查询词典 B horizon

Results show that Cu, Zn, Pb, and Rb were relatively enriched in the buried paleo-surface horizon (2A) and paleo-argillic horizon (2Bt), where natural pedogenic eluviation and illuviation was playing a main role. Under the relatively warm and moist climate, Sr leaching was strong, showing entirely contrary distribution characteristics with obvious loss in the horizons of 2A and 2Bt.

结果表明，受介质的吸附、碳酸钙等易淋溶组分的淋溶淀积、作物吸收等因素影响，痕量元素Cu、Zn、Pb、Rb在剖面上总体呈中高型分布，即在干润淋溶土表层（2A层）和黏质化B层（2Bt层）含量有所增加而表现为富集；而Sr则发生强烈迁移，在2A层、2Bt层含量显著降低。

With an additional terminal cost in the standard finite horizon objective functional and a terminal inequality constraint,the prediction is expanding quasi to infinity but the control profile to be determined by on-line optimization is only of finite horizon.

开环优化问题含有附加的终端代价项和终端约束条件，这样预测时域延伸至准无限，而需在线优化获得的控制函数仅为有限时域。

After about 30 years, Hintikka returned to this topic and deepen the interpretation in 1996, but at this time he changed his method and horizon, the irresolvable theoretical dilemma made him hard to insist the point in 1962 (2.5-2.6). Hintikka's method and horizon were rather peculiar, his article was full of jumping inference.

2.3-2.4欣提卡也于1996年再次回到这个话题，深化1962年的诠释，不过这时，他的诠释方法和视野却发生了巨大的转变，难以解决的理论困境使其最终没有坚持1962年的诠释立场。

Hours, as the sky darkened and rain plummeted around us in a suddendeluge.bitter, slightly resinous, but still pleasant — the high, keening soundof the cicadas in July, the feathery barrenness of the trees, the verysize of the sky, extending white-blue from horizon to horizon, barelyinterrupted by the low mountains covered with purple volcanic rock.

我试图描述出一些根本没法形容的食物，像是木馏油的香味——发苦的，有点像树脂，但还是很亲切——七月里尖锐凄厉的蝉鸣，柔软如鸿毛的无叶树，广阔无垠的天空，那种发白的蓝色从一侧的地平线一直延伸到另一侧的地平线，极少被覆满了紫色火山岩的低矮的山丘阻断。

In the study area, the thinning-out line of albic horizon is coincident with the 55.74m contour line, and the maximum horizon error was less than 1m and the maximum vertical error less than 0.04m.

基于湿地边界标准的湿地的定义应为：湿地是陆地和水体之间的过渡带，是由于地表淹水／土壤水饱和而形成的一种隐域性自然综合体，其上界位于陆地土壤诊断层的尖灭点处，其下界是有根植物下界。

Linear Fractional Transformation is adopted to translate the control of perturbation to the control of disturbance, then cost index is augmented, and with the min-max method, a robust receding horizon control law is derived. The sufficient conditions for the existence of the control law and closed-loop stability are also presented. The result is extended to time-invariant system with an infinite horizon, and its consistence with the robust control based on the concept of Quadratic Stability is verified.

首先利用线性分式变换，将摄动系统的鲁棒控制问题转化为对扰动系统的鲁棒控制问题；然后通过对性能指标的扩展，利用min-max方法，得到了鲁棒滚动时域控制律，并给出了其存在和使闭环系统渐近稳定的充分条件，并将结果扩展到对定常系统时域无穷的的情况，指出其与现有的基于二次型稳定概念提出的鲁棒控制的一致性。

Firstly, Receding horizon H〓 control based on state feedback with terminal constraints is proposed for systems with disturbance inputs and parameter perturbations. Linear Fractional Transformation and some existed results on Receding horizon H〓 control for systems without perturbations are introduced.

首先针对同时存在外界输入扰动和自身参数摄动的不确定线性时变系统，利用线性分式变换和现有的一些无摄动系统滚动时域H〓控制的结果，得到了基于状态反馈的终端约束滚动时域H〓控制器的设计方法，并给出了控制律存在和使闭环系统渐近稳定的充分条件。

We prove that thecontributions of the quadratic combinations of the extrinsic curvature of the horizon arezero by defining a pair of vectors which orthogonal to the event horizon and dual to oneforms.

计算表明：当取一对与视界面正交且与1-形式对偶的矢量后，视界外曲率的二次项对熵的贡献项为零。

Parallel to or in the plane of the horizon .Of, relating to, or near the horizon .

地平线的地平线的，与地平线有关的，或接近地平线的
