According to Lorentz transformation,the relativistic covariant of electromagnetic field tensor and 4-dimension forces,and the relativistic invariance of electric charge,it can be directly proved that a moving magnetic monopole will be acted- by a magnetic Lorentz force ,and that the magnetic Lorentz force has the same accuracy as the Coulomb low.

概述了磁单极概念的历史发展，从洛伦兹变换出发，利用电磁场张量和四维力的协变性以及电荷相对论不变，直接证明了运动磁单极受磁洛伦兹力，建议了一个磁洛伦兹力的验证方案，并用磁洛伦兹力公式导出狄拉克电荷量子化条件。证明了磁洛伦兹力公式具有与库仑定律相同的精确度

Other attractions include the Haunted House of Ebenezer Scrooge a Pepper's ghost effect,a Victorian school room, a 4D high definition cinema show,"The Six Jolly Fellowship Porters", a themed bar and restaurant, and Fagin's Den, a play area.

其他景点有吝啬鬼埃比尼泽·斯克鲁奇的鬼屋，一个维多利亚时代的教室，一个高清四维影院——"码头工的聚集地"，一个主题酒吧和餐馆，一个游戏区——"费金的老窝"。

The positive fact is an aggregate that includes some elements about the affairs composed,an informatory point in the fourth—dimension while the negative fact is an empty aggregate that includes nothing,a supplementary aggregate of any positive fact.

积极事实是一个包含事实构成要素的集合，在四维时空坐标中对应的是一个确切的点；而消极事实是一个不包含任何元素的空集，是任何一个积极事实的补集。每一积极事实都对应着无数消极事实。

Adopting the method of discontinuity bypass mapping,the Poincare mapping of Jeffcott model near a grazing orbit was estimated as a four-dimensional mapping with square-root compressing or stretching at one direction,from which many chaos motions were found by researching the mapping.

采用不连续穿越映射技术，Jeffcott碰摩转子系统的映射在擦边碰撞附近可以近似为在一个方向上有平方根伸缩的四维映射，本文对此映射的动力学行为进行了研究，而且发现了有大量的混沌现象存在。

This paper uses the most basic physical phenomenon to proof the existence of four dimension times .The paper introduce some way of mathematics, I think this is all simple and easy problem.

本文用最基本的物理现象证明四维时间的存在，并介绍一些本文的数学方法，我想都是些简单易懂的问题。

Here you will be presented to some important skills to control your surface inside Cinema 4D using one of the most complex areas of the Scarab Machine , the Front Light Hood.

在这里，您将被提交给一些重要的技能，以控制您的四维影院内表面使用的圣甲虫机最复杂的地区，前灯胡德之一。

French Open semifinalist Stosur, herself back better than ever after a battle with the debilitating lyme disease, continues to underline her newfound Top 20 status: last week she beat Serena Williams on her way to the semis at Stanford and this week she beat Ana Ivanovic to reach the last eight at Los Angeles.

法国网球公开赛四强的女将，她返回后，比以往任何时候都更好的战斗的削弱莱姆病，继续强调她已20状态：上周击败小威廉姆斯，她对她的半决赛，并在斯坦福大学这个星期她击败伊万诺维奇以达到过去八年在洛杉矶。

Pere Vives Viches from Igualada near Barcelona, Spain, reached the semi finals of the FFWC in Cologne last year, but a new roster of players will fly the Spanish flag in New Orleans, hoping to improve on the fourth place finish of their predecessors.

佩雷里弗斯维奇队来自西班牙巴塞罗那市近郊的英古拉达，球队去年打进了在科隆举行的腰旗世界杯半决赛。全新的阵容将有望帮助西班牙队在新奥尔良跨上新的台阶，他们希望能够超越上一任队员取得的第四名的成绩。

The rise of the superstring/M theory and brane cosmology enables the physicists to be free of the fettering of the 4-d spacetime and provides a whole new visual angle for the CC problem.

超弦理论与膜宇宙论的出现让物理学家们的思路越出了四维时空的羁绊，为宇宙学常数问题的研究提供了一个全新的视角。

According to the clear water experiment, aeration performance of the new equipment is good with high total oxygen transfer coefficient and oxygen utilization ratio.

曝气设备的动力效率在叶轮转速为120rpm～150rpm时取得最大值，此时氧利用率和充氧能力也具有较高值。

The environmental stability of that world - including its crushing pressures and icy darkness - means that some of its most famous inhabitants have survived for eons as evolutionary throwbacks, their bodies undergoing little change.

稳定的海底环境─包括能把人压扁的压力和冰冷的黑暗─意谓海底某些最知名的栖居生物已以演化返祖的样态活了万世，形体几无变化。
