不平均的

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。

Finance Minister Bill English said workers on the average wage would be hit with the top 38c tax rate if tax rates remained the same.

财政部长Bill English说，如果税率结构保持不变，当平均工资达到上述平均值的话，所需支付的税率将达到现有税率区间的最大值——38%。

In summery, this study has proved that biotype in BPH is a very complex phenomenon, and the quantitative resistance does really exist in rice varieties.

但是因为在过去 32 年间，大多数人的体重是增加而不是减少，其结果是，平均而言，人们的体重是在增加。

As I mentioned earlier, the yearend prices of our major investees were much higher relative to their intrinsic values than theretofore. While those prices may not yet cause nosebleeds, they are clearly vulnerable to a general market decline. A drop in their prices would not disturb us at all - it might in fact work to our eventual benefit - but it would cause at least a one-year reduction in Berkshire's net worth. We think such a reduction is almost certain in at least one of the next three years.

就像是我上次所提到的，相较于过去，我们这些被投资公司的股价已高于其实质价值，虽然目前以这种价位不会造成我们流鼻血，但难免会受到大盘波动的影响，当然股价下挫一点都不会造成我们的困扰，甚至反而对我们有利，但不可避免地可能会造成伯克希尔年度净值的减少，只要在未来的两，三年间，我们的投资组合市值平均每年减少 10%，就有可能会发生这种状况。

The results of The biological characteristics of Semanotus bifasciatus have showed: 1. The hole of Semanotus bifasciatus associated with a certain temperature.2.The main damages of Semanotus bifasciatus located oriental arborvitae tree trunks, while above 3m parts are not damaged. 3.The Mating numbers of Semanotus bifasciatus are not unique ,and the duration varied due to the different individuals, the average duration is 3.2 minutes . 4. when are flying , they are more sensitive to blue and green; while moved, they are more sensitive to black.

对双条杉天牛的生物学特性的研究结果表明：双条杉天牛出孔与温度有一定的相关性，温度过低，双条杉天牛停止出孔；对于树高7m以上的树，主要危害侧柏基部的1-3m的主干部分，3m以上基本不受害；双条杉天牛需要经过一段时间的抱合才能交尾，交配对象不专一，雌雄成虫均可以多次交尾，交尾时间长短不一，平均3.2min/次；飞行时对蓝色和绿色较为敏感，爬行时对黑色较为敏感。

The decreased threshold shear velocity and unsaturated sand flows at the stoss slope of the dunes resulted the erosion at the toe of the dune. Under the medium and low drifting-sand winds the sands being transported have divergence with that on the surface, the mean grain size of transported sands is lower than that on the surface and the sand transporting is a stochastic process.

起动剪切速度减小与不饱和风沙流是沙物质在横向沙丘迎风坡坡脚不能产生沉积的主要原因；再者，平均风速并不能完全反映野外实际状态下气流的性质，在低－中强度的风沙活动过程中，被输送的沙物质的粒度组成与下垫面物质有明显的差异。

The results showed that the sex ratio of trees was 1 m 2 f, and the natural T. cuspidata tree was able to sexually reproduce for many years. Male trees had fecundity when the diameter at breast height ranged from 1.5 cm to 92 cm, while female trees had fecundity when the DBH from 9.5 cm to 68.1 cm. Male trees typically flowered at the age about 20 years earlier than female trees. The numbers of microstrobili were 3 times more than that of megastrobili, and only 1/10 megastrobili developed into seed. The numbers of strobili and seed were correlated with DBH, crown diameter and height of trees; however, no significant correlations were observed with other site factors. Numbers of strobili decreased from the upper to lower canopy layers, while the quantity of seed decreased from the middle, upper to lower canopy layers. Seed-setting rate increased from the upper to lower canopy layers. Numbers of strobili and seeds in different directions of the canopy were not uniform, but the differences weren't significant.

For the other three Bell states, there will appear the periodical collapse revival of atomic populationif the initial mean photon number reaches some special values. With the increase of the initial mean photon number, the oscillation frequency of the time-evolution of atomic population increases correspondingly, and the amplitude decreases.
