原理
磁悬浮列车利用“同名磁极相斥,异名磁极相吸”的原理,让磁铁具有抗拒地心引力的能力,使车体完全脱离轨道,悬浮在距离轨道约1厘米处,腾空行驶,创造了近乎“零高度”空间飞行的奇迹.
由于磁铁有同性相斥和异性相吸两种形式,故磁悬浮列车也有两种相应的形式：一种是利用磁铁同性相斥原理而设计的电磁运行系统的磁悬浮列车,它利用车上超导体电磁铁形成的磁场与轨道上线圈形成的磁场之间所产生的相斥力,使车体悬浮运行的铁路；另一种则是利用磁铁异性相吸原理而设计的电动力运行系统的磁悬浮列车,它是在车体底部及两侧倒转向上的顶部安装磁铁,在T形导轨的上方和伸臂部分下方分别设反作用板和感应钢板,控制电磁铁的电流,使电磁铁和导轨间保持10—15毫米的间隙,并使导轨钢板的排斥力与车辆的重力平衡,从而使车体悬浮于车道的导轨面上运行.
通俗的讲就是,在位于轨道两侧的线圈里流动的交流电,能将线圈变为电磁体.由于它与列车上的超导电磁体的相互作用,就使列车开动起来.列车前进是因为列车头部的电磁体（N极）被安装在靠前一点的轨道上的电磁体（S极）所吸引,并且同时又被安装在轨道上稍后一点的电磁体（N极）所排斥.当列车前进时,在线圈里流动的电流流向就反转过来了.其结果就是原来那个S极线圈,现在变为N极线圈了,反之亦然.这样,列车由于电磁极性的转换而得以持续向前奔驰.根据车速,通过电能转换器调整在线圈里流动的交流电的频率和电压.
缺点
1.磁悬浮有一大缺点,它的车厢不能变轨,不像轨道列车可以从一条铁轨借助道岔进入另一铁轨.这
磁悬浮列车
样一来,如果是两条轨道双向通行,一条轨道上的列车只能从一个起点驶向终点,到终点后,原路返回.而不像轨道列车可以换轨到另一轨道返回.因此,一条轨道只能容纳一列列车往返运行,造成浪费.磁悬浮轨道越长,使用效率越低.
2.由于磁悬浮系统是凭借电磁力来进行悬浮,导向和驱动功能的,一旦断电,磁悬浮列车将发生严重的安全事故,因此断电后磁悬浮的安全保障措施仍然没有得到完全解决.
3.强磁场对人的健康,生态环境的平衡与电子产品的运行都会产生不良影响.

The source of modern American slang is more extensive.Argot,jargon and blasphemy has produced so many wonderful slang,"such as the American criminal outside the prison society called street (street) that,according to this world is divided into prison and within the two parts,and prison is prison outside,as long as they are not in custody in street,street where is their activities,and the slang is a flop parole is used to refer to." [1] and as "kick the bucket (connected to mean died,die or pass away),this sentence slang is very popular,because in the 7th century Britain,execution,on death row inmates will in the bucket (the bucket),the executioner of bowstring at the neck,then kick the bucket,prisoners could because of ground sora tight and suffocated.Now this sentence slang is widely used to refer to any kind of death way." [2] soldiers,police and students,workers,unemployment the homeless and the driver,prostitutes,criminals belonging to subcultures such various social groups in the contribution of slang is great,they create a total of slang ceaselessly in update,and each has its characteristics.Although some of the jargon or involving sexual slang unbearable pleasant,but do not deny they are the main source of modern American slang one.principle
Maglev train using "the poles,reactive different name the principle of phase" poles,let magnets have resist gravity ability,made the body completely from orbit,suspended in distance orbit about 1 cm,driving in nearly emptied,created "zero height" space flight miracle.
Because the magnet have same-sex reactive and opposites attract two forms,so maglev train has two of corresponding form:one kind is to use the principle and design magnet same-sex reactive electromagnetic operating system maglev train,it USES the car of the magnetic field and form superconductor electromagnet track coil of the magnetic field generated by formed between the repulsion,make body in the railway suspended operation; Another kind is to use magnets opposites attract principle and design of electric power system,it is the maglev train on both sides and reversals in body bottom up top mounted magnet,in T shape of guide rail arms outstretched above and below a part respectively,reaction plate and induction plate,the current control electromagnet electromagnets and guide maintain between 10-15 millimeter clearance,and make guide plate with the repelling force,thus make gravitational balance suspended in the driveway of car guide surface operation.
Popular speak is located in orbit,on either side of the coil flowing alternating current,can will coil into electromagnets.Because it and the superconducting magnets on the train,they made interaction train started up.Train the electromagnet head forward because the train (N extremely) were installed in orbit by former point of magnets (S extremely),and also attracted was installed in orbit of magnets (N a bit later rejected by the extremely).When the train forward,the coil is the current direction of flow reversal came over.The result was originally that S a coil,now a N extremely coil,and vice versa.So,train the conversion and electromagnetic polarity due to continuous forward mercedes-benz.According to the speed,and through the power converter adjustment in the flows of alternating current coil frequency and voltage.
faults
1.A large faults,it maglev train carriage cannot change track,unlike railway train with a railway track turnout from entering another tracks.this
Maglev train
Sample way,if is two rail two-way traffic,a track on the train to end only from a starting point,to the end,the road to return.And unlike railway train,can change to another track returns rail.Therefore,a rail can accommodate eels,wasteful car running back and forth.Magnetic levitation track longer,use efficiency is lower.
2.Because of maglev system is relying on electromagnetic force for suspension,orientation and the drive function,once without electricity,maglev trains will happen serious safety accidents,so after powrefailure maglev security will still not get fully resolved.
3.Strong magnetic field on the person's health,ecological environment balance and electronic products operation will be harmful effects.
