| 1. | With the development of modern industry and technology , some conveying and manipulating operations in non - contact mode need the suspension technology in the fields of guiding system , material processing , micro - electronics and semi - conductor industry and so on . therefore , it is of great importance to develop the suspension technique . there have been some conventional suspension methods at present , among them , magnetic levitation , acoustic levitation , aerodynamic levitation , optical levitation , radio - frequency levitation , electric levitation and super - conducting levitation
随着现代工业与科学技术的发展，在精密机械工业、半导体工业、航空航天工业、交通与运输业以及空间材料科学、微电子学和军事科学等许多领域，需要采用悬浮技术对特定目标如精密元器件、光盘( cd ) 、液晶片( lcd ) 、硅基片( wafer ) 、导航陀螺乃至列车等实现非接触式的操作或输运，因此，悬浮技术的发展具有重要的理论意义和实用价值。 |
