The main factors affecting the soil-structure interface behaviors were found experimentally and theoretically, including: 1 the thickness of the interface that is five to six times the average grain size of the soil; 2 the aeolotropy of interface, which is responsible for anisotropic response of the stress-strain response of the interface; 3 two physical states, including crashing and compression of the soil near the structure surface, which govern the stress-strain response of the interface strongly; 4 two shear deformation components due to sliding and constraint of the structure surface relative to the soil respectively, which forms the deformation of the interface; 5 the volumetric strain due to dilatancy, which is found to be composed of a reversible dilatancy component and an irreversible dilatancy component. 4. A unified constitutive model of the interface, based on new elasto-plasticity damage theory, was developed. It was confirmed to be effective for the conditions considering monotonic and cyclic shearing, coupling effect of shear and volumetric strains, evolution of physical state, micro-structure aeolotropy of the soil and the resulting aeolotropy of the interface as well as the three normal boundary conditions stated above. 5. 2D and 3D finite element formulations of the present model were derived and incorporated into the FEM codes. They were applied to the evaluation of practical engineering problems with different typical interfaces between soil and structure. The new model was shown to be reasonable and effective.

确定了粗粒土与结构接触面厚度约为5～6倍的平均粒径，首次揭示了接触面的细观结构异向性以及由此所引起的宏观剪切异向性，发现了在单调和往返剪切荷载作用下土颗粒破碎和剪切压密两种物态变化机制共同支配着接触面力学性质的变化，通过细观分析证实了接触面的变形可分解为一般同时发生的土与结构交界面上的滑移变形以及结构面位移约束范围之内土体本身的剪切变形两部分，观测到接触面受剪时表现出明显的相对法向位移，并可分解为可逆性和不可逆性两个分量；(4)建立了第一个能够统一地描述单调与往返剪切特性、剪应变与体应变耦合特性、细观结构和宏观剪切异向性以及土颗粒破碎等物态变化特性的土与结构接触面弹塑性损伤本构数学模型，并采用多种法向边界条件复杂加载路径的试验成果验证了新模型的合理性和有效性；(5)提出了新模型的二、三维有限元格式并结合实际边值问题进行了应用计算分析，比较了不同接触面本构模型对计算结果的影响，证实了新模型及其有限元格式不仅能够合理地描述土与结构接触面的主要力学特性，还能够较好地反映土体与结构物在接触面处的滑移、脱开等不连续现象。

When is a frequently used polysemous temporal connector denoting not only temporal relations of anteriority, simultaneity and posteriority, but also the extended concepts of contrast, conditionality, cause-result and adversativeness.

提 要：时间连词when是英语中使用频率高、多义的连词之一。它连接的主从句既可以表达相继或同时发生的时间关系，也经常用来指称对比、条件、原因、让步等抽象概念。

It was also found that no obvious boundary existed between spinodal decomposition and cellular decomposition, the wavelength of spinodal decomposition was 2.16nm.

同时还发现，调幅分解几乎与胞状分解同时发生，二者之间没有明显界限，调幅波长为2.16nm。

If multiple players would make choices and/or take actions at the same time, the active player makes any choices required, then the next player in turn order (usually the player seated to the active player's left) makes any choices required, followed by the remaining nonactive players in turn order. Then the actions happen simultaneously.

若多位玩家需要同时做决定和／或采取动作，则先由主动玩家作决定，再由非主动玩家作决定；之后这些动作同时发生。

There are three fundamental stratagems:(1) construct new economical ecol-ogy structure----to disconnect input of environment resources and economy de-velopment;(2) establish precautious landscape policies----there are three relatedand coinstantaneous processes: aggravation of landscape damage, knowledgeacquiring and public awareness.

同时，本文建设性地提出了景观恢复的3个基本方略：(1)确立新的经济的生态结构——使环境景观的投入与经济增长脱钩，通过4大投入要素与GDP关系的举例，分析讨论了生态结构与经济结构改变的趋势；(2)制定预防性景观、环境政策——通过损害环境、景观的代价举例分析，讨论了环境政策制定有三个相互关联而且同时发生的过程：环境景观损害日益加重、加剧；人类获取技术知识；公众觉悟。

Most of the recent domestic researches with the Balanced Scorecard approach were more concern with its merit and benefit than its application, which faced difficulty. With this understanding, this article chose a local dominant manufacturer in decoration materials as a study case to review its application of balance idea from the four prospective, which are financial prospective, customer prospective, business process prospective, and learning and growth prospective, of Kaplan and Norton.

中文摘要考量国内目前相关绩效衡量指标之文献与研究，多以探讨企业导入平衡计分卡的优点及效益为主，对於企业於推行及应用时，所面临的困难及问题探讨并不多，同时由於产业的属性及经营方式多有不同，所以更可能同时发生技术面、人为面、组织面的问题亦未深入处理。
