk of groundwater contamination resulting from pesticide leaching, a new fugacity model was developed on the basis of former researchers'work. In this model soil was divided into two compartments: unsaturated consisted of three subcompartments: air, water, and soil solid, and saturated phase consisted of two subcompartments: water and soil solid.

Educational Policy from the Perspective of Structuralism Western structure-functionalism theory,structure theory of scientific revolution, institutional transfer theory and western policy process theory have provided for us a helpful framework of analysis in understanding the generation and transfer of structure of educational policies, the complexity and richness of which give us an implication that we must understand and master it from the angle of structure and dynamic generation.

西方结构功能主义理论、科学革命结构理论、制度经济学关于制度变迁理论以及西方政策过程理论为理解教育政策的结构生成和结构变迁提供了有益的分析框架。教育政策本身的复杂丰富性启示我们必须从结构和动态生成的角度对其进行理解和把握。教育政策结构由外围层、中间层、核心层三个部分组成。

One way is to use risk metalanguage (a formal description with required elements) to provide a three-part structured "risk statement", as follows :"As a result of , may occur, which would lead to ."

有一种方法是使用风险元语言（一种包含必要元素的正式描述）提供一个由三个部分组成的"风险陈述"，即"作为确定的原因引起的结果，不确定性事件可能发生，而不确定性事件又会导致对目标产生的后果。"

本文详细介绍应用在双向拉伸薄膜生产线上的X射线测厚仪的研制和设计过程。主要从三个方面对研制和设计作了详细介绍。首先从X射线测厚仪的硬件结构进行描述，阐明各个硬件的组成和原理，并着重介绍了在设计中各个硬件的类型和功能实现。

A dye recycled photosensitization system has been designed. As a result of studies in the mechanism of electron transfer reaction of xanthene iodonium salt, it is proposed that the dye-recycled process consists of three-step reactions during the photosensitization: The oxidative fading product of dye is formed through electron transfer under irradiation; In the presence of H-donor, product changes into acidic leuco dye product; Product undergoes deprotonization under action of base to regenerate initial dye.

本文设计了染料循环再生的光敏反应体系，通过对占吨碘翁盐电子反应机制的深入研究，提出了占吨染料在光敏反应过程中的染料再生循环，它依次由三个反应过程组成：在光作用下，通过电子转移反应，产生染料氧化褪色体；在H给体存在下，通过H转移反应，使产物转化为染料酸式隐色体；在碱作用下，发生去质子反应，染料再生回复到染料的起始结构。

The three tetranuclear copper complexes are structurally analogous and they all consist of a pair of [Cu22]+ or [Cu22]+ fragments bridged by a deprotonated dicarboxylate into dumbbell-shaped, neutral, tetranuclear molecules.
