英语中委婉语发展初探

委婉语是一种确保语言顺利进行的最常见语言表达法。作为英语学习者和教育者应就其产生、发展、构成及与社会的关系进行全方位研究,以期提高英语学习者对英语委婉语的认识和运用。     

用点差法巧解中点弦问题

点差法在解决与中点有关的问题时确实很有用。它通过“设点”、“作差”两个步骤。就产生了弦的中点和弦所在直线的斜率,巧妙地避免了解方程组求交点的复杂运算,使问题轻松获解。与常规解法相比,其优越性显而易见。     

法律论证的概念——系统—结构主义的进路

法律论证问题已经受到广泛的理论关注,其中值得注意的是,目前几乎所有界定都有将法律论证与作为一个系统的法律方法等同之倾向。这种界定倾向当然不合理,因为法律论证仅仅是诸多法律方法之一种。以系统论视角来对法律论证进行界定也许可以很好地避免这种倾向。从系统论的角度讲,欲恰切地界定系统中的某种成分,就必须将它还原到系统中,从它与作为整体的系统本身以及系统的其他成分之互动关系的角度来进行。     

论美国区际法律冲突解决方法之借鉴

区际法律冲突来源于一国之内不同的法域,但是在我国则形成了一国两制三法系四法域的特点,这种特殊的区际法律冲突影响着我国区际私法的发展,影响着我国区际法律冲突的解决。文章通过对美国区际法律冲突的解决办法进行分析,提出了适合于我国的区际法律冲突的解决办法。     

Resistance partial factor and reliability of cast ball-and-socket support joint

Considering the uncertainty of material performance, geometric characteristic and analysis method, the analysis of statistical parameters of the resistance of cast ball-and-socket support joints and the reliability analysis are carried out by JC method (improved first-order second-moment method) based on the relevant experimental data. Results show that the resistance partial factor of the joint increases with the increase of the reliability index. The resistance partial factors are suggested corresponding to the reliability index under different load combinations. Moreover, the suggested resistance partial factor is adopted in reliability design, and it is found that the reliability index of the joint is larger than the target reliability index. The optimal load combination is the one in which live load plays an important control role. Finally, based on the suggested resistance partial factors, the reliability analysis of cast ball-and-socket support joints of a project is conducted.     

Numerical Model of Storm Surge and Inundation in Bohai Bay

A two-dimensional numerical model of extratropical storm surge and inundation in Bohai Bay was built based on the unsteady flow Navier-Stokes equations. The model included two sections, one was for the simulation of storm surge tidal level and the other for the simulation of storm surge inundation in the coastal area. While simulating the storm surge tidal level, the alternating direction implicit (ADI) method was applied to dispersing and solving 2D storm surge equations. In the simulation of storm surge inundation, the 2D unsteady flow equations were dispersed and solved using the structureless grids of finite volume method (FVM). A coupling calculation mode of the process of inundation and storm surge tidal level variation was proposed, therefore the storm surge inundation process and area could be calculated while simulating and forecasting the process of storm surge tidal setup. Furthermore, an extratropical storm surge and inundation in Bohai Bay were simulated using this numerical model. Simulation results are in good agreement with the measured data, which shows that this numerical model provides a new method of simulating and forecasting storm surge and inundation in Bohai Bay.     

一种加快的CV模型分割方法研究

CV模型是一种有效的活动轮廓分割模型,其缺点是分割速度慢.用OTSU法预处理后的区域边界作为CV模型的初始轮廓线,大大提高了分割速度,且该方法能克服传统CV法难以分割壁较厚的内部空洞的不足.在CV模型的能量函数中引入惩罚项,使得CV模型在演化过程中无需重新初始化,进一步提高了分割速度.实验表明改进后的CV模型与传统CV模型相比分割速度有了较大提高,且分割效果更好.
