The article s goal is to establish the ship maneuvering mathematical model, simulate the ship s movement in restricted water, to research the width and depth of fairway, speed, lateral distance from the central line and other factors on the bank effect of the ship, and discuss the ship s course keeping ability in restricted waters.
本文通过建立船舶在受限水域的操纵运动数学模型,对船舶在受限水域的航行进行了仿真,以研究航道宽度、水深、船速、船舶偏离航道中心线(船舶离岸的距离)的距离等因素对船舶岸壁效应的影响,并对船舶在受限水域的保向性进行了讨论。

In this paper,the restricted water with free surface under the slamming by a big flat-bottom structure freely falling from a certain height is taken as the research object,and the commercial computational fluid dynamics(CFD) software Fluent is used to investigate the 3D hydrodynamic characteristics of the water by solving the Na-vier-Stokes equations.
采用流体体积函数法VOF方法,考虑限制水域边界条件的约束因素,利用计算流体力学(CFD)商业软件Fluent求解脉冲砰击压力作用下具有自由表面限制水域的Navier-Stokes方程,以分析与观察大型平底结构从一定的高度自由落下砰击限制水域的水面所引起的三维流体动力现象。

Especially with the ship size becoming lager, waters such as the water area near bank, the estuary region, the gulf and the inland channel are becoming shallower and narrower relatively, which are the so-called restricted waters.
近二十年来,随着现代船舶向高速化、大型化、专业化方向发展,船舶操纵变得更加困难,发生海难事故造成的后果更为严重;特别是由于船舶的大型化,以前显得宽阔的水域,如近岸、入海口、港湾和内河航道等船舶航行的水域,随着船舶吃水、船宽尺度的增加,水深相对变浅,宽度相对变窄,成为所谓的限制水域。

In order to give a better prediction for the motion of launching ship in restricted water,the effects of dynamic forces such as wave resistance,viscous resistance,chain force,wirerope force,current force,side thrust and unsymmetrical water area on ship launching were considered.
为了对限制水域内船舶纵向下水运动进行完整而准确的预报,考虑兴波阻力、粘性阻力、锚链力、钢缆力、水流力、横向侧推力的动力效应以及不对称水域等因素对下水运动的影响,针对下水各阶段建立了船体运动模型,提出了一种较为完善的限制水域内下水运动理论计算方法。

超导电性的局域和非局域理论（localizedandnon-localizedtheoriesofsuperconductivity）
伦敦第二个方程（见“伦敦规范”）表明，在伦敦理论中实际上假定了js(r)是正比于同一位置r的矢势A(r)，而与其他位置的A无牵连；换言之，局域的A(r)可确定该局域的js(r)，反之亦然，即理论具有局域性，所以伦敦理论是一种超导电性的局域理论。若r周围r'位置的A(r')与j(r)有牵连而影响j(r)的改变，则A(r)就为非局域性质的。由于`\nabla\timesbb{A}=\mu_0bb{H}`，所以也可以说磁场强度H是非局域性的。为此，超导电性需由非局域性理论来描绘，称超导电性的非局域理论。皮帕德非局域理论就是典型的超导电性非局域唯象理论。
