The thicker the DBL is, the stronger the inhibition will be. Thus, the presence of DBL in a polder reservoir can result in a delay of natural clearing process of polluted water. The effect of salt release from deposited sediments on the water quality will be a long lasting process.

另外，由于扩散边界层的存在，限制了水动力对沉积物与上覆水之间物质交换的增强作用，所以海湾水库沉积物中蓄积盐分对上覆水的影响将是长期的过程。

The results showed that:(1) low N stress significantly decreased the leaf SPAD value, leaf nitrogen content, nitrate reductase activity and reduced distance between leaf-umbrella, leaf area. And these impact aggrandized as the stress intensity increased.(2) Responses to low-N stress were in different degrees between different varieties of rubber tree seedlings. On the whole, GT1 was most sensitive to stress, PR107 next, and RRIM600 was the least sensitive.(3) The SPAD value, DBL, LA were significantly positive correlated with LNC, NRA in the seedling leaves.

结果表明：（1）缺N胁迫明显降低了叶片SPAD值、叶片N含量和硝酸还原酶活性，缩小了叶蓬距、叶面积，且影响幅度随胁迫强度的加大而增大；（2）不同品种橡胶树实生苗对缺N胁迫的响应程度不同，总体上GT1较为敏感，PR107次之，RRIM600较不敏感；（3）橡胶树实生苗叶片SPAD值、叶蓬距、叶面积与叶片N含量、硝酸还原酶活性之间均呈显著或极显著正相关。

Based on present researches,by means of modern measurement and analysis techniques,systemic laboratory experiments,field investigations and through theory researches were conducted.And following are the major points and achievements presented in this dissertation:①The micro-convexity on fracture plane was studied.Analyzing and comparing the static attribute and dynamic variation of natural fracture with the artificial,untreated fracture,artificial and scabbled fracture as well,making out the criteria that artificial and scabbled fracture simulate natural fracture.②We take the effect of all the three primary stresses and stress invariant into account in the Lade-dbl yield criterion,which can preferably reflect all the yield and destruction characteristic of the rock material.

结合裂缝性储层应力敏感性研究现状，利用现代化测试手段，通过系列的室内实验以及深入的理论探讨，本文取得的研究成果包括以下几个方面：①从裂缝面上的微凸体入手，分析和对比了天然裂缝、人工但未经过处理的裂缝，以及经过粗化处理以后的人工裂缝的静态特征和动态变化，指出了经过粗化处理以后的人工裂缝模拟天然裂缝的依据；②Lade双曲服面屈服准则考虑了所有三个主应力或应力不变量对屈服与破坏的影响，能够较好的反应岩石材料的所有屈服和破坏特性。

Firstly, based on foreign engineering experience and result of research, combining with test trial road, soil condition is the most important factor to rubllization, elsewhere DBL has little influence.

The exchange of substances between deposited sediments and overlying water must also pass through the DBL. In this study, two series of flume experiments with and without wind blowing conditions were conducted to study the salt release process from sandy sediments in a polder reservoir. The thickness of DBL was directly measured. The experimental salt fluxes through the DBL under the two wind conditions were inter-compared and compared with the estimations using the Fick's first law in an effort to explore the role of DBL in contact inhibition of salt release.

通过无风和有风条件下两组沉积物盐分释放实验，研究海湾水库砂质沉积物－水界面扩散边界层的形成情况，并通过水动力扰动下穿过扩散边界层的实测盐分通量与Fick第一定律理论计算通量的比较，以及扰动与无扰动时通量的比较，探讨扩散边界层对沉积物盐分释放的影响。

Results indicate that the observed salt fluxes under the two wind conditions show a marginal difference. Under the steady wind condition, a DBL with a constant thickness of 3.5 cm is observed right above the deposited sediment. The molecular diffusion is found to be the dominant mechanism for salt transport within the DBL. The latter can suppress the hydrodynamic enhancement on the exchange of substances between deposited sediments and overlying water.

研究结果表明，在稳定风场条件下，沉积物－水界面处存在厚度约3.5cm的扩散边界层，有风条件下的界面盐分交换通量略大于无风时的通量；分子扩散是边界层内盐分运移的主要机制，扩散边界层对沉积物盐分释放具有阻滞作用，并且边界层越厚，阻滞效应越显著。
